Description

  The present invention relates to a room that visualizes how much noise generated in a room of a building is in the adjacent space, and a wiring device that is a component of the room.

  Generally, sound generated in a space partitioned by a partition material such as a wall material or a floor material may be transmitted to an adjacent space through the partition material. That is, when the space where the sound is generated is a room such as a dwelling unit in a housing complex, a room that is a section in the house, or a room such as a soundproof room that forms a section in the room In addition, sound may be transmitted to an adjacent space, which is a space outside the room. When sound is transmitted to the adjacent space, it may become noise for a person in the adjacent space. Therefore, the sound transmitted to the person in the adjacent space is required to have a sound pressure level of 40 dB or less, for example.

  In order to solve this type of problem, various techniques for improving sound insulation in partition materials such as wall materials and floor materials have been proposed (see, for example, Patent Documents 1 and 2).

Japanese Patent Laid-Open No. 9-195490 JP 2007-205071 A

  However, the partition material which improves sound insulation has a problem that it is generally expensive. In addition, even in rooms with expensive partitioning materials that are said to be highly sound-insulating, there is generally no sound transmitted to the adjacent space, and noise may be generated in the adjacent space. There is.

  In addition, there are many people who have low awareness of noise generated from their rooms and who are not aware of the noise itself. On the other hand, there are also many people who care about whether the noise from the room is not disturbing the adjacent space.

  In the embodiment described below, a neighboring house in a dwelling unit of a housing complex is illustrated as an adjacent space, but a room in a housing unit of a housing complex or a room in a detached house, or a room such as a soundproof room installed in the room The technical idea of this embodiment can be applied. That is, the “adjacent space” means a house across walls and floors, a room that is a section in the house, an outer space of a section (such as a soundproof room) provided in the room, and the like. In short, the technique of the present embodiment can be applied when there is an adjacent space in a building. In the case of an apartment house, the adjacent space includes not only dwelling units adjacent on the same floor, but also dwelling units located either on the upper or lower side on different floors. Of the upper and lower floor units, the lower floor units are particularly important.

  Therefore, in the present embodiment, as illustrated in FIG. 1, a description will be given assuming a room 1a where noise is generated and rooms 1b and 1c where noise is transmitted. The room 1a is generated in the room 1a, a sound sensor 11 that monitors the sound generated in the room, a determination device 10 that determines whether the sound generated in the room 1a becomes noise to the other rooms 1b and 1c, and so on. And a display 12 as a notification device for notifying when the generated sound becomes noise to the other rooms 1b and 1c.

  That is, as will be described later, the determination device 10 analyzes the sound detected by the sound sensor 11 and evaluates how much the sound can be heard by people in the other rooms 1b and 1c. Furthermore, the determination apparatus 10 determines whether or not the sound generated in the room 1a can be heard as noise by people in the other rooms 1b and 1c. The display device 12 is a notification device for notifying the person in the room 1a of the determination result of the determination device 10, and the sound generated in the room 1a in the determination device 10 is given as noise to the people in the other rooms 1b and 1c. When it is determined that there is a possibility of being transmitted, this is notified. That is, by visualizing the generation of noise, it is possible to make the person in the room 1a notice the generation of noise from the room.

  As the indicator 12, an indicator lamp that only turns on and off, an indicator lamp that changes color, an indicator that displays characters and figures, a combination thereof, and the like can be selected. For example, it is possible to adopt a configuration in which a notification lamp is always turned off and is turned on when it is determined as noise. Alternatively, if a liquid crystal display with a backlight is used as a display for displaying characters, it is always non-displayed. It is possible to adopt a configuration for lighting.

  The determination result of the determination device 10 can be notified audibly by a notification sound or a voice message as a notification device, in addition to being visually notified by the display device 12. For example, when the determination device 10 determines that noise is generated, a configuration that outputs a beep sound or a configuration that notifies by a voice message can be employed.

  Hereinafter, the determination apparatus 10 will be specifically described. A microphone is used for the sound sensor 11. Any type of microphone may be used, but generally a capacitor type, a dynamic type, or a piezoelectric type is selected. Further, as the sound sensor 11, a vibration pickup using a piezo element or an acceleration sensor can be used as a microphone. In particular, when the impact sound on the wall 21 or the floor 22 of the room 1a is detected by using a vibration pickup or an acceleration sensor together with a microphone, the determination accuracy in the determination device 10 can be improved.

  The determination apparatus 10 is configured using a digital signal processing device selected from a microcomputer, a digital signal processor (DSP), a field programmable gate array (FPGA), and the like. That is, the output of the sound sensor 11 is subjected to analog-digital conversion, and the following processing is performed as a digital signal.

  As illustrated in FIG. 2, the determination device 10 includes a feature amount extraction unit 13 that extracts a required feature amount from the audio signal output from the sound sensor 11. The feature quantity extracted from the audio signal by the feature quantity extraction unit 13 uses the level of a specific frequency component, the amplitude of the audio signal, the waveform of the audio signal, and the like.

