Description

The present invention relates to an acoustic system for a soundscape, in particular, focusing on the fact that a person recognizes the state of the outside world by the five senses of sight, hearing, smell, taste, and touch.

nothing special

In the scene of environment creation including augmented reality and virtual reality, sound is mainly treated as an object accompanying images, etc., or as an object to be enjoyed under limited prescribed conditions such as so-called music appreciation. It never left the area of being treated.

Light provides highly accurate information about distances, positions and angles in visual space. Vision is a mechanism suitable for the conscious work of further boiling down the information obtained in this way. The eyes as a sensory organ for that purpose are attached only in a certain direction, and also have a mechanism of an eyelid that blocks input. If you don't want to see it, you can easily look away and close it. On the contrary, you can pay attention to somewhere. Vision is a very subjective sensation in which the ego dominates the environment.

On the other hand, sound always reaches us from all directions, so hearing obtains a faithful map from that information and constantly generates the whole picture of sound space in the brain. Although it is a little rough, it is an excellent mechanism for grasping the perspective and direction including time.

Moreover, hearing is designed so that you can always feel it. Why do we wake up with sound when we are sleeping? The sense of sound monitors the whole picture of the environment 24 hours a day, omnidirectionally. In the case of hearing, you can block the input by your own will, and it will be a problem if the switch is turned off by some beat. That is completely different from vision.

I think that the visual sense is the most active in selecting information from the senses of capturing the surroundings, but the auditory sound recognition is made more than the visual sense in places where one's consciousness does not reach.

For people living in cities, there are increasing opportunities for psychological stress. Highly controlled societies, complex relationships, and even accelerating urbanization processes, such as diminishing opportunities to interact with natural greenery, and increasing mental stress year after year. In such situations, welfare spaces to maintain or promote the mental health of employees, meeting rooms to promote communication, spaces to draw out creative ideas, etc. are also essential. And there is a need for environmental design that includes elements other than visual design.

In response to the above needs, for example, attempts have been made to install a mini plant indoors. They originally started as simple interiors for hospitals, offices, and airports, indoor decorations, and have recently been developed for installation as equipment to improve and mitigate the environment and have become popular worldwide. However, the use of auditory sensitivity, for example, to relieve human stress, is not considered.

The present invention solves such a problem, and provides an experience of augmented reality that has never been seen before by taking advantage of the characteristic of the physical existence of sound, and further, a business that gives an experience that has never been seen before. Is to provide a sound system that can provide the technical basis for.

The present inventor forms a place where "people and people" and "people and the environment" interact through sound. It not only enjoys the sound, but also provides a place to notice, discover, and think. Generally, it is said that the visual stimulus and the auditory stimulus received by humans are approximately 93: 7.

And such an extreme ratio is due to the fact that the ratio of visual stimuli has increased with the development of technology and the promotion of the information-oriented society.

On the contrary, from the instinct to supplement this, the sound information inevitably stirs the imagination of the person who listened to it. In other words, it can be said that the information of sound has more power to stir up the imagination of human beings in contact with it and to form an image in the head than other information such as information of images. ..

The present inventor has focused on the fact that sound has this special property, and has come up with the creation of a technical idea utilizing this property. In other words, we focused on the ergonomic nature that human beings have no choice but to provoke a specific reaction to sound information, and by using this so-called law brought about by nature, this point is solved by various methods. We have considered and invented a mechanism to generate various values by actively stimulating and developing various characteristics resulting from it in general human life including daily life / business aspects. Here is the core / essence of the technical idea of the present application.

Surrounded by sound beyond our familiar world with soundscape design that enables people to connect with the environment, for example, as a permanent structure or building according to the environment. It has been.
The idea was to use elements such as sound-making waves, wind, rain, and spring water in the field to provide a place for people to make creative contact with the global environment.

In order to realize the core of the above idea and solve the above problems, the first aspect of the present invention is to acquire sounds generated in the natural world or artificially created personal sounds as a sound system for soundscape. As a triggering function that utilizes the database stored as sound source data and the ergonomic property that humans have no choice but to elicit a specific reaction to sound information, the sound source data is subjected to a predetermined algorithm according to the usage environment. A control unit that extracts data or randomly extracts it regardless of the usage environment,
It is characterized by including a sound output unit that sounds a sound based on sound source data extracted and controlled by the control unit.

As one embodiment of the present invention, it is intended to permeate the technical idea of soundscape (soundscape) into life through "food" as an experience with five senses, and to capture the sound of cooking and tableware as noise. The music that is played including the purpose of hiding them is the so-called BGM, but instead of playing the BGM, we created an accidental composition of the sounds emitted by the equipment and devices designed throughout the cafe, and at that time, It may be characterized by an acoustic system for a soundscape that creates a limited "soundscape of a once-in-a-lifetime meeting".

At this time, many of the conventional BGMs are generally generalized mainly by the selection of the store side, for example, there are cases where they are generalized such as classical music in stores such as coffee shops and enka in stores such as pubs. Therefore, it can be said that creating an accidental composition of sound is a new point of view.

As one embodiment of the present invention, it changes from moment to moment according to the activities of the staff and customers present at the site, and both the customer and the staff play the role of a member of the performance in a very natural manner. In other words, a situation is naturally created in which both performers and listeners are at the same time. By doing so, the customer can enjoy the soundscape of the place, and at the same time, can be positively aware of the joy of participating in it and the existence of the self who contributes to the performance. Furthermore, it may be characterized by a sound system for soundscape that creates new work value and motivation as a "soundscape instructor" as well as a cafe clerk.

As an embodiment of the present invention, as a cafe to enjoy with sound, sound designs are applied everywhere such as doors, chairs, tables, counters, staff, staff uniforms, and various actions of people such as staff and customers who are present in the store. The sound produced by the sound may be characterized by an acoustic system for a soundscape that creates an in-situ sandscape.

As an embodiment of the present invention, when a staff member carries tableware to a table, or when a customer eats or drinks using tableware, a device that makes a sound in response to actions such as moving, placing, or lifting the tableware, or a sound. A sound system for the soundscape of a vessel that is characterized by designing and using a vessel that reminds us of the sound, and the person who touches and uses the tableware like an original instrument naturally becomes a performer and also makes the sound feast. May be a feature.

As an embodiment of the present invention, the menu is displayed as an onomatopoeia (onomatopoeia such as crispy, crispy, and juju), and the sound reminds us of cooking and its texture, taste, and smell, thereby awakening the sensibilities of the ears. It may feature a sound system for soundscapes that let and choose meals by sound.

As an embodiment of the present invention, goods developed from a cafe to an individual's life and incorporating a sound design into daily necessities are not only used in cafes, but also sold in stores and elsewhere, and "living with sound". It may feature a sound system for soundscapes that develop.

As an embodiment of the present invention, a "soundscape lab" is set up in a cafe, research on soundscapes (soundscapes) is conducted, and events and study groups are planned to create soundscapes (soundscapes). It may feature a sound system for soundscapes used to guide and train interested personnel.

As an embodiment of the present invention, an acoustic system for a soundscape that reacts to surrounding sounds, conversations, music, etc., and for example, a light source (LED, etc.) installed in a bottle blinks according to the sound. It may be a feature.

As an embodiment of the present invention, a large audiovisual device installed facing the sea is used, and an audio device that responds to the sound of waves and blinks light is used to make everyday sounds together with light. It may be characterized by an acoustic system for soundscapes that enables clear perception and thereby instills soundscape technical ideas that make the sound of the environment conscious in everyday life. This system is also effective for the hearing impaired because the sound can be sensed by light.

As an embodiment of the present invention, devices that can pronounce using environmental elements in the forest and re-experience the sounds that originally exist in the forest are installed everywhere in the forest, and through those sounds, from the ear to the forest. Can be experienced. For example, it may feature an acoustic system for a soundscape, such as "Wind Shishi-odoshi," which sounds in response to the energy of the wind in the forest.

As one embodiment of the present invention, an acoustic system for a soundscape with an element of "sound orienteering" may be featured.

As one embodiment of the present invention, an acoustic system for a soundscape that connects sounds by a speaker tube in a space separated by a structure such as a wall or a distance may be characterized.

