Description

  The present invention relates to an acoustic surface material arrangement system, a wall surface storage unit, and a partition panel that enhance acoustic effects in a living room.

  In general, in a space where the opposing surfaces are parallel and reflective, such as a floor surface and a ceiling surface, it is known that sound is reflected multiple times between the parallel surfaces and causes flutter echo. For this reason, when the spatial shape is rectangular in plan view or when the ceiling surface is flat, flutter echo occurs between the opposing surfaces, which adversely affects the acoustic environment. Therefore, in order to prevent the occurrence of such flutter echoes, a method is adopted in which the wall surface is formed into a folded wall shape, or the ceiling surface is inclined so as not to be parallel to the floor surface.

  Also, in recent years, in buildings such as private houses, there has been a growing demand for rooms that place importance on the acoustic environment such as audio rooms, listening rooms, home theaters, and musical instrument practice rooms. There is a tendency for acoustic design to be effective.

  In response to such demands, especially when installing a room with sound equipment in a house, it is necessary to prevent the sound from leaking out of the room or causing vibrations. A high level of sound insulation is required to ensure a quiet environment. In addition, in the living room, it is required to appropriately design the sound so that the sound does not reverberate or generate a reflected sound.

However, if the wall surface is a folded wall shape on a residential scale, the wall thickness will increase and the living space will be narrowed. For acoustic measures, perforated boards with many sound absorbing holes in the flat plate will be used as the wall material. There were many examples to use as. For example, Patent Document 1 discloses an acoustic adjustment panel having a configuration in which a concave and convex portion that is continuous over the front surface is provided to form an uneven panel body, and a number of sound absorbing openings are provided at the bottom of the concave portion of the panel body. Are listed.
Japanese Patent Laid-Open No. 5-51981

  However, considering sound absorption, the perforated boards, the panel body having unevenness, and the like have a defect that only sound near the resonance point of the plate material is absorbed. In addition, fibrous materials and porous materials do not have sufficient sound absorbing performance in the low frequency range, and are not suitable as sound absorbing materials for the entire band. In other words, in order to effectively design the sound, not only the sound absorbing material, but also a reflecting material having a low sound absorbing characteristic is arranged to adjust the ratio of sound absorption and reflection, and the sound absorbing material can absorb sound up to the low frequency range. In addition, it is necessary to partially install a sound absorbing material that absorbs sound in the mid-high range so that the sound is distributed uniformly throughout the room.

  However, such adjustment of sound absorption and reflection is very difficult, and although it is possible to calculate a high characteristic by calculation, in practice, various environmental conditions overlap and it is partially It is difficult to obtain an ideal diffuse sound field, for example, resulting in a problem that much design time and cost are required.

  In addition, the interior of the room using the boards and the panel body having an uneven shape has a drawback that the atmosphere is monotonous and lacks in design.

  Therefore, the present invention has been made in view of the above-described problems, and is an acoustic surface material that can be easily applied to an acoustic design having excellent acoustic characteristics over a wide frequency band and can be applied with improved design. To provide a storage unit and a partition panel that can construct a placement system and efficiently perform acoustic design, have excellent designability and versatility, and can secure a high acoustic effect. It is aimed.

  In order to achieve the above-described object, an acoustic surface material arrangement system according to the present invention includes a sound absorbing surface including a sound absorbing material and having a high sound absorbing characteristic, and a reflecting surface including a reflective material and having a low sound absorbing characteristic. Are alternately arranged in the horizontal direction along the wall surface of the living room.

  For rooms with good acoustic effects, it is important to adjust the sound absorption and reflection so that the sound is distributed uniformly, but according to the configuration of the present invention, the sound absorption surface and the reflection surface are alternately arranged. By arranging, acoustic design can be easily performed while ensuring a certain acoustic effect.

  Further, in the acoustic surface material arrangement system, in consideration of the sound range to be particularly enjoyed, a plurality of sound absorbing surfaces and reflecting surfaces are arranged, and the ratio of the area of the sound absorbing surface to the wall area of the room is the sound reflection. It may be set to 20 to 30% in a room where the tendency is increased, and 70 to 80% in a room where the sound absorption tendency is increased.

  According to this, in a room with a high tendency to reflect sound, standing waves can be eliminated, and musical instruments such as percussion instruments and movies can be enjoyed live in a firm low range, and the sound absorption tendency can be improved. The raised rooms can produce lively sounds, and can be made suitable for enjoying the spread of classic sounds and good localization, such as playing musical instruments such as strings and woodwinds, or vocal music.