  If the level of a specific frequency component is used, it may be related to the cause of sound generation. When sound is generated by a specific event (for example, sound generated with acoustic emission due to destruction of an object), characteristic frequency components are included, so if you extract the level of a specific frequency component, In some cases, the cause of sound generation can be estimated. In general, the sound insulation performance and impact sound performance of wall materials and floor materials as partition materials for partitioning between adjacent spaces are dependent on frequency as shown in FIG. When estimating the quantity, using the level of the frequency component of the audio signal can improve the accuracy of the estimation.

  Since the amplitude of the audio signal corresponds to the volume of the sound, the volume of the sound transmitted to the adjacent space can be estimated by obtaining the amplitude of the audio signal. Furthermore, since the time change of the amplitude can be captured by obtaining the waveform of the audio signal, the type of sound generated in the room 1a can be classified into impact sound, continuous sound, intermittent sound, and the like.

  The feature quantity extracted by the feature quantity extraction unit 13 is input to the estimation unit 14. The estimation unit 14 estimates the degree to which the sound generated in the room 1a is transmitted to the other rooms 1b and 1c (actually, it can be heard by people in the rooms 1b and 1c). The estimation unit 14 classifies sounds generated in the room 1a into two types, and further divides the sound into a case where sound is transmitted to the room 1b on the same floor and a case where sound is transmitted to the room 1c on the lower floor. The degree to which a person in 1b and 1c can hear a sound is evaluated. That is, since there are two kinds of sounds and the rooms 1b and 1c to which the sound is transmitted are two rooms, the estimation unit 14 uses four kinds of models for sounds heard by people in the rooms 1b and 1c. To estimate.

  Here, the type of sound includes sound generated away from the wall 21 and floor 22 that defines the space of the room 1a (hereinafter referred to as “air sound”) and sound generated by contact with the wall 21 and floor 22 ( Hereinafter, this is assumed to be “solid sound”. In short, a sound generated away from the partition material that partitions the room 1a and the other rooms 1b and 1c is defined as an air sound, and a sound generated by contacting the partition material is defined as a solid sound. Air sounds are sounds caused by human voices, audio-visual equipment (AV equipment), electrical equipment such as vacuum cleaners and washing machines, musical instruments, water supply / drainage in bathrooms and toilets, and opening / closing of doors. The solid sound is a sound caused by a human action such as walking or exercising, an article falling, or the like. That is, most of the daily noise can be covered by air sound and solid sound.

  Four types of models are shown in FIGS. 4 and 5 show models related to the transmission of air sound, and FIGS. 6 and 7 show models related to the transmission of solid sound. 4 and 6 show models in which sound is transmitted to the other room 1b on the same floor through the wall 21, and FIGS. 5 and 7 show models in which sound is transmitted to the room 1c on the lower floor through the floor 22. Is shown. In each model, the sound transmission path is divided when the sound generated in the room 1a is heard by people in the other rooms 1b and 1c.

  As shown in FIG. 4, when the air sound N1 is heard by a person in the room 1b, the transmission path passes through the wall 21 through the space from the place where the air sound N1 occurs to the wall 21 in the room 1a. It divides | segments into the path | route which passes through the space from the wall 21 and the person who exists in the other room 1b. Also, as shown in FIG. 5, the transmission path when the air sound N1 is heard by a person in the room 1c is a path through the space from the place where the air sound N1 is generated to the floor 22 in the room 1a, the floor 22 Is divided into a route that passes through the space from the floor 22 to a person in the other room 1c.

  On the other hand, as shown in FIG. 6, the transmission path when the solid sound N2 is heard by a person in the room 1b is a path through the space from the place where the solid sound N2 occurs to the wall 21 in the room 1a, the wall 21 Is divided into a route that passes through the space from the wall 21 to a person in the other room 1b. Also, as shown in FIG. 7, the transmission path when the solid sound N2 is heard by a person in the room 1c is a path through the floor 22 from the place where the solid sound N2 is generated, and from the floor 22 to another room 1c. Divide it into a route that passes through the space to the person.

  Furthermore, since it is necessary to determine whether or not a person recognizes the transmitted sound as noise, regardless of the type of sound or the transmission route, human auditory characteristics are also considered in order to evaluate sound transmission. To do.