Since the sound runs through every moment and connects us with the event, as one embodiment of the present invention, a wide variety of sounds can be heard from speakers scattered inside the equipment such as a ticket counter, lighting, an underfloor heater, and a bench. Randomly exude fragments and routinely blend into lobbies and aisles. This is a soundscape that is aroused by the fragments of sound floating in this space, and by connecting people's consciousness with various "time" and various "places", it creates multiple layers of time and space. May feature an acoustic system for.

As an embodiment of the present invention, an acoustic program that constantly randomly changes the factors for reproducing sound (sound source extraction location, length, volume, etc.) instead of displaying the sound in an orderly manner like a museum display. By this, various "clouds of sound" are created and floated in the space so that they disappear.

Visitors can discover something from there with free sensibilities while passing through those "clouds of sound" in various ways depending on their flow lines and walking speed. When you suddenly hear from an unexpected place in an unexpected combination, you are far from the original meaning of the sound and evoke various thoughts. Thereby, the relationship between people and sound may be characterized by an acoustic system for soundscapes that can exist as alive without becoming a mere ghost.

As an embodiment of the present invention, we use "ear focus" to live in the world of each sound from time to time, just as there is focus on the eyes. However, since the ears are so conservative, this "ear focus" is fixed, and I usually hear only a limited number of sounds. In addition, he can only listen in a uniform way, categorizing sounds and listening only in habitual chords. For example, when I listen to the sound of waves, I apply it to common expressions such as "Zaboon" and "Zaza", so I don't listen to the individuality and detailed facial expressions of each sound. It is quite difficult to have a free listening style that is free from such habitual and standardized listening styles. However, by training to train the sensibilities of the ears, as a so-called flexible exercise of the ears, it also features an acoustic system for soundscapes that allows you to experience new sounds by listening differently than usual. Good.

As an embodiment of the present invention, the bodily sensation is expanded by hearing sounds that have been heard until now, awakening the sensibilities of deteriorated ears, hearing differently than before, and making new discoveries. It may feature an acoustic system for soundscapes.

When we talk about the environment, we tend to assume only the natural environment, but there are various environments such as the social environment, the economic environment, and the home environment. For a person, the environment can be said to be the various "horizons" that surround him. This "horizon" is conceptual, but it can be said that the various "horizons" that can be seen around you form the environment. If this "horizon" is not conscious, the existence of "I" will disappear. In other words, when the environment is conscious, the existence of oneself is conscious for the first time. If this "horizon" is too vague, or if the relationship between "I" and "horizon" becomes fixed and unconscious, the existence of oneself disappears. There is always a "horizon" of the environment in many ways, and you can find yourself in it. You can recognize yourself because you have an environment, and the world is born there because you have a self. When the "horizon" becomes unconscious, the existence of oneself disappears, and in the limit, the balance of mental survival is jeopardized.

As one embodiment of the present invention, in order to make the environment conscious, a sound may be designed as a medium, and an acoustic system for a soundscape that connects with various environments through the sound may be characterized.

As an embodiment of the present invention, by pouring water into a basin by incorporating it into a tombstone, an altar, etc., the water falls, generates a sound, and by listening to the sound, calms the mind and calms the deceased. It may feature a sound system for a soundscape that can be remembered.

As an embodiment of the present invention, a sound that retains the memory of a river flowing through it with the sound of water, rather than leaving it as a monument of a stone monument engraved with characters such as the ruins of a river. It may feature a sound system for a soundscape realized as a monument.

As one embodiment of the present invention, instead of simply draining the rain that has fallen on the ground as sewage, a sound is generated when the rain falls into the rainwater infiltration basin and echoes in the basin. The sound springs up to the ground through the grating lid on the street and is heard. It may feature an acoustic system for soundscapes that incorporates the sound of rain into the design so that it can express the meaning of returning to the land.

A second aspect of the present invention is a sound generated in the natural world as a sound system for a soundscape, as a evoking function utilizing the ergonomic property that a human has to provoke a specific reaction to sound information. Alternatively, it is characterized by including a sound source unit that expands the sounds around us that are artificially created.

A third aspect of the present invention is that in the first and second aspects, sounds generated in nature or artificially created personal sounds are waves, rain, springs, wind, sunlight, and the like. It may be characterized by utilizing at least one of natural phenomena such as temperature and humidity.

A fourth aspect of the present invention is, in any one of the first to third aspects, a sound generating means for acquiring and listening to sounds generated in the natural world or artificially created personal sounds. It may be characterized by being provided.

With these forms, it is possible to provide an infinitely different experience and enjoyment by sound. By positively utilizing the above-mentioned characteristics of sound, it is possible to create an effect that stirs the imagination of human beings and forms an image in the head. As described above, the present invention positions sound as a core entity, but essentially allows expansion to a physical entity other than sound. Therefore, in the above, a soundscape other than sound is used. May be included in the sound system for.

Instead of playing a fixed, constant melody, it changes randomly. However, at the same time, the placement of sounds (psychological term constellation) allows each listener to hear something like a sequence of sounds or rhythms from among the sounds that fluctuate and change within a limited range. ) Is prepared. It encourages and draws the listener's creativity.

Next, an embodiment of the present invention will be described with reference to the drawings. The embodiments shown below are suitable specific examples in the acoustic system of the present invention, and may be provided with various technically preferable limitations, but the technical scope of the present invention particularly limits the present invention. Unless otherwise stated, the present invention is not limited to these aspects. In addition, the components in the embodiments shown below can be appropriately replaced with existing components and the like, and various variations including combinations with other existing components are possible. Therefore, the description of the embodiment shown below does not limit the content of the invention described in the claims.

FIG. 1 is a block diagram showing an example of a sound generation system 1 showing an example of the present invention.

In FIG. 1, 10 is a sound generator capable of acquiring sounds generated in the natural world, which will be described later, by recording or the like, 20 is a sound output control device for outputting and controlling the acquired sounds as sound source data, and 30 is sound output. It is a sound output device that outputs a sound or the like whose output is controlled from the control device 20.

When the sound generator 10 acquires an actual sound generated in the natural world such as a wave sound, the sound generator 10 does not actually generate a sound like a wind sound or a water drop sound, but uses the generated phenomenon. In the case of a sound that is naturally reminiscent of wind noise or water droplet sound (wind noise, tree fluctuation sound, water droplet sound struck on an object such as the ground), or an artificially created sound. Any form may be used as long as audible sound can be recorded.

Further, the sound generator 10 can directly pronounce the sound and use it as a sound source unit. In the following description, the sound generator 10 will be described in various cases where the sound is created mainly by utilizing a natural phenomenon, instead of manually producing the sound as in a musical instrument, for example. Therefore, in addition to the case of simply enjoying the created sound, the case of using the created sound as a sound source unit for sounding from the sound output device 30 by recording or the like is included.

Therefore, the sound created by the sound generator 10 mainly by utilizing a natural phenomenon is distinguished from "pronunciation", and the sound when the sound is converted into data by recording or the like and output by the sound output device 30 is distinguished from "ringing". explain.

The sound output control device 20 receives the sound output from the sound generator 10 as a evoking function utilizing the ergonomic property that a human has to provoke a specific reaction to the sound information. The sound output control is executed based on the conversion unit 22 that converts the received sound into digital audio data, the storage unit 23 that stores the application that controls the entire system of the present invention, and the application that is stored in the storage unit 23. The control unit 24 and the database unit 25 that stores the digital audio data converted by the conversion unit 22 (hereinafter, also referred to as “sound source data”) in a database state by associating them with a table method or the like according to a predetermined algorithm. A transmission unit 26 for transmitting digital audio data to the sound output device 30 is provided.

For example, the control unit 24 may output and control the transmission unit 26 of the digital voice data stored in the database by a table method associated with the environment or the like, or the environment or the like so as to create an accidental composition of sound. The output of the transmission unit 26 may be controlled by a random method that hardly considers it.

The sound output control device 20 may be, for example, a personal computer having an operation unit such as a keyboard and a display unit such as a monitor, or a device connected to the personal computer.

The sound output device 30 may include, for example, the entire structure in which the speaker or the like is installed, a display screen of the monitor or the like, or the like, in addition to the device that directly outputs the sound of the speaker or the like.