  The sound absorbing surface and the reflecting surface are preferably arranged so that the sound absorbing surfaces or the reflecting surfaces do not face each other between the opposing wall surfaces.

  Thereby, it is possible to suppress the occurrence of acoustic disturbance such as flutter echo and obtain a good acoustic effect.

  Further, in the wall surface storage unit of the present invention, a sound absorbing door having a height from the floor to the ceiling and having a high sound absorbing property formed on the front surface of the storage portion including the sound absorbing material, and a reflective material. The reflective doors having low sound absorption characteristics formed in a manner are arranged alternately in the horizontal direction.

  With such a configuration, sound absorption and reflection can be arranged in an appropriate balance to achieve a preferable sound, and the storage portion can function as an air layer to further enhance the acoustic effect.

  In the wall storage unit, one of each of the sound absorbing door and the reflecting door, or two of the sound absorbing door and the reflecting door are combined as a pair of doors, and a plurality of pairs of doors are attached in a folding door shape. preferable.

  According to the present invention, it is possible to easily perform acoustic design in accordance with a sound range desired to be enjoyed by adjusting the arrangement of sound absorption and reflection, and it can also be used to prevent acoustic disturbance such as flutter echo.

  Further, the partition panel of the present invention includes a plurality of sound absorbing surfaces having a high sound absorbing characteristic formed by including a sound absorbing material and a plurality of reflecting surfaces having a low sound absorbing characteristic formed by including a reflective material. It is characterized by being alternately arranged in the direction.

  It is preferable that the adjacent sound absorbing surface and the reflecting surface are bent and disposed, and the sound absorbing surface and the reflecting surface are connected to each other so as to be rotatable, and are foldable. It may be a configuration.

  By arranging the partition panel with such a configuration in the room, it is possible to easily construct a room to which the acoustic surface material arrangement system is applied, and the influence on the acoustic environment due to the openings and fittings in the room is reduced. Therefore, it is possible to achieve an appropriate acoustic design and obtain a high acoustic effect.

  Hereinafter, the best mode for carrying out an acoustic surface material arrangement system, a wall surface storage unit, and a partition panel according to the present invention will be described with reference to the drawings.

<Acoustic face material placement system>
1 to 3 are plan views showing examples of living rooms to which the acoustic surface material arrangement system of the present invention is applied.

  In the acoustic surface material arrangement system according to the present invention, the sound absorbing surface 3 including a sound absorbing material and having a high sound absorbing property and the reflecting surface 4 including a reflective material and having a low sound absorbing property are provided on the wall surface of the living room 1. Are arranged alternately along the horizontal direction.

  The sound absorbing surface 3 is, for example, a fabric made of polyester fiber fabric or the like at least on the surface side (inner side outer peripheral surface) of a base material in which a wooden frame framed in a rectangular shape is filled with a fibrous sound absorbing material such as glass wool or rock wool. A panel body can be used by covering with. As the sound absorbing material to be filled in the wooden frame, any material can be used as long as it is a porous sound absorbing material such as flexible urethane foam, aluminum foam, ceramic foam, etc. in addition to the above-mentioned fibrous sound absorbing material. it can.

  In addition, as the reflective surface 4, a heat insulating material is filled in a rectangular shaped decorative wood, a solid material such as solid wood, a stone material such as marble, a plate material such as a glass material, or a wooden frame shaped like a rectangular shape. It is possible to use a panel body obtained by coating the surface of the substrate with a cloth.

  The sound absorbing surface 3 and the reflecting surface 4 are each provided in plural numbers along the wall surface of the living room 1. Further, the ratio of the area of the sound absorbing surface 3 to the wall area of the living room 1 is changed between a room where it is preferable to suppress the tendency of sound absorption by relatively increasing the reflection tendency of sound and a room where it is preferable to increase the sound absorbing tendency. It is supposed to be arranged.

  In other words, it is better to eliminate standing waves in the low frequency range and to have a slightly higher reflectivity and moderate reflection, so you want to enjoy live performance in percussive instrument performances and movies in a solid low frequency range. In that case (live), the reflection tendency of the sound in the living room 1 is increased, and the area of the sound absorbing surface 3 with respect to the wall area is arranged at a ratio of 20 to 30%. More preferably, the ratio of the sound absorbing surface 3 is an area ratio of 25%.