As shown in FIGS. 4 to 7, the transfer characteristic in the space of the room 1a is S1, the transfer characteristic in the space of the other rooms 1b and 1c is T, the transfer characteristic of the wall 21 is G1, and the transfer characteristic of the floor 22 is G2, H is the human auditory characteristic. Note that the transmission characteristic G1 of the wall 21 uses the sound insulation characteristic of the wall material shown in FIG. 3A, and the transmission characteristic G2 of the floor 22 uses the sound insulation characteristic of the floor material shown in FIG. 3B. The A characteristic is used as the human auditory characteristic. In each model shown in FIGS. 4 to 7, the sound Y that can be heard by people in the other rooms 1 b and 1 c can be expressed as follows.
Y = N1, S1, G1, T, H
Y = N1, S1, G2, T, H
Y = N2, S1, G1, T, H
Y = N2, G2, T, H
On the other hand, since the sound is transmitted through the space of the room 1a to the sound sensor 11 regardless of whether it is the air sound N1 or the solid sound N2, this transfer characteristic is S2. The characteristic of the sound sensor 11 is represented by M. In this case, the sound X detected by the sound sensor 11 can be expressed as follows in the model for the air sound N1 shown in FIGS.
X = N1, S2, M
In the model for the solid sound N2 shown in FIGS. 6 and 7, the sound X detected by the sound sensor 11 can be expressed as follows.
X = N2 / S2 / M
From the above relationship, the air sound N1 and the solid sound N2 can be represented by the following equations by using the sound X detected by the sound sensor 11, respectively.
N1 = X / (S2 · M)
N2 = X / (S2 · M)
Using this relationship, in each model shown in FIGS. 4 to 7, the sound Y that can be heard by people in the other rooms 1b and 1c can be expressed as follows.
Y = X (G1 · H / M) (S1 · T / S2)
Y = X (G2 / H / M) (S1 / T / S2)
Y = X (G1 · H / M) (S1 · T / S2)
Y = X (G2 / H / M) (T / S2)
Therefore, in any case, it can be expressed in the form of Y = k1, k2, and X. In the case of sound transmission to another room 1b on the same floor, k1 = G1 · H / M, and in the case of sound transmission to the room 1c on the lower floor, k1 = G2 · H / M. Further, k2 = T / S2 when the solid sound N2 is transmitted to the room 1c below the floor, but k2 = S1 · T / S2 under other conditions.

  Regarding the coefficient k1, the human auditory characteristic H and the characteristic M of the sound sensor 11 are known information, and the transmission characteristic G1 of the wall 21 or the transmission characteristic G2 of the floor 22 is known if the characteristic of the partition material constituting the room 1a is known. Can be treated as known information. In other words, the coefficient k1 can be handled as known information if the characteristics of the partition material constituting the wall 21 or the floor 22 are known. However, it is necessary to select which of the transfer characteristic G1 and the transfer characteristic G2 is used depending on whether the sound N1 or the solid sound N2.

  The coefficient k2 is information about the space, and is affected by the position of the sound sensor 11, the position where the sound is generated, the position of the person who listens to the sound, etc., but is set as a fixed value using an average value. But it is possible to get a guide. However, as with the coefficient k1, it is necessary to distinguish between the air sound N1 and the solid sound N2.

  From the above consideration, the estimation unit 14 is required to have a function of determining whether it is the air sound N1 or the solid sound N2, and information on the transfer characteristic G1 of the wall 21 and the transfer characteristic G2 of the floor 22 is required. Here, the transfer characteristics G1 and G2 are selected by the characteristic setting unit 15. That is, if the partitioning material used for the wall 21 or the floor 22 used in the room 1a is known when the determination device 10 is installed, the sound insulation characteristic of the partitioning material is a D value (sound insulation performance) as shown in FIG. Grade) and L value (impact sound performance grade). For example, if the D value is known, the frequency characteristic of the transmission loss of the wall material is known as the sound insulation characteristic, and if the L value is known, the frequency characteristic of the impact sound level of the flooring material is known as the sound insulation characteristic. Therefore, the estimation unit 14 stores the frequency characteristics corresponding to the D value and the L value shown in FIG. 3 as data, and the characteristic setting unit 15 stores the D value of the partition material used in the room 1a. Or the L value is selected and given to the estimation unit 14 so that the estimation unit 14 can determine the coefficient k1 described above.

  As the characteristic setting unit 15, either a mechanical switch such as a dip switch or a digital thumbwheel switch or a memory switch using a nonvolatile memory is used. If the characteristic setting unit 15 is a mechanical switch, the coefficient k1 corresponding to the room 1a can be determined using only the determination device 10. If the characteristic setting unit 15 is a memory switch, a device different from the determination device 10 is connected to the determination device 10 and the contents of the memory switch are written. In this case, the determination apparatus 10 needs an interface for connecting another apparatus. As another device, a computer that executes an appropriate program or a dedicated setting device can be used.

  When the design drawing of the building is available, using the information obtained from the design drawing, as shown in FIG. 8, at least one of the sound insulation performance class and the impact sound performance class is calculated by the computer 40 as another device. Is possible. Information obtained from the design drawing includes floor material specifications, floor slab specifications, radiation coefficient, sound absorption, radiation area, and the like. In addition, there are different flooring specifications such as a direct floor, a double floor, a mat direct stretch, and a combination of a floor material and a mat.

  Various programs (tools) for obtaining a sound insulation performance grade or an impact sound performance grade using such information obtained from the design drawing are known. The computer 40 calculates at least one of the sound insulation performance class and the impact sound performance class by using this kind of existing tool. In particular, when the design drawing is produced by CAD (Computer Aided Design), the computer 40 can obtain at least one of the sound insulation performance grade and the impact sound performance grade simply by reading the necessary data from the design drawing. it can.

  The sound insulation performance class and the impact sound performance class obtained by the computer 40 are set in the characteristic setting unit 15. Here, the determination apparatus 10 includes an interface 18 for connecting the computer 40, and the sound insulation performance class and the impact sound performance class obtained by the computer 40 are automatically set in the characteristic setting unit 15. If the determination device 10 does not have the interface 18 and the computer 40 cannot be connected, the sound insulation performance grade and the impact sound performance grade obtained by the computer 40 may be manually set in the characteristic setting unit 15. Instead of obtaining the sound insulation performance grade and the impact sound performance grade with another computer 40, the judgment device 10 is provided with a function for directly inputting information obtained from the design drawing, and the judgment device 10 calculates necessary information. Also good.