In addition, as buildings / structures to be installed or incorporated, for example, cultural facilities (museums, halls, libraries, museums, religious buildings, etc.), commercial facilities (shopping malls, department stores, restaurants, cafes, bars, tea rooms, hotels, sports, etc.) Gyms, hot spring facilities, beauty salons, etc.), medical treatment facilities (hospitals, care houses, nursing homes, nursing homes, employee rest spaces, etc.), educational facilities (schools, kindergartens, schoolchildren's nursery schools, private schools, etc.), housing (detached houses, detached houses, etc.) Apartments, apartments, etc.), street furniture (bench, street light, bus stop, car stop, etc.), sanitary facilities (toilet, washroom, etc.), other outdoor facilities (garden, garden, tree-lined roads and parks, tombstones, altars, etc.) Create a place where "people and people" and "people and the environment" interact through sounds and the scenes of the place, such as funeral halls, ossuary halls, shrines and temples, and enjoy the sounds and gain new awareness. It is a system equipped with a sound expansion function that can be used as a technical idea and device that provides a place to discover and think, and expands opportunities for effective use of the sounds around us.

Human survival has three aspects: "physiological survival," "social survival," and "mental survival." Among them, the sound design is especially for "supporting mental survival."

As expressed in the Japanese words distant sound (tone), distant fireworks, distant drums, and distant thunder, human beings can exchange consciousness through sounds with distant objects, and sounds are "immediately inseparable" from the environment. It can be said that it brings about the relationship of.

In other words, the sound of the environment gives humans the feeling of being surrounded by the environment and the world surrounding them while maintaining an appropriate sense of distance.

By constructing audio equipment, workshops, and sound education programs that make people aware of the sounds of such an environment, we can solve the problems of mental disorders such as withdrawal and suicide, and support the mental survival of human beings. You can expect it.

2 and 3 show an example of a sound output device 40 provided with a sound expansion function as each of the above-mentioned functions, which expands opportunities for effective use of sounds around us in a store such as a cafe (bar).

As shown in FIG. 2, the sound output device 40 is a sound output control device (a sound output control device) in which sounds generated by objects or people generated in the store from a counter 41, a table 42, a stool (chair) 43, etc. The database is created in (not shown), and the sounds created in the database are played according to the presence or absence of people and the presence or absence of vessels.

"Food" is an experience with all five senses. Through the "food", the idea of soundscape is permeated into life.

In restaurants, BGM is music that captures the sounds of cooking and tableware as noise and plays them for the purpose of concealing them. On the other hand, here, BGM is not played, and the accidental composition of the sounds emitted by the equipment and devices designed throughout the cafe creates a "one-time-one-time soundscape" throughout the store.

It changes from moment to moment according to the activities of the staff and customers who are present, and both the customers and staff will take on the role of a performer in a very natural way. In other words, a situation arises in which both performers and listeners are both performers.

By doing so, the customer can enjoy the soundscape of the place, and at the same time, can be positively aware of the joy of participating in it and the existence of the self who is contributing as a performer. Also, the staff is not just a cafe clerk. As a "soundscape instructor", you can create new work value and motivation.

For example, sound designs were applied to the doors of store entrances (not shown), counters 41, tables 42, stools (chairs) 43, staff uniforms (not shown), and staff and customers were present in the store. The sounds produced by people's various actions create the soundscape of the place.

Further, as shown in FIG. 3, when the staff carries the tableware to the table 42, when the customer eats and drinks using the tableware 44, the table makes a sound in response to actions such as moving / placing / lifting the tableware 44. Emit. These sounds can be pronounced as reverberant sounds by the concave reverberant portion 42a provided on the table 42 as a sound source portion. As the tableware 44 shown in FIG. 3, general-purpose tableware can be used.

By the way, various tableware 44 reminiscent of sound can be used not only as a general-purpose item but also as a specially designed tableware. In other words, as shown in FIG. 3, the person who touches and uses the design tableware 44 like the original musical instrument naturally becomes the performer. The tableware 44 shown in FIG. 3 is an example of five types, and from the left in the figure, tableware that produces sounds corresponding to onomatope such as "chororo", "carokaro", "cheep-cheep", "saku", and "two". It is designed as. Although not shown, the onomatope drawn on tableware, cutlery, tablecloths, etc. can be seen and hidden while using it, so that the sound can be felt even if the sound cannot be actually heard.

Although not shown, the menu is displayed in onomatope (crispy, crispy, juju, etc.), and the sound reminds us of the food and its texture, taste, and smell, which can awaken the sensibilities of the ears. It is possible.

In addition, various goods incorporating sound designs, such as these tableware 44, are not only used in cafes, but are also sold in stores at the same time so that each can develop a "living with sound" as daily necessities. You may.

Water is actually flowing in the counter 41, and you can eat and drink while listening to various water depending on where you sit. Further, the counter 41 and the table 42 are provided with a bottle 45 having a built-in light source unit 45a that shines in response to sound, and the effect of sound and light can be used together.

In the bottle 45, for example, the light source unit 45a is dimmed in response to the sound of the tableware 44, and the bottle 45 can be turned on, blinked, and turned off.

As the bottle 45, for example, an empty bottle of wine, sake, shochu, or the like can be used. As a result, in addition to the bottle recycling function, it is possible to add a bottle memorial function that allows the bottles of memories and favorite bottles to be stored while being used in daily life. In addition, the bottle 45 can also be used as an emergency light by switching to constant lighting in the event of a disaster.

The light source unit 45a can be incorporated into various daily necessities other than bottles (for example, mugs, coasters, muddlers, tables, etc.) so that the idea of soundscape can be experienced in everyday life. To do.

As a result, the bottle 45 reacts to surrounding noises, conversations, music, etc. in real time, and the light source unit 45a such as an LED installed in the bottle 45 can be blinked according to the sound.

The light source unit 45a is provided with an illumination LED light that shines in response to sound inside a colorless transparent or colored transparent bottle 45. It can be provided with a visual display function according to the size.

For example, the light source unit 45a can amplify the sound acquired by the condenser microphone by the inverting amplifier circuit of the operational amplifier, and amplify the sound until the light source unit 45a such as the LED light source lights up to adjust the sensitivity.

If the bottles 45 are arranged at a plurality of places on the counter 41 (and the table 42) as appropriate, the light source unit 45a lights (or blinks or dims) for the visitor sitting at that place, and the rhythm of the sound is produced. It is an organic rhythm of light and can be visually recognized as if it were a living organism of light. The counter 41 and the table 42 may be provided with a light emitting device 46 instead of the bottle 45.

In this way, the bottle 45 and the light emitting device 46 react in real time to the surrounding environmental sounds, conversations, music, etc., and the light blinks according to the sound, so that the sound is more clearly perceived together with the light. Can be made possible.

As shown in FIG. 3, the stool (chair) 43 has a trumpet-shaped diameter that is upward so as to form a seat surface and can emit sound. For example, as shown in FIG. 3, the stool (chair) 43 visits the store. When the person is sitting, the seat surface is blocked by the user's body to prevent the sound from being emitted, and as shown in FIG. 3, when the visitor is not sitting, the sound generated by the sound output device 30 can be heard. It has become like.

Therefore, the stool (chair) 43 may be provided with a seating detection sensor (not shown) such as a pressure sensor, and the sound output device 30 may be sounded only when the chair is not seated.

By the way, in the above embodiment, the explanation was given for a cafe store, but by designing the sound as a medium (catalyst) instead of the music as an expression or the BGM that directs the space, the people, facilities, and regions It is expected to create new relationships. In addition, the sound inspires a new spatial experience.

For example, speakers are embedded inside various equipment such as ticket counters, lighting, underfloor heaters, and benches. A wide variety of sound fragments may be randomly exuded from these scattered speakers and spilled into the lobby or aisle on a daily basis.

These sounds are not displayed in an orderly manner like the ones displayed in museums, but the factors that reproduce the sounds (selection of sound source, extraction playback location, extraction playback length / volume, etc.) are always randomly changed. The sound program allows us to float in space so that clouds of various sounds are born and disappear.

Collage of existing songs and the use of real sounds as sound materials, as in contemporary music, have already been practiced in the field of Western contemporary music for more than half a century.