  FIG. 1 shows an example in which the proportion of the sound absorbing surface 3 is about 25% with respect to the entire wall area of the living room 1. The sound absorbing surfaces 3 are arranged along the wall surface 2a on both sides of the opening 11 arranged in the upper part in the drawing. Here, since the opening 11 is fitted with a glass shoji, it functions as a reflecting surface.

  Further, on the wall surface 2b near the entrance / exit 12 facing the wall surface 2a with the opening 11, the sound absorbing surface 3 and the reflecting surface 4 are alternately arranged along the wall surface 2b and separated from the wall surface 2b by about 10 cm. Has been placed. This space acts as an air layer and enhances sound absorption and sound insulation with the adjacent room.

  Thereby, in the living room 1 of the figure, the sound absorbing surface 3 and the reflecting surface 4 are alternately arranged on the wall surface 2a having the opening 11 and the wall surface 2b opposite to the wall surface 2a, and the sound absorbing surfaces 3 and The reflecting surfaces 4 are arranged so as not to face each other. In addition, on the left and right wall surfaces 2c in the figure, the two sound-absorbing surfaces 3 are shifted in the horizontal direction so that the sound-absorbing surfaces 3 do not face each other.

  By arranging the sound absorbing surface 3 and the reflecting surface 4 in this way, the tendency of sound reflection in the living room 1 can be made relatively high and the sound absorbing tendency can be suppressed, thereby forming the living room 1 suitable for the low sound range. can do.

  On the other hand, because it is said that vibrant sounds can be obtained in the high range, if you want to enjoy the expanse of classic sounds and good localization, such as playing musical instruments such as stringed and woodwind instruments, or vocal music (dead) The sound absorbing tendency in the living room is increased, and the area of the sound absorbing surface 3 with respect to the wall area is arranged at a ratio of 70 to 80%. More preferably, the ratio of the sound absorbing surface 3 is set to an area ratio of 75%.

  FIG. 2 shows an example in which the ratio of the sound absorbing surface 3 is arranged to be about 75% with respect to the entire wall area of the living room 1. In the living room 1 as well, since the opening 11 acts as a reflecting surface, the sound absorbing surfaces 3 are respectively disposed on the wall surfaces 2 a on both sides of the opening 11. On the wall surface 2b facing the wall surface 2a, the reflecting surfaces 4 are arranged on both sides, and the sound absorbing surface 3 is arranged in the center. The sound absorbing surfaces 3 and the reflecting surfaces 4 are alternately arranged on the wall surface 2c. Since the door of the entrance / exit 12 acts as a reflecting surface, the sound absorbing surface 3 is disposed at a position facing the entrance / exit 12 of the wall surface 2c.

  As a result, the ratio of the sound absorbing surfaces 3 is secured to about 75%, and the sound absorbing surfaces 3 and the reflecting surfaces 4 do not face each other between the opposing wall surfaces. As a result, the sound absorption tendency in the living room 1 can be increased, and the living room 1 suitable for the high sound range can be formed.

  Furthermore, in the living room 1 illustrated in FIG. 2, the sound absorbing surface 3 and the reflecting surface 4 are spaced apart from the wall surfaces 2a, 2b, and 2c by about 10 cm to form an air layer. Thereby, it is comprised so that the external noise is interrupted | blocked, the quietness in the living room 1 is maintained, and the sound generated in the living room is not leaked to the outside.

  Further, when it is desired to enjoy an intermediate sound range, that is, playing a musical instrument such as a brass instrument, a piano, or an electric tone, or an audio sound (neutral), the ratio of the sound absorbing surface 3 is preferably set to an area ratio of 50%.

  FIG. 3 shows an example in which the ratio of the sound absorbing surface 3 is arranged to be about 50% with respect to the entire wall area of the living room 1. Further, in the example of the figure, the living room 1 includes a front room 13. Also in the living room 1, the sound absorbing surfaces 3 and the reflecting surfaces 4 do not face each other between the opposing wall surfaces 2d and 2d, and the living room 1 suitable for the intermediate sound range is formed.

  In the illustrated embodiment, it is desirable that the sound absorbing surface 3 and the reflecting surface 4 are respectively formed at substantially the same height as the height from the floor surface to the ceiling surface of the living room 1. Thereby, the difference in the surface finish of the sound absorbing surface 3 and the reflecting surface 4 brings the contrast in the room, and the interior property can be enhanced.

  In addition, in the living room 1 that employs the acoustic surface material arrangement system as described above, if an attempt is made to more effectively plan the sound, the ceiling surface is finished using a sound absorbing ceiling finishing material such as a rock wool sound absorbing material. It is desirable.