  Moreover, since the sound insulation performance grade and the impact sound performance grade are measured by Japanese Industrial Standards (JIS A-1417, A-1418), the sound insulation performance grades and the sound insulation performance grades are determined according to certain procedures defined by the Japanese Industrial Standards. At least one of the impact sound performance grade may be measured. The sound insulation performance grade and the impact sound performance grade based on the actual measurement are set in the characteristic setting unit 15 manually.

  By the way, in the Architectural Institute of Japan, as a “sound insulation performance standard of a building”, as shown in FIG. 9, as shown in FIG. The table is open to the public. The list in FIG. 9 is shown in “Sound insulation performance standards and design guidelines for buildings” edited by the Architectural Institute of Japan (1999).

  If this list is used, the standard of the sound insulation performance grade and the impact sound performance grade can be obtained on the basis of the actual feeling for each type of sound generated in the other rooms 1b and 1c (that is, adjacent spaces). That is, at least one of the sound insulation performance grade and the impact sound performance grade is obtained based on the type and actual feeling of the sound. The sound insulation performance grade and the impact sound performance grade determined in this way are set in the characteristic setting unit 15 by manual work.

  Furthermore, at least one of the sound insulation performance class and the impact sound performance class may be automatically obtained using the relationship shown in FIG. In this case, as shown in FIG. 10, the determination apparatus 10 is provided with an evaluation table 41 in which a sound insulation performance grade (D value) and an impact sound performance grade (L value) are associated with a combination of sound type and energy. . The specific contents of the evaluation table 41 are the same as the list shown in FIG. However, the evaluation table 41 assigns a small classification (each row in the “sound insulation class” column) relating to air sound and floor impact sound to the corresponding sound type, and the contents of each cell (mesh) are sound energy (sound Pressure). Therefore, if the type and energy of the sound are collated with the evaluation table 41, the sound insulation performance grade or the impact sound performance grade can be uniquely determined.

  In order to obtain the sound type and energy, the determination device 10 determines the sound detection device 42 that detects the sound generated in the rooms 1b and 1c (ie, adjacent spaces), and the sound type detected by the sound detection device 42. And a sound recognition device 43 for identifying and detecting sound energy. The sound detection device 42 may be shared by the sound sensor 11. The sound detected by the sound detecting device 42 is input to the sound recognizing device 43 and divided into appropriate time intervals as in the speech recognition technology, and frequency characteristics for each time interval are extracted using Fourier transform, wavelet transform, or the like. Is done. The type of sound is identified using the frequency characteristics (frequency component distribution) and the relationship with the adjacent time intervals. The sound recognition device 43 also detects the sound pressure of the sound detected by the sound detection device 42.

  The sound recognition device 43 collates the detected sound type and energy with the evaluation table 41 after detecting the sound type and energy by the above-described operation. Since the evaluation table 41 associates the sound type and energy with the sound insulation performance grade and the impact sound performance grade, the sound recognition device 43 collates the sound type and energy with the evaluation table 41 so that the sound insulation performance grade and At least one of the impact sound performance grade is required. At least one of the sound insulation performance class and the impact sound performance class obtained in this way is set in the characteristic setting unit 15. That is, at least one of the sound insulation performance class and the impact sound performance class set in the characteristic setting unit 15 is automatically set.

  When the sound insulation performance class is set in the characteristic setting unit 15, the estimation unit 14 determines the transfer characteristic using the frequency characteristic of the transmission loss according to the sound insulation performance class. Further, when the impact sound performance class is set in the characteristic setting unit 15, the estimation unit 14 determines the transfer characteristic using the frequency characteristic of the impact sound level according to the impact sound performance class.

  By the way, since a fixed value is used for the coefficient k2, if the D value or L value of the partition material is specified by the characteristic setting unit 15, the sound detected by the sound sensor 11 can be detected by using the above-described model in the estimation unit 14. It is possible to estimate the degree to which a person in the rooms 1b and 1c can hear. Here, the estimation unit 14 estimates the sound pressure by adding the levels for each frequency component in the audible frequency range.

  The sound pressure as the estimation result estimated by the estimation unit 14 is input to the determination unit 16. The determination unit 16 compares the sound pressure obtained by the estimation unit 14 with an appropriate threshold value to determine whether or not the sound that can be heard by people in the other rooms 1b and 1c is a sound pressure that can be felt as noise. This threshold value is appropriately set based on a value set by law or standard as an unpleasant noise level. In general, if it is 40 dB or less in a room, it is not particularly noticeable as noise. Therefore, the threshold value may be set based on this value. The threshold value can be a fixed value.

  However, the sound pressure perceived as noise differs between a period in which a relatively high level of ambient noise (background noise) exists and a period in which the background noise level is low. Therefore, when the background noise level changes according to the time zone, it is preferable to set a threshold value for each time zone. Alternatively, the background noise level may be obtained from the sound detected by the sound sensor 11, and the threshold value in the determination unit 16 may be changed according to the obtained background noise level.