However, in the design of sound as a medium (catalyst), sound fragments continue to be reconstructed by chance. It exists not as a work presented at concerts as a composer's self-expression, but in everyday time and space, constantly changing and updating. Therefore, the design of sound as a medium (catalyst) is a new attempt to encourage the general public, who is not the audience of the concert, to listen to it discoverably and creatively.

FIG. 4 is a graph showing variable factors when playing back the selected sound source. For one selected sound source, programming can be created so that the four factors shown in this figure fluctuate each time it is played. That is, the length of time that the sound source fades in, the length of time that it lasts, and the length of time that it fades out changes randomly each time it is played, and the sound pressure level of that sound source. The maximum value also changes randomly each time it is played. As a result, even with the same sound source, it is possible to change the sound into a variety of sounds, such as a sound that disappears in an instant, a sound that reverberates for a long time, and a sound that resonates loudly up close.

The user can discover something from it with free sensibility while passing through the clouds of sounds in various ways according to each flow line, walking speed, and so on. Aroused by the fragments of sound floating in this space, people's consciousness is connected to various "time" and various "places", creating multiple layers of time and space.

As a result, the relationship between people and sound remains alive, without becoming a mere ghost. In addition, by collecting and accumulating these sounds through workshops, etc., the following effects can be achieved as an enlightenment activity for the idea of soundscape and as "sound education (otoiku)".
・ Lead people to "rediscovery of sound", "reproduction of meaning of sound", and "reorganization of soundscapes".
・ Experience the sounds around you again so that you can listen creatively and discoverably.
・ Awakens the sensibility of deteriorated ears.
・ Through sound, open awareness to the surrounding environment and provide environmental education to think about.

In the database 25 described above, about 500 sound sources are always stored, and they are randomly extracted, and it is possible to randomly change which part of the extracted sound sources is to be reproduced. .. There, the sound hierarchy is dismantled, for example, tables such as "traditional festival sounds representing the region", "our cat's sneezing" and "mama's chorus practice voice" are equivalent sounds. Treated on the same horizon.

(Sound generator for natural use)
There is a survey case that the fishing village of Les Conil in France is an "acoustic community (the definition of vocabulary will be described later)". Since this area is surrounded by the sea on three sides, the soundscape is also changing due to the periodically changing sea breeze and land breeze.

Since the wind carries the sound, the soundscape of the fishing village changes clockwise as the wind moves in the day.

Specifically, in the early morning, the sound from the north such as the bells of the church and the mechanical noise of farm work, the sound of the buoy of the ship off the east coast at around 11 o'clock, and the motor of the ship from the south coast at noon. The sound, the sound of a ship buoy off the western coast at around 14 o'clock, the sound of a whale squirting around 16 o'clock in the evening, etc. are carried by the wind and heard. Also, when it is foggy, the sound of the fog whistle is carried by the wind and can be heard.

As a result, the people of the local fishing village feel the changes in these sounds, read the time and weather, and judge that they are useful for their daily lives.

In this way, a community that obtains information from sounds and makes various judgments in daily life or in a specific environment can be called an "acoustic community."

Furthermore, by removing the distinction between the beautiful sounds of musical instruments (hereinafter, also referred to as "musical sounds") and the dirty "noise", the above-mentioned mechanical sounds of agricultural work and motor sounds of ships are included. It is important to return to the same horizon and listen to it again.

Therefore, in the environment in which I am now, various sounds that happened at that time, such as the noise of the audience, the sound of pouring water into the cup, and the sound of the shoes of a walking person, which occurred in the concert hall. It is necessary to listen to the sounds that happen to occur in the place and hear them in the same way as music, that is, to be aware of the "environmental sounds" that are originally there.

In this way, we should be openly involved in "environmental sounds" such as sounds that occur in our daily lives, sounds around us, and sounds of nature that are neither musical sounds nor noise. You can develop your sensibility with.

On the other hand, the human ear is conservative, coupled with the tendency to prioritize the video information that comes from the eyes. For this reason, it is said that the "ear focus" is more likely to be fixed than the "eye focus", and usually only a limited number of sounds are heard. In addition, the way of listening can only be uniform, and the sound is categorized and listened only in the habitualized chords. For example, when listening to the sound of waves, we apply it to common mimicry expressions such as "Zaboon" and "Zaza", so the reality is that we do not listen to the individuality and detailed facial expressions of each wave sound. ..

It is surprisingly difficult to have a free listening style that is free from such habitual and standardized listening styles.

Therefore, as shown in Fig. 5, sound expansion that expands the opportunities for effective use of the sounds around us as a means of listening to these facial expressions with reference to one wave sound and disclosing the world of new encounters with the sea through sounds. We have developed a wave sound generator 50 having a function.

The naturally derived wave sound acquired by the wave sound generator 50 can be used as the sound generator 10 by recording it through a microphone (not shown). Further, if necessary, another sound can be used as the sound output device 30 by sounding another sound so as to overlap with the wave sound through the speaker.

As shown in FIG. 5, the wave sound generator 50 can be said to be a huge stethoscope facing the sea. As shown in FIG. 6, for example, the wave sound generator 50 is installed at a plurality of locations (10 in the figure) of the pier 51. The wave sound output device 50 has a different amount of protrusion from the upper surface of the pier 51, and is provided in consideration of the height from an adult to a child.

As shown in FIG. 5, the horn-type sound collecting unit 52 as a sound source unit located below the pier 51 and opening downward is installed in various directions and depths (heights), for example. , A slight wave sound when a wave recedes to a shell attached to a structure (not shown) of a pier 51, a dynamic wave sound of a wake wave, and the like are collected in a sound transmission tube section.

The sound transmitting tube portion 53 located from the lower side to the upper side of the pier 51 has the upper end of the sound collecting portion 52 connected to the lower end thereof, and the lower end of the discharging portion 54 connected to the upper end thereof.

The horn-type emission portion 54, which is located above the pier 51 and expands and opens upward in diameter, is provided with an acoustic reflection portion 55 having a convex surface.

The sound of waves keeps changing every moment due to changes in wave conditions and tide levels due to the weather, and although it is difficult to recognize just by looking at it, there are vertical fluctuations of about 2 m per day. This change in tide level can be recognized by the change in sound obtained from the ear.

The surface side of the sound reflecting portion 55 facing the opening end of the emitting portion 54 has a convex shape, and is inclined so as to open the opening end of the emitting portion 54 toward the upper side. The directivity is designed to diffuse into.

The diameter of the sound transmitting tube portion 53 is determined based on an experiment to a diameter suitable for the sound to be transmitted (in this example, the sound of a wave, but may be a human voice or the like).

The method of installing the sound transmission tube portion 53 preferably has the highest propagation rate. At this time, if necessary, an outer tube 57 is provided on the outside of the sound transmitting tube portion 53 to form a double tube, so that a bending shape or the like that minimizes sound insertion loss can be adopted.

By the way, an example of the experimental results in an anechoic chamber is shown. 7 to 10 are comparison graphs of propagation by pipe diameter, and FIG. 11 is a comparison graph of speech intelligibility by pipe diameter.

The wave sound output device 50 also has different wave sounds depending on the length of the sound transmitting tube portion 53 from the lower surface of the pier 51, the position and direction of the sound collecting portion 52, and the like.

Further, the wave sound output device 50 may be provided with a mark (not shown) for recognizing how much it protrudes from the pier 51 and how much it dives from the pier 51.

As a result, the user may stop at the pier 51 and listen to the wave sound from the specific wave sound output device 50 while checking the mark, search for the sound to be heard while walking on the pier 51, or tide level from the wave sound. You can enjoy the relationship with the sound of the waves by guessing and moving your body up and down.

Further, for example, a light source unit 56 that turns on, blinks, and turns off the portion of the pier 51 that is visible from above can be provided in the sound transmitting tube unit 53 in response to the sound of waves.

The light source unit 56 is provided with a plurality of illumination LED lights that shine in response to sound along the height direction, so that the shining height provides a visual level display function according to the actual wave height and wave sound. Can be equipped.

For example, the light source unit 56 can amplify the sound picked up by the condenser microphone by the inverting amplifier circuit of the operational amplifier, and amplify the sound until the LED light source is turned on to adjust the sensitivity.

Since the wave sound output devices 50 are arranged at a plurality of locations on the pier 51, the light source unit 56 is randomly lit (or blinking or dimmed) at a level corresponding to the location, and the rhythm of the sound is organic in the natural world. The rhythm of light can be used to visually recognize the height of waves and the height of sound as if it were a living organism of light.

The wave sound output device 50 can create a database by recording the wave sound with a microphone (not shown) or the like when the wave sound is taken in from the seaside pier 51 and sounded above the pier 51. Further, it can also be used as a sound output device 30 by sounding another sound through a speaker (not shown) so as to overlap the wave sound emitted from the emission unit 54 as needed. Further, the wave sound output device 50 can be designed so that it can be charged even with sunlight.

Further, as shown in FIG. 6, a wave sound listening bench 60 is installed on the coastline. The wave sound listening bench 60 has wavy or mountain-like undulations in the length direction so as to have a huge net-like bench function of 6 to 7 m in width and 70 to 80 m in length installed at the tip of a wharf protruding into the sea. The bottom is at a height away from the sea surface, and the sea is directly below. The height from the sea surface to the bottom is set to be, for example, about 2 m away from the sea surface (without waves) at high tide.

As shown in FIG. 12, for example, the wave sound listening bench 60 is set to have undulations so that it can sit, lie down, or walk on an appropriately raised portion above the sea surface.

Specifically, as shown in FIG. 13, the wave sound listening bench 60 has a frame shape or a grid shape formed of an arbitrary three-dimensional curve, which is hung on a concrete structure 61 cast in a rail shape in the longitudinal direction. It is a structure in which a mesh-shaped metal 62 is covered on a steel frame material (detailed not shown) assembled in the above.

The material of the bench body 62 is not limited to metal. Further, the bench main body 62 is fixed to the support column 61 via a connecting member 63 having a cushioning property.

This allows users to find stumps and rocks, for example, while walking in the woods, and sit there to eat or rest as well as fit their body. You can experience the feeling of being wrapped in the sound of waves in a free style by using your favorite bulges and dents.

In addition, humans can easily recognize the sense of distance to the sound coming from the front, but in combination with the sensitive reaction to the sound from the back, the sound of waves from a position more than 2 m away is 1 /. It can be felt as a wave sound approaching about 10.

Further, even in such a wave sound listening bench, it is possible to capture the wave sound from the microphone and record it, and to make other sounds sound from the speaker. It is also effective to install such a bench not only on the sea but also on the forest, which allows you to experience the sound generated in the forest from a different position from a bird's-eye view. to enable.

FIG. 14 shows a water droplet sound generator 70 that artificially generates the dripping sound of water droplets.

The water drop sound generator 70 uses abundant spring water to generate sound, and uses the slope behind the building 71 to guide the spring water from the spring point above it with a gradient to supply water. After the spring water is passed through the filtration tank 74 according to the opening degree of the valve 73, water droplets are dropped from the dropping device 76 installed in the tower 75 of the building 71 toward the sounding body 77 as the sound source unit. There is.

As shown in FIG. 15, the dropping device 76 includes a plurality of water distribution pipes 76a branched by the water storage tank 73, and a dropping body 76b connected to the water distribution pipe 76a.

As shown in FIG. 16, the sounding body 77 is located above the well 78 for collecting water droplets and is formed in a hollow cylindrical shape made of metal, and those having different sizes depending on the opening diameter of the well 78 are irregular. Multiple are placed in.

The number of sounding bodies 77 is larger than the number of the dropping bodies 76b installed in the dropping device 76. This is because the sounding body 77 receives the water droplets randomly diffused by the dropping body 76b underneath to generate a sound.

As shown in FIG. 16, a plurality of slit portions 77b are spirally engraved on the top plate portion 77a on the front surface side of the sounding body 77, whereby the lead portion 77d is formed. Since the central portion 77c of the spiral is not the center of the circle of the top plate portion, the lead portions 77d having different shapes are formed. Various variations of sound can be created by the difference in shape.

The top plate portion 77a and the body portion 77e are integrated by full welding (or die casting), and the vibration of the top plate portion 77a is transmitted to the body portion 77e to generate a resonance sound.

Therefore, by making the thickness and diameter of the main body and the depth and spacing of the slit portions different, even when the same amount of water droplets are dropped on the sounding body 77, the dropping sounds can be made different. In addition, the amount of spring water that springs out differs depending on the weather, etc., and for example, by making the amount and interval of water droplets dropped from the dropping device 76 and the dropping position on the sounding body 77 different, the rhythm of various variations in the dropping sound.・ It is possible to create pitches and timbres.

The well 78 is provided on the bottom surface of the tower 75. As a result, for example, as shown in FIG. 14, by moving the stairs 79 provided in the tower 75 up and down, the user synergistically produces the direct sound from the sounding body 77 and the reflected sound in the tower depending on the position. You can listen. The sound is designed to propagate above the tower 75 by inclining one of the walls of the well 78 by 3 degrees.

In this way, the water drop sound generator 70 stores the filtered spring water in the water storage tank 74, and then drops a part of the filtered spring water toward the sounding body 77 to generate dropping sounds having different tones. There is. Further, the dripping sound can be recorded through a microphone or the like (not shown) and stored in a database. Further, the dripping sound may be sounded in real time by a speaker or the like in the facility.

Further, also in such a water drop sound generator 70, it is possible to capture the drop sound from a microphone (not shown) and record it, and to make another sound overlap with the water drop sound from a speaker (not shown). .. Further, the spring water stored in the well 78 can be supplied to, for example, the terraced rice fields downstream.

FIG. 17 shows an example of the output system 80 when the sound generator is installed in such a large building.

As shown in FIG. 17, in the output system 80 shown here, the hall, the conference room, the entrance, the corridor, etc. of the building are divided according to the space or the structure of the building, for example, the sound. A personal computer 88 in which commands including the necessity of output are adjusted and controlled, an interface 84 that receives the commands, a plurality of equalizers 85 that are output-selected by the interface 84, some equalizers 85, and some other equalizers. It includes an hour amplifier 86 that amplifies and controls the output from the 85, and a speaker 87 that outputs sound by the output of the power amplifier 86.

Speakers 87 are installed in halls, conference rooms, entrances, corridors, etc. of structures, but all speakers 87 are built in so as not to be seen in lighting fixtures, benches, and heaters.

A personal computer 88 that controls selection of a sound source and reproduction of the sound source is connected to the interface 84, and can be operated and monitored by the monitor 89.

FIG. 18 is an explanation of an example of a water droplet sound generator 90 equipped with a sound expansion function that expands opportunities for effective use of surrounding sounds by collecting rainwater from the roof and generating a water droplet sound with a sounding tube in rainy weather. It is a figure. This sound can be used as a device to appeal and raise awareness of "disaster prevention" during heavy rains. Further, it may be a device incorporating a mechanism for generating sound due to rain while storing rainwater in a water tank for disaster prevention.

The water droplet sound generator 90 draws a part of the rainwater that has fallen on the roof 91a of the building 91 into the inside of the building 91, and allows the water droplets to pass through the inside of the upper pillar 92 and the lower pillar 93. Water droplets that have fallen on the sounding body 94 as a sound source unit arranged at the lower end of the inner pillar 93 are used for sounding.

The roof 91a is provided with a gutter portion 95 for collecting the rainwater that has fallen. A part of the rainwater collected by the rain gutter part 95 is discharged from the eaves gutter part 95 as it is, and a part of the other part is drawn into the water pipe 96.

On the indoor side of the building 91, an upper pillar 92 penetrating the roof floor portion 91b that vertically partitions the first floor portion and the second floor portion is arranged so as to extend in the vertical direction. The lower end side of the downwardly inclined water pipe 96 is connected to the upper end of the upper pillar 92. At the lower end of the upper pillar 92, a funnel portion 92a is provided to guide rainwater drawn from the water pipe 96 toward the center to prevent water splashing.

The upper pillar body is located at 92, for example, the roof 91a of the two-story building 91 from the second floor portion to the middle of the first floor portion. Below the upper pillar 92, the lower pillar 93 is arranged so as to be separated downward from the lower end.

The lower part of the lower pillar body 93 is fixed to the floor portion 91c of the first floor portion. Inside the lower part of the lower pillar 93, a sounding body 94 is arranged, which sounds when water droplets accumulated in the funnel portion 92a are dropped while passing through the lower pillar 93 along the inner wall surface of the upper pillar 92. There is.