  In the above configuration, the sound pressure is estimated regardless of the frequency distribution because the sound pressure is estimated by adding the levels for each frequency component in the audible frequency range. However, it is not only sound pressure but also factors such as frequency distribution and sound continuity that a person feels as noise. Therefore, in the estimation part 14 and the determination part 16, you may determine whether it is noise considering these elements.

  Here, whether or not a person recognizes ambient sounds as noise is also related to psychological factors. However, in order to make a noise determination based on a criterion that does not vary due to individual differences, the estimation unit 14 uses a physical quantity. Only information that can be measured (sound pressure, frequency distribution, continuity of sound, etc.). That is, the determination unit 16 determines whether the noise is based on only the physical quantity related to the noise estimated by the estimation unit 14.

  When the determination unit 16 determines that the noise is present, the display control unit 17 provides the display 12 with an output for notifying the noise. In response to the notification from the display control unit 17, the display device 12 presents that the sound generated in the room 1 a may be transmitted as noise to the other rooms 1 b and 1 c. Note that the determination unit 16 may classify the degree of noise into three or more levels instead of the two-level determination as to whether or not noise is generated. In this case, the display controller 17 also needs to generate an output to the display 12 so as to distinguish three or more stages. For example, the noise level is set to three levels of “large”, “medium”, and “small”, and the indicator 12 displays red when the noise level is “high”, yellow when the noise level is “medium”, and noise. When the level is “Small”, it may be turned off.

  In addition, there is a case where a person in the room 1a does not notice even if the display is performed immediately after the sound is generated when the notification is performed using the display device 12. In view of this, when displaying the occurrence of a sound as noise on the display device 12, it is desirable that the display content of the display device 12 be held in the display control unit 17. The display content can be held for a fixed time (maximum of about 1 minute). However, when sound is generated intermittently within a short time, the display time is updated even when the display 12 is displaying. Is desirable. For example, when the display for notifying the occurrence of noise is held for 30 seconds, the display content is held for another 30 seconds when it becomes necessary to notify the occurrence of the next noise 20 seconds after the start of display.

  The sound sensor 11, the determination device 10, and the indicator 12 described above can be appropriately separated and placed in the room 1a. For example, the sound sensor 11 and the determination device 10 can be housed in one container, and this container can be provided separately from the container of the display 12. In this case, a wired or wireless communication path is provided between the two bodies. This configuration is an example, and it is possible to select how the sound sensor 11, the determination device 10, and the display 12 are arranged in the room 1a.

  Below, the example which has arrange | positioned the sound sensor 11, the determination apparatus 10, and the indicator 12 to the container of a wiring appliance is demonstrated. Examples of the wiring apparatus include an outlet shown in FIG. 11A and a wall switch shown in FIG.

  The container body 30 is formed in a shape that can be attached to a mounting frame for wiring equipment (for example, a mounting frame defined in JIS standards). That is, the same structure as a switch or an outlet attached to a wall or the like using the mounting frame (not shown) is adopted for a part of the container body 30.

  In one surface of the container body 30 shown in FIG. 11A, a plurality of (two in the illustrated example) insertion ports 31 into which plug blades of a power plug are inserted open. Hereinafter, the one surface where the insertion port 31 opens in the container 30 is referred to as the front surface of the container 30. The sound sensor 11 described above and a lamp cover 32 incorporating a light source (not shown) are arranged on the front surface of the container body 30. The light source and the lamp cover 32 constitute the display 12. As described above, the sound sensor 11 and the display device 12 are arranged in the container body 30. In addition, the determination device 10 is disposed inside the container body 30.

  The lamp cover 32 is made of a translucent material colored in a conspicuous color (yellow, orange, red, etc.). The material forming the lamp cover 32 may be opaque or transparent, but in the case of being transparent, a prism is formed at a site where light is transmitted in order to improve visibility. It is desirable to use a light emitting diode as the light source disposed inside the lamp cover 32. Further, a part of the light emitting diode package may be exposed on the front surface of the container 30 without providing the lamp cover 32.

  The container 30 shown in FIG. 11B includes a switch operation handle 33. The operation handle 33 has a configuration known as a so-called piano handle type operation handle. The operation handle 33 has a left end attached to the body 30 so that the right end can be pushed in. Similar to a wall switch such as a seesaw switch, this switch can be used for applications such as lighting on / off. Further, each time the operation handle 33 is pushed, the contact open / close state is reversed.

  The sound sensor 11 described above is provided on the front surface of the container 30 shown in FIG. 11B, and the lamp cover 32 is disposed above the operation handle 33. The lamp cover 32 constitutes the display device 12 together with a light source (not shown) similarly to the lamp cover 32 shown in FIG. Other configurations are the same as those shown in FIG.

  As the wiring apparatus, in addition to the power outlet and wall switch as described above, an information outlet including a coaxial connector and a modular jack, a ceiling rosette for attaching a lighting apparatus, and the like can be used. In addition, the configuration described in this embodiment can be incorporated in an intercom, a fire alarm, or the like. If it is a fire alarm capable of outputting a voice message, it is possible to notify that a noise is generated as a voice message. When the sound sensor 11 and the display device 12 are separated, the sound sensor 11 may be incorporated in a ceiling panel or a floor, and a display device such as an interphone may be used as the display device 12.