A drainage gutter 97 for collecting dropped water droplets is provided at the lower end of the lower pillar body 93, and sewage treatment is performed below the floor portion 91c.

The sound generated by the water droplets that have fallen on the sounding body 94 leaks to the outside from the gap 98 between the upper pillar 92 and the lower pillar 93.

In this way, the water drop sound generator 90 drops a part of rainwater toward the sounding body 94, and the dropped sound can be recorded through a microphone or the like (not shown) and stored in a database. Further, another sound may be superimposed on the dropping sound by the ringing of a speaker or the like (not shown).

19 and 20 show a water droplet sound generator 100 provided with a sound expansion function that expands opportunities for effective use of sounds around us by using water generated from humidity as water droplets.

As shown in FIG. 19, the water drop sound generator 100 has a plurality of pillars 101, a beam 102 straddling between the upper ends of the pillars 101, and an inverted conical shape arranged downward at a plurality of positions of the beam 102. It includes a pot 103 and a sounding body 104 as a sound source unit arranged below the pot 103.

The pot 103 is made of terracotta, and moisture seeps out from the entire pot 103 to the outer surface due to humidity, and gradually aggregates at the lower end. The water aggregated in the pot 103 becomes large water droplets and falls from the tip of the pot 103. The tip is rounded rather than sharpened so that large water droplets are generated.

The sounding bodies 104 do not need to be arranged directly under the pot 103, and for example, as shown in FIG. 20, a large number of sounding bodies 104 are randomly arranged on the assumption that water droplets swept by the wind will fall during the fall. There is.

Therefore, depending on the strength and direction of the wind at that time, even water droplets that have fallen from the same pot 103 do not always fall to the same sounding body 104, and may fall to a position outside the sounding body 104. .. In addition, it may not hit the sounding body 104 and may fall to the surface of the water to generate a water sound. In other words, a large number of pots 103 can produce unpredictable tones.

As shown in FIG. 20, the water droplet sound generator 100 is arranged on both sides along the path sandwiching the path 105, and can be heard by walking along the path 105.

In this way, the water droplet sound generator 100 drops water droplets generated from humidity toward the sounding body 104, and the dripping sound can be recorded through a microphone or the like (not shown) and stored in a database. Further, another sound may be superimposed on the dropping sound by the ringing of a speaker or the like (not shown).

FIG. 21 shows a sound expansion function that expands the chances of effective use of the sounds around us by capturing the sound (or wind sound) at the time of power generation acquired by the wind sensor 111 and making it possible to hear the sound from a distant place. It is explanatory drawing of an example of the wind noise generator 110 provided.

In addition, the wind noise generator 110 can also be used as a device that appeals and raises awareness of "environmental issues" by sound.

That is, in addition to a device incorporating a device that generates sound with wind energy while generating wind power using a windmill-shaped wind sensor 111, a device that generates sound with solar energy while generating solar power is incorporated. It may be a device.

Unlike waves and springs, wind is a relatively familiar natural phenomenon, and wind chimes are known for the sounds that use the wind. The user can feel the presence and strength of the wind by listening to the sound of the wind chime without feeling the wind itself. It makes it possible to perceive the existence of the invisible wind from the ear.

The wind speed and direction of the wind actually blowing on the wind hill are signaled in real time, and in response to that information, air is sent to a nozzle provided in the sound source unit 112 arranged below the wind sensor 111 (not shown). It is sprayed through a pile of pipes (not shown) of various lengths.

The sound produced by the air blown onto the pipe travels through a 40 m speaker tube buried in the ground and reverberates in a well-drilled cavity 114 below the bench 113. Then, the sound is expanded and reflected by the acoustic reflector 115 arranged at the bottom of the cavity 114, and the sound becomes like a wind blows through, and rises from under the bench 113.

The wind sensor 111 senses the information of the wind blowing to this place in real time, blows out air from the nozzle of the sound source unit 112 according to the information, and blows it to the accumulation of pipes to make a sound and sound. ..

The principle of pronunciation generated by the pipe of the sound source unit 112 is the same as that of a boat whistle called "Bo" generated when the mouth is attached to the edge of the bottle mouth and sprayed.

Since the nozzle of the sound source unit 112 blows air onto pipes of various lengths while moving, the sound changes slowly.

Then, this sound reverberates in a cavity 114 that is dug deep like a well below the bench 113 through a sound transmitting tube 116 about 40 m underground, and is reflected by the acoustic reflector 115 so that the wind blows through. It becomes a sound and rises to the ground.

This sound can be reverberated within a radius of about 5 m around the bench 113, so unlike a clear tone city such as a musical instrument such as a flute, the sound of the wind blowing through, the wind, is rather. You can hear the fricative sound that slips through.

At this time, for example, the sound of a jet that an airplane passes far away irregularly from a speaker provided in the cavity 114, or the sound of rubbing leaves of trees according to the passing timing and strength of the wind detected by the wind sensor 111. , May be sounded.

Inside the sound source unit 112, in response to the wind force detected by the wind sensor 111, when the wind force is strong, a large amount of air is emitted and the nozzle is moved quickly, so that a relatively loud wind noise changes quickly. Similarly, when the wind is weak, a small amount of air is released and the nozzle is moved slowly, so that the faint wind noise changes gently.

In addition to the voice of this wind, the sound of leaf slippage and the sound of airplanes that sometimes occur on the spot are added, and as you listen to the duo, your consciousness opens to the environment. Recent funeral homes have a structure that does not emit smoke, but it can be expected to become a requiem in a sense by turning the sound into that smoke and diffusing it from the ground to the sky. ..

Further, it is also possible to convert the wind sound at this time into a scale, match the musical score with the staff notation, and display it on the monitor 117 installed in front of the bench.

Sound generators that can pronounce using the elements of the natural environment, for example, the environment that exists in the forest, and allow you to experience the sounds that originally existed in the forest, are installed throughout the forest, and through those sounds, By making it possible to experience the forest from the ears, it is possible to provide a sound expansion function that expands the opportunities for effective use of the sounds around us.

By doing this, it is possible to rediscover and realize the forest from the ears, to aurally expand and enrich the forest experience, and to increase the value of the forest. It can also function as a "place to support mental survival" for humans. Furthermore, by continuously holding the workshop "Sound Orienteering" in this forest, it will become a place for environmental education "Sound Education Program" by sound and enlightenment of soundscape thought, and at the same time, it will be a forest that is left unattended and devastated. It is also possible to make it useful for the maintenance, management and operation of.

Sound generators 120 that generate sound in response to changes in various environmental elements (wind, sun, temperature, humidity, flooding, people, etc.) existing in the forest are scattered in the forest. Through the sound, we connect our consciousness to the forest environment.

22 and 23 show a sound generator 120 having a deer function using the wind speed of the forest.

As shown in FIG. 22, in the sound generator 120, for example, wind vehicle bodies 122 are arranged at a plurality of locations in the north, south, east, and west around the outer wall surface of the cylindrical building 121, and the wind generated in the forest is used. is there.

As shown in FIG. 23, in the sound generator 120, when the wind body 122 receives the wind and rotates, the reel portion 123b rope (may be a belt or the like) 124 is wound up by connecting the clutch 123a provided on the rotating shaft 123. ..

The rotating shaft 123 is rotatably supported by the building 121 via a plurality of bearings 123c, a gearbox 123d is provided on one side of the reel portion 123b (the side close to the clutch 123a), and the other side of the reel portion 123b. A brake box 123e is provided on the side (the side far from the clutch 123a).

A weight member 125 is provided at the free end of the rope 124 that can be wound by the reel portion 123b, and when the clutch 123a is released from cooperation and the braking of the brake box 123e is released, the reel portion 123b is due to its own weight. The rope 124 in the wound state can be pulled out from the reel.

A sound source 126 as a sound source is provided below the weight member 125, and an impact sound is produced when the weight member 125 falls.

On the other hand, inside the building 121, an acoustic reflector 127 is provided at least above the sounding body 126 so that the sounding body 126 can be diffused while being expanded.

In this way, when the sensor 128 detects that the wind body 122 rotates due to a constant wind and winds the rope 124 around the reel portion 123b, the sound generator 120 brakes the brake box 123a under the control of the control device 129. It is released, and the weight member 125 provided at the free end of the rope 124 falls due to its own weight to generate an impact sound that strikes the sounding body 126.

Various materials (metal, wood, etc.) can be used for the sounding body 126, and the size thereof is also various by making it different corresponding to each of the plurality of wind body 122 arranged in the building 121. It is possible to make the sound resonate. Since which wind body 122 operates is determined by the wind direction, the sound changes according to the change in the wind direction. Further, since the operating rate of the wind body 122 differs depending on the wind speed, the frequency of sound generation changes depending on the strength of the wind.

In this way, the sound generator 120 uses wind speed to sound the sounding body 126, and the impact sound can be recorded through a microphone or the like (not shown) and stored in a database. Further, another sound may be superimposed on the dropping sound by the ringing of a speaker or the like (not shown).

FIGS. 24 and 25 show a footstep sound generator 130 provided with a sound extension function that expands opportunities for effective use of sounds around us by using footsteps during walking.

The body sensitively senses changes in the quality of space using footsteps as an index. The act of walking is to work directly on the space and produce a sound, and that sound is a reaction to the act. It is a physical and direct interaction with the environment. While listening to the footsteps of others that overlap with their own footsteps, one can form a relationship between oneself and others and further position oneself in the environment.

Unlike the above examples, the footstep generator 130 does not use the laws of nature, but is pronounced by an artificial act (walking). For example, in indoor and outdoor facilities (concert venues, various stadiums, etc.) Audience seats and floors can be used, and benches and decks installed in parks and the like may be used.

As shown in FIG. 25, the footstep generator 130 has a vibration isolator 132 fixed between the foundations 131 and a sound source 133 as a sound source on the upper surface side thereof.

The sounding body 133 may be made of wood, made of metal, or other material that can be sounded with almost no bending even when a person walks, and various types and sizes are used to make the footsteps sound. , Stone, ceramics, plastic, FRP, etc. other than wood and metal may be used as long as the change can be produced.

The cavity provided under the sounding body 133 allows the footsteps generated during walking to be echoed. The cavity may be, for example, a hollow member 136 made of metal or the like as shown in FIG. 24.

As a result, it is possible to play various tones depending on the weight of the pedestrian and the type of shoes, in addition to the tones and pitches caused by the material, size, thickness, etc. of the sounding body 133.

For example, the footsteps echoed by the hollow or hollow member 136 can be recorded through a microphone or the like (not shown) and stored in a database. Further, another sound may be superimposed on the footstep by the ringing of a speaker or the like (not shown).

FIG. 26 shows an example of the dialogue device 140 that communicates through the ear. A large circular space is connected by a speaker tube 141, and trumpet-shaped utterance and reception diameter expansion portions 142 and 143 are provided at both ends thereof to enable conversation.

27 to 29 are designed so that a sound / music-related book and a sound source related thereto are close to each other and can perform operations such as reading / listening / searching while associating the book and the sound source with each other. An example of the sound output device 150 as a bookshelf is shown. This is also effective in avoiding "headphone deafness", which WHO has issued a warning in recent years.

The sound output device 150 is provided with a bench 152 in the middle of the bookshelf 151 so that a user can sit on it.

Above the bench 152 of the bookshelf 151, a super-directional speaker 153 that emits sound only to the user sitting on the bench 152 is provided. Further, below the bench 152, a sound source unit 154 such as a woofer system is provided. This is a special specification when the super directional speaker 153 is used.

Normally, the super-directional speaker (153) is used for announcements by voice in museums, etc., and is suitable for reproducing the midrange, but it is a natural sound / environment with a wide range from low to high. Not suitable for reproducing sound.

Therefore, it is desirable to modify the circuit of the super-directional speaker (153) to extend it to the high frequency range so that it has performance suitable for reproducing natural sounds and environmental sounds. In addition, a low-frequency speaker is added to the modified super-directional speaker (153) to supplement it, and final adjustment is performed on-site so that the phases of the two speakers do not shift.

The sound source unit 154 may be provided with, for example, a high-sensitivity microphone (not shown) for recording a sound of a user turning a page of a book.

As shown in FIG. 28, for example, the sound source unit 154 outputs the audio data from the analog sound source unit 161 to the modulation signal generation unit 162 or the high resolution sound source unit 163 according to the data. The high resolution sound source unit 163 outputs a sound source signal to the controller 164.

The sound source signal is a super directional speaker via a DAC 165, a preamplifier 166, and a power amplifier 167 that convert a digital sound source signal into a signal corresponding to a woofer speaker 155 built in the super directional speaker 153 and the sound source unit 154. It is output to 153 and the woofer speaker 155.

The preamplifier 166 selects an input source (original sound source, CD, MD, tuner, etc.), adjusts the sound quality, and adjusts the volume. Since the amplified signal level is not large enough to sound the super-directional speaker 153 and the woofer speaker 155, the signal sent from the preamplifier 166 by the power amplifier 167 is used as the super-directional speaker 153 and the woofer speaker. Amplify so that sound can be output from 155.

Further, the preamplifier 166 is adapted to transmit and receive signals from the graphic equalizer 168.

When a flat speaker 156 is used instead of the super directional speaker 153, the modulation signal generation unit 162 and the high resolution sound source unit 163 are abolished as shown in FIG. 29.

Specifically, as shown in FIG. 30, the bench 152 is provided with a flat speaker 156 on the backrest portion 157 of the bench 152, and an elastic material such as PVC is provided on the surface side thereof. A cover cord 158 made of rubber or the like is provided. Further, at least for the skin of the backrest portion 157, an acoustically transparent mesh cloth is used.

As a result, the user can give a sense of presence even at a low volume by being directly wrapped in the sound from the back side behind it. Also, the person sitting on it can block the sound to some extent.

FIG. 31 is an explanatory view of a Goryo building showing an example of a sound generator 170 equipped with a sound extension function that expands opportunities for effective use of sounds around us by making it a room for reading by sound (hereinafter, also referred to as “Goryo”). Is.

The sound generator 170 can be used, for example, as a reading room. Reading aloud is very important, as it has been pointed out that it "revitalizes the body" and "leads to the power of the mind," but unfortunately the once prosperous reading culture is declining. ..

However, in recent years, not only the learning effect but also the medical effect has been recognized that it leads to activation of the brain, promotion of physical and mental health, elimination of so-called hikikomori, etc. while enjoying the rhythm, tempo and sound.

Individuals, friends, parents and children can enjoy reading aloud and regain their physical sensation by creating a dedicated "reading room" that has never been seen in a library. It is also possible to record one's own reading and use it as a sound generator.

In addition, reading aloud has been mainly performed for infants to elementary school children, but there are increasing opportunities to read aloud for elderly people who have difficulty seeing small letters. Demand for "read-aloud rooms" that emphasize voice clarity is expected to increase in the future.

In this way, by constructing a "read by sound" design and reading a book with environmental sounds in a reading space in a library or the like, it is possible to make a device that can deeply impress the person's monologue reading experience. .. In addition, the device has the effect of reading aloud to infants and the elderly, and boosting reading against young people's aliteracy, as well as sound devices and workshops focusing on expressions related to sounds in books and onomatope.・ It may be a sound education program.

The sound generator 170 can also be a room in which reading can be performed in an environment of one's favorite sound effect (Sound Effect).

Specifically, you can read quietly in the sound of rain, read while feeling the feeling of travel with the sound of the train, or read with the sound of the waves at the beach, as if you were reading at the beach. You can also select and stack multiple of them. You can also experience the experience of reading a book in front of the bonfire while playing the sound of the bonfire, and you can freely choose the season and place. Alternatively, you can choose sounds that are relevant to the theme or historical background of the book you are reading. This makes a deep impression of the person's unique reading experience.

Further, as an example of the sound generator, a room may be used to play a CD book for the visually impaired so that a slow and rich German writing experience can be enjoyed. At this time, it can also be provided with a function as a recording room for creating a CD book by volunteers and staff.

Therefore, as an example of the sound generator 170, it is possible to dare to make a quiet room close to silence.

Specifically, we provide a valuable space where you can experience reading in a free style (posture) in a quiet environment where noise (external sounds) are blocked and controlled. Further, at this time, a sound generated in the room (for example, a sound of turning a page) may be recorded and stored in a database, and may be intentionally sounded from a speaker or the like as an environmental sound.