  Alternatively, storage furniture composed of unitized boxes and doors, or panel furniture that can be attached to a flat-screen TV, etc., by standing a pair of columns between the floor and the ceiling, You may provide the sensor 11, the determination apparatus 10, and the indicator 12. FIG. This type of furniture is a facility constituting the room 1a. Furthermore, the sound sensor 11, the determination device 10, and the display device 12 may be provided by being dispersed in these facilities and a device such as a wiring device or a fire alarm.

  As described above, the sound sensor 11, the determination device 10, and the display device 12 can be provided in the room 1a as one member constituting the room 1a by providing the sound sensor 11, the determination device 10, and the display device 12 integrally with the device body 30 of the wiring apparatus.

  In the above example, it has been described that it is determined whether or not the sound generated in the room 1a is transmitted as noise to the other rooms 1b and 1c. However, the room 1a can be replaced with the other rooms 1b and 1c. is there. That is, the sound sensor 11, the determination device 10, and the display device 12 can be provided in the other rooms 1b and 1c.

  In the configuration example described above, the case of distinguishing between air sound and solid sound has been described, but since the purpose is to visualize whether or not noise is generated, it is handled without distinguishing between air sound and solid sound. It is also possible.

  For example, when an impact sound is generated on the floor 22, it may be transmitted as a solid sound to the lower room 1c, or may be transmitted as an air sound to another room 1b on the same floor, and further, an air sound is transmitted to the lower room 1c. May also be transmitted. Therefore, using both the transfer characteristic G1 of the wall 21 and the transfer characteristic G2 of the floor 22, it may be estimated and judged how the sound is transmitted to each of the rooms 1b and 1c. In this case, it is considered unnecessary to distinguish between the air sound and the solid sound.

  Moreover, it is also possible to adopt a configuration in which only one of air sound and solid sound is monitored. Furthermore, although the noise is evaluated for both the other room 1b on the same floor as the other room and the other room 1c on the lower floor, a configuration may be used in which the noise for only one of the rooms is evaluated. For example, since the downstairs room 1c does not exist on the first floor of the apartment house, only the noise to the other room 1b on the same floor may be considered.

  In the configuration described above, a fixed value is used for the coefficient k2. However, when there are a plurality of sections in the room 1a, the sound sensor 11 is provided for each section, and the coefficient k2 is obtained for each section. Good. The coefficient k1 is also determined using the sound insulation performance of the wall 21 and the impact sound performance of the floor 22. However, the coefficient k1 can also be determined based on actual measurement in order to include the transmission of sound by the structural body. Alternatively, since the sound insulation performance of the partition member may change in the actual environment, the coefficient k1 may be determined based on a value measured after the construction. For example, in the housing performance display system (enforced in 2000), the display of the sound insulation characteristics of the walls 21 and the floor 22 is recommended. Therefore, using the displayed sound insulation characteristics provides more reliable post-construction characteristics. It is done.

  Furthermore, in the structure which isolate | separates the sound sensor 11 and the indicator 12, when the some sound sensor 11 is provided and the relationship of the sound pressure level detected by each sound sensor 11 in the estimation part 14 is used, a sound generation position And the size can be estimated. That is, by using the sound generation position and magnitude, the coefficient k2 can be set dynamically, and the accuracy of estimating the influence of noise on the other rooms 1b and 1c can be improved. Further, a plurality (preferably three or more) of sound sensors 11 are arranged in one place, and the arrival direction of the sound wave is estimated from the time difference at which each sound sensor 11 detects the sound, and any sound is detected. The distance relationship can also be estimated by analyzing the reverberation component of the sound detected by the sensor 11. In this configuration, it is desirable that the plurality of sound sensors 11 be arranged in an array on one plane.

  Below, the operation example of the judgment apparatus 10 is divided into an air sound and a solid sound (mainly a sound due to an impact on the floor). Further, it is assumed that three or more sound sensors 11 are provided and the distance to the place where the sound is generated can be estimated. Moreover, below, the case where the degree to which the sound generated in the room 1a is transmitted to the other rooms 1b and 1c is shown as an example.

  FIG. 12 shows an operation example of the determination device 10 when the sound generated in the room 1a is an air sound. The estimation unit 14 first obtains the distance from the output of the sound sensor 11 to the sound generation source (S11). At this point in time, the determination device 10 does not determine whether the sound received by the sound sensor 11 is an air sound or a solid sound, so the process for the air sound and the process for the solid sound are performed in parallel. However, FIG. 12 shows only processing for air sound.

  The estimation unit 14 estimates the sound pressure at the place where the sound is generated using the obtained distance and the sound pressure detected by the sound sensor 11 (S12). The sound pressure at the place where the sound is generated can be estimated by using a linear regression equation obtained by measuring in advance the relationship between the distance for each frequency component (frequency band) and the attenuation characteristic of the sound pressure.

  Next, the estimation unit 14 estimates the sound pressure received by the wall 21 and the floor 22 by using the sound pressure at the sound generation location and the distance from the boundary surface of the room 1a (such as the wall 21 and the floor 22). (S13). Furthermore, the estimation unit 14 uses the frequency characteristics (sound insulation performance) of the equivalent loss obtained from the sound insulation performance grade of the members constituting the boundary surface and the sound pressure of the obtained boundary surface, and applies them to the above-described model, The frequency characteristics of the sound transmitted to the other rooms 1b and 1c are estimated (S14). Here, the sound insulation performance obtained from the sound insulation performance grade is stored in the characteristic setting unit 15.