Regarding the reverberation time (average sound absorption coefficient) in the above-mentioned five-ridged room, it is possible to set the sound to be arbitrarily ringed by referring to the reflection analysis of sound waves while considering the relationship between the center frequency and the reverberation sound. Is.

It is also possible to create an environment that awakens the sensibilities of the ears (sound art) by reminding the user of the sound without making a sound by using the five outer walls of the five-ridged room.

It can be said that Japanese is a special language that has more onomatopes than other foreign languages, and even now, new and unique onomatopes are being created.

In addition, there are cases where the characters themselves are visually designed and established as calligraphy or typography.

In addition, there are various onomatopes in foreign languages, and there are expressions different from those in Japan, such as the barking of animals.

Therefore, in addition to real sounds derived from nature or using nature, onomatopoeia, onomatopoeia, onomatopoeia, mimicry pictures, etc. expressed in books such as novels, poems, haiku, and comics are extracted (extracted) and created into a database. After that, it can be used as an installation such as projecting characters or figures on the wall surface or displaying them on a monitor, and displaying characters and patterns, or characters (lyrics) and scores.

When looking back on the sound environment in an existing library, there are few plans other than ensuring tranquility and establishing an audiovisual room, and except for those who personally listen to music with headphones or earphones, the facility " Designs related to "reading and sound" are considered unnecessary.

However, human senses are by no means separated, and while forming a complex perceptual network, they perceive various phenomena and are not unrelated to "reading" and "listening."

Therefore, with "reading and sound" as the dema, we can propose a pentagonal room with the following functions. It is not just an isolated soundproof room, but a space that ensures the clarity of the sound while ensuring an appropriate loudness (volume) inside, and at the same time as a room designed so that almost no sound leaks to the outside. There is.

The number of users is estimated to be about 1 to 8, and in order to create an optimum sound field on this scale, a pentagon is the most suitable because acoustic interference (fluttering) occurs in a normal quadrangle.

Further, as shown in FIG. 31, by setting one of the five surfaces of the inner wall of the sound generator 170 as the sound absorbing wall 171, the optimum sound resonance and diffusivity can be adjusted.

When one surface of the sound generator 170 is a sound absorbing wall 171, a movable sound absorbing curtain 172 may be further provided on the adjacent wall surface.

Further, it is desirable to arrange a sound absorbing material 173 such as glass wool and a rib portion 174 on the ceiling side of the sound generator 170 to control the bass range and to ventilate with the intake pipe 175 and the exhaust pipe 176. ..

FIG. 32 shows a water droplet sound generator 180 provided with a sound expansion function that expands opportunities for effective use of sounds around us by using liquid fertilizer in a device for plant cultivation.

In the water drop sound generator 180, a liquid fertilizer tank 182 is installed below the planter main body 181. The liquid fertilizer stored in the liquid fertilizer tank 182 is pumped up by a pump 183 and guided upward by a pipe 184 to extend in the height direction of the planter main body 181. Liquid fertilizer is dropped from a nozzle 186 arranged near the upper part of the pipe 185, and water drops are dropped on a sounding body 187 as a sound source portion provided at the lower part of the pipe 185 to make the dropped sound sound.

The planter main body 181 in the vicinity of the sounding body 187 is provided with an opening 181a for emitting the dropping sound from the inside of the planter to the outside.

The water droplets (liquid fertilizer) after the dropping are reduced to the liquid fertilizer tank 182 via the recovery pipe 188.

The material of the sounding body 187 as the sound source portion is preferably metal (for example, stainless steel) or ceramic, but other plastic, FRP, wood, cloth, paper, stone, etc. are also conceivable. At this time, the dripping sound has a sound pressure level of 45 to 50 dBA or more in a closed space, and is preferably in a range that can be sufficiently heard by the human ear.

The pipe 185 for dropping water droplets can be made of transparent acrylic so that the amount and movement of water can be visualized.

The dripping sound can be recorded through a microphone or the like (not shown) and stored in a database. Further, another sound may be superimposed on the dropping sound by the ringing of a speaker or the like (not shown).

Other industrial applicability

The present invention is not limited to the above embodiment, and various modifications can be made. For example, the dropping device 76 shown in FIGS. 14 and 5 has a plurality of hemispheres as shown in FIG. 33. A blade body 76c for diffusing water droplets is placed below the dropping body 76b (the number, height, and size of the dropping body 76b are arbitrary), or in the middle of the dropping body 76b made of a cylindrical deformed cylinder. A perforated plate 76e having a plurality of dropping holes 76d (the number, position, and diameter of the holes are arbitrary) is arranged, a screw having a smaller diameter is inserted into the hole, and water is inserted through a slight gap between the holes and the screws. Can also be dropped.

Further, when the sound transmission tube 116 shown in FIG. 21 is buried in the ground, as shown in FIG. 34, the sound transmission tube 116 is covered with an underdrain (not shown) or the like along the extending direction, and the sound transmission tube 116 is covered with an underdrain (not shown). It is also possible to provide fixing brackets 191 at a plurality of locations so that each fixing bracket 191 is supported via a hanger 192 (see FIG. 3) or a support bracket 193 (see FIG. 3).

In addition, although not explained one by one, the configurations shown in each example, for example, the design such that the sound transmitting tube is doubled, the sound transmitting tube is oriented vertically or horizontally, and the number and shape of sounding bodies are different. Changes and applications to other examples can be adopted as appropriate.

The sound system may be realized as an audio device, a workshop, or a sound education program that can be expanded. Through sound, sound that opens awareness to the surrounding environment and encourages people to think about it and green environmental education ̶ ̶ can nurture a spirit of compassion for greenery.

Today, toilets are visually beautiful and hygienic, but there are many sources of noise, such as the so-called flushing sound for muffling and the operating noise of air towels, and these noises are the toilet. It is always occurring inside.

Therefore, an audio device capable of alleviating these noises may be incorporated in a hand-washing device, a greening device, or the like and designed in the toilet.

Similarly, sports gym bathrooms, hot springs, saunas, etc. are visually beautiful and hygienic, but the various sounds of water that occur there are not designed and are often heard. Has been done.

Therefore, an audio device capable of consciously recognizing and listening to those water sounds may be designed.

Furthermore, it is possible to design a sound that "supports mental survival" of human beings. When you realize that the sound of water is the sound of the nutrient solution that gives life to plants, you will experience and experience the greenery there more vividly and vividly. By feeling that the plants are alive with the sound of running water that circulates in the nutrient solution, you can feel closer to the "life that is here" and sympathize with the power of greenery.

Not only functionality such as partitioning, but also beauty and uniqueness as an object can be combined. In addition, it is possible to add advice and design on the installation method, such as the layout that is most acoustically effective for the installation space. Furthermore, it is possible to create an original design that makes the best use of the characteristics of the space in which it is installed, which contributes to the space design.

At present, the operating noise of the pump in a normal hydroponic cultivation device becomes noise and worsens the sound environment, but the sound of the pump is muted and NC25

We are surrounded by sound beyond the familiar world with soundscape design that enables people to connect with the environment according to the environment, for example, as a permanent structure or building. Is done.
The idea was to use elements such as sound-making waves, wind, rain, and spring water in the field to provide a place for people to make creative contact with the global environment.

As one embodiment of the present invention, a sound system for a soundscape that connects sounds by a sound transmission tube in a space separated by a structure such as a wall or a distance may be characterized.

The sound produced by the air blown onto the pipe travels through the 40 m sound transmission tube 112 buried in the ground and reverberates in the hollow 114 deeply dug like a well below the bench 113. Then, the sound is expanded and reflected by the acoustic reflector 115 arranged at the bottom of the cavity 114, and the sound becomes like a wind blows through, and rises from under the bench 113.

Since this sound can be reverberated within a radius of about 5 m around the bench 113, unlike the clear tone of a musical instrument such as a flute, for example, the sound of the wind blowing through and the wind passing through. You can hear the rustling sound.

In this way, the sound generator 120 uses wind speed to sound the sounding body 126, and the impact sound can be recorded through a microphone or the like (not shown) and stored in a database. Further, another sound may be superimposed on the impact sound by the ringing of a speaker or the like (not shown).