  When the frequency characteristics of the sound transmitted to the other rooms 1b and 1c are estimated as described above, the determination unit 16 determines whether or not the sound is noise by comparing with the known M ′ curve. (S15). Here, in order to apply the M ′ curve, background noise information (level and time zone) is required. Therefore, the background noise information may be obtained by measuring the background noise in the rooms 1b and 1c in advance, Apply residential area information established by the Ministry.

  FIG. 13 shows an operation example of the determination apparatus 10 when the sound generated in the room 1a is a solid sound. Similarly to the case of air sound, the estimation unit 14 obtains the distance from the output of the sound sensor 11 to the sound source (S22). By the way, the feature quantity extraction unit 13 extracts feature quantities such as frequency component levels, amplitudes, and waveforms from the audio signal output from the sound sensor 11. The estimation unit 14 uses the feature amount extracted by the feature amount extraction unit 13 to estimate whether the sound received by the sound sensor 11 includes a sound generated by an impact (S21). Further, the estimation unit 14 estimates whether the object that generated the solid sound is a heavy object or a light object from the frequency component, the duration, and the like.

  As in the case of air sound, the estimation unit 14 estimates the sound pressure at the place where the sound is generated using the obtained distance and the sound pressure detected by the sound sensor 11 (S23). The sound pressure at the place where the sound is generated can be estimated by using a linear regression equation obtained by measuring in advance the relationship between the distance for each frequency component (frequency band) and the attenuation characteristic of the sound pressure.

  Next, the estimation unit 14 estimates the acceleration when the object that generated the solid sound collides with the boundary surface (wall 21 or floor 22) (S24). The acceleration can be estimated by using a linear regression equation obtained by measuring in advance the relationship between the sound pressure, the decay time, and the acceleration at the sound generation location. The acceleration may be estimated by calculating the impact force from the sound pressure at the sound generation location and using the impact force and the floor impedance.

  Further, the estimating unit 14 uses the frequency characteristics (impact sound performance) of the equivalent loss obtained from the impact sound performance class of the members constituting the boundary surface and the estimated acceleration, and applies them to the above-described model to The frequency characteristics of the sound transmitted to the rooms 1b and 1c are estimated. Here, the impact sound performance determined by the impact sound performance grade is stored in the characteristic setting unit 15.

  However, in the illustrated example, instead of using the impact sound performance grade, a linear regression equation is set by measuring in advance the relationship between the estimated acceleration and the sound pressure transmitted to the other rooms 1b and 1c. In this case, the estimation unit 14 estimates the sound pressure transmitted to the other rooms 1b and 1c by substituting the estimated acceleration into this linear regression equation (S25). That is, the calculation amount in the determination apparatus 10 can be greatly reduced.

  As described above, when the sound pressure when the solid sound generated in the room 1a is transmitted to the other rooms 1b and 1c is estimated, the determination unit 16 compares the sound pressure with a known M ′ curve. It is determined whether or not it is noise (S26).

  The configuration example described above employs a configuration in which the sound input from the sound sensor 11 is displayed on the display 12 that is a notification device when the determination unit 16 provided in the determination device 10 determines that the sound is noise. This operation can be used when noise is generated in a situation where the display 12 can be seen, but it is not possible to know that noise has occurred in a situation where the display 12 cannot be seen. Can not. For example, when a child who is on the answering machine while the parent is out is playing in the room 1a, it cannot be confirmed whether or not a sound that causes noise in the other rooms 1b and 1c was generated.

  In order to cope with such a situation, as shown in FIG. 14, the determination device 10 is provided with a storage unit 44 that stores the date and time when the sound determined by the determination unit 16 is determined as noise together with the determination result as a history. May be adopted. The history stored in the storage unit 44 can be displayed on the display 12 by operating an operation unit (not shown) provided in the determination device 10.

  In addition, when the storage unit 44 is configured by a memory card that can be attached to and detached from the determination device 10, the storage unit 44 is removed, and the storage unit 44 is attached to another device such as a computer. The history may be read by the apparatus. Alternatively, an appropriate communication unit (interface) may be provided in the determination device 10 and the history stored in the storage unit 44 may be read by another device that can communicate with the determination device 10.

  By providing the storage unit 44, it is possible to confirm whether noise has been generated after the noise has been generated even in a situation where the display device 12 cannot be seen when the noise is generated. In order to indicate whether or not the noise generation history is stored in the storage unit 44, when the noise generation history exists, a display indicating that fact may be displayed on the display unit 12. Good.

  Since the noise generation history is stored in the storage unit 44 in this manner, it is possible to cope with noise generation. For example, when a child is generating noise while the parent is away, it is possible to form an environment in which the child can spend time in the room 1a, thereby suppressing noise generation. Alternatively, it is possible to take measures such as generating a mosquito tone or a dissonance so that the child leaves the room 1a.

  The determination device 10 is not limited to being used alone in the room 1a, but may include a communication unit 45 that communicates with other devices as shown in FIG. That is, it is preferable that the communication unit 45 has a function of notifying a determination result to another outdoor device via a communication network. The specification of the communication unit 45 is not particularly limited. For example, when a LAN interface is used as the communication unit 45, the determination device 10 and other devices are used by using a wide area communication network such as an indoor communication network of an apartment house or the Internet. Communication with is possible.

  If the determination device 10 includes the communication unit 45, for example, when the room 1a is a dwelling unit of a housing complex, the management of the determination device 10 and the manager room is performed using the local communication network 46 laid in the housing complex. Communication with the device 47 can be enabled. If the management device 47 and the determination device 10 can communicate with each other, it is possible to use information notified from the determination device 10 to the management device 47 as evidence when a noise problem in a collective housing occurs. Become. Since the management device 47 is not disposed in the room 1a, evidence from a third party can be obtained and an objective determination can be made.

  The management room is an example of the arrangement location of the management device 47. The management device 47 that receives the determination result from the communication unit 45 of the determination device 10 via the communication network is provided outside the apartment house, and the management device 47 May be operated by a third party who has contracted with the management association of the housing complex. Here, only the result of determination by the determination device 10 is notified to the management device 47, and the sound output from the sound sensor 11 is not notified, so privacy is maintained.

  In the above-described operation, the function of visualizing the generation of noise by using the determination device 10 has been described. However, when the generation of noise is detected by the determination device 10, the device that reduces the influence of noise is operated. It may be. As a device for reducing the influence of noise, a device that constantly generates background noise is known.

  The noise targeted by this embodiment is not stationary noise but temporarily generated noise such as speech or impact sound. For this type of noise, background noise of the same quality as the noise is used. By generating it constantly, the possibility of being recognized as noise is reduced. This kind of background noise is called masking sound in the sense that noise masking is performed.

  In order to reduce the influence of noise in the rooms 1b and 1c when noise is generated in the room 1a, as shown in FIG. 16, a sound generator 50 that generates a masking sound is placed in the rooms 1b and 1c (adjacent spaces). It is preferable to arrange. The sound generator 50 includes a speaker and a signal generation circuit that outputs a masking sound from the speaker. The signal generation circuit is configured by using a DSP (Digital Signal Processor) or the like, and generates a signal having the same sound quality (similar waveform) as noise that does not have meaning by synthesizing sampling sounds. Moreover, you may make it output the background noise which adjusted the phase so that at least one part of noise may be canceled as a masking sound.

  The sound generator 50 can be operated continuously. In this case, background noise is always generated, and depending on the time of day, the sound generator 50 is a factor that generates noise. . Therefore, it is preferable to use the communication unit 45 (see FIG. 15) of the determination device 10 to instruct the sound generation device 50 from the determination device 10 to generate a masking sound.

  For example, if the determination device 10 instructs the sound generation device 50 to generate a masking sound while a sound determined to be noise by the determination device 10 is generated, the masking is performed only during the noise generation period. Sound will be generated. This operation is suitable when using background noise whose phase is adjusted so as to cancel at least part of the noise as the masking sound.

  However, depending on the type of masking sound, if background noise is generated only during the period of noise generation, the sound pressure of the noise may increase. Therefore, a noise learning device 51 that learns the time zone in which the sound judged to be noise by the judgment device 10 is provided, and the masking sound is generated from the sound generation device 50 in the time zone learned by the noise learning device 51. Also good.

  The noise learning device 51 stores a history in which a sound type and a time zone in which the sound is generated are associated with each other for the sound determined to be noise by the determination device 10, and noise may be generated using the history. It has a function that requires a high time zone. For example, when the above-described history is accumulated and the frequency at which noise is generated is obtained for each time zone, a time zone where the possibility of noise generation is high can be obtained. The noise learning device 51 gives an instruction to the sound generation device 50 to generate a masking sound in a predetermined time zone including a time zone in which there is a high possibility of noise.

  In this case, if the same masking sound is generated in a time zone in which noise is not generated and a time zone in which noise is generated, the masking sound may become noise. Therefore, it is preferable to make the masking sound different between the period in which the noise learning device 51 instructs the sound generator 50 to determine that the noise is determined by the determination device 10 and the other period.

  When the determination device 10 is provided in each of the rooms 1a, 1b, and 1c of the apartment house, the sound generation device 50 and the noise learning device 51 may be provided integrally with the determination device 10. In this case, if it is possible to communicate with each other between the determination apparatuses 10, when noise occurs in any of the rooms 1a, 1b, 1c, the determination apparatus 10 is integrated with the determination apparatus 10 in the other adjacent rooms 1a, 1b, 1c. The sound generator 50 provided in the above can be operated to suppress noise.

  As described above, the determination device 10 may be provided in the container 30 of the wiring device, or may be provided with a plug blade so that the determination device 10 can be plugged into an outlet. In addition, in a door phone parent device including a connector for connecting an external device such as a sensor, the determination device 10 may be connected as an external device. Alternatively, the determination device 10 or the determination device 10 and the sound generation device 50 may be provided as a part of the function of a device such as a television receiver or an audio device, or a musical instrument such as an electronic piano.
