  As is well known, the anechoic chamber described with reference to FIGS. 22 and 23 can be configured to have extremely high acoustic characteristics. However, the construction cost is extremely expensive and the room is narrow. There are places in the house that are difficult to apply.

  In recent years, there has been an increasing demand for a sound room that can use a narrow living space widely and has a construction cost that is not so high and that has a certain level of sound effect. A sound diffusing plate is used as an acoustic adjustment member having a concavo-convex shape on the surface made of a quality material. This sound diffusing plate, after placing it on the wall or wall and ceiling of the acoustic room or the corner of the wall and wall, variously investigated the arrangement conditions, and after examining the place that seems to be appropriate in acoustic design, It is used by firmly bonding and fixing to walls and corners.

  The above is a sound improvement method for enhancing the sound effect in order to hear good sound in a conventional sound room such as a listening room or a music hall. However, these sound improvement methods can be attached with an acoustic adjustment member. The sound adjustment member may be bonded to the corner or wall or ceiling with a sufficiently strong adhesive or screwed to the corner or wall or ceiling, as compared to tiled, although it is different from tiled. The sound effect has been enhanced by attaching.

  Many of these sound rooms are made by sound equipment manufacturers, universities, research laboratories, etc., and if there is room or special demand, listening rooms are usually used in ordinary houses. It has been created as a special room.

  In general housing, curtains are attached to the windows for the living room as a normal living space, and in the housing complex, the boundary wall with the adjacent house is made soundproof, or between the upper and lower houses. Although soundproofing measures such as making the floor soundproof have been taken, there are currently no measures taken to control indirect and reverberant sound in individual living rooms.

JP-A-8-129389 JP-A-6-149265 JP-A-8-246574 JP-A-7-102657

  As explained above, acoustic chambers that have been made in the past should be fitted with acoustic adjustment members using special construction of the room or permanent adhesion in accordance with it so that the installed acoustic adjustment members will not fall. Have gone and realized.

  Therefore, the cost for enhancing the acoustic effect of the room is high, the effective volume of the room is narrowed, and it is often impossible to change it once it is made, and the impression that the acoustic room cannot be made easily is given. Was giving. For example, if the acoustic adjustment member is attached to a part of a corner, wall, or ceiling with an adhesive for construction, and if you want to change the arrangement of the acoustic adjustment member due to room replacement, the original installation If the acoustic adjustment member is peeled from the part, there is a high risk of the wallpaper being torn or the wall being damaged, and changing the acoustic chamber has not been easy.

  In addition, so-called noise countermeasures such as curtains on windows and soundproofing measures for walls and floors have been taken for living rooms as ordinary living spaces in ordinary houses. There has been little emphasis on enhancing the sound effect in order to improve comfort such as comfort.

  A traditional Japanese-style room with wooden walls and earthen walls, but when you actually enter it, it has been felt that it is somewhat calm and comfortable, but the number of craftsmen who create such Japanese-style rooms is decreasing However, the cost was high, and it was felt that it was not very feasible for many people.

  In practice, there has been little research on indirect and reverberant sounds for living rooms as ordinary living spaces in ordinary houses, and control of these indirect and reverberant sounds makes it easier to hear the conversation of people in the room. It has hardly been considered that it contributes greatly to comfort, such as being.

  In recent years, with the development of IC (semiconductor integrated circuits) and the development of liquid crystal display devices and plasma displays, televisions have become smaller and thinner, and acoustic devices have been made smaller and thinner. In the case of a television using a cathode ray tube as a display device, for example, in the case of a room of 6 tatami mats or 10 tatami mats, it is often desirable to place the television in the corner of the room. This is especially true for large televisions. However, in the case of a television using liquid crystal as a display device, it is often desirable to place the television in a position parallel to the wall and close to the wall.

  With the development of household electrical devices and economic development, many people want to purchase flat-screen TVs and audio devices and change the arrangement of furniture. When the room is a room to which an acoustic adjustment member is attached, the acoustic state of the room naturally changes due to the change of the sound source, and the room in the preferred acoustic state often changes to a room in an unfavorable acoustic state. Therefore, if the arrangement of the acoustic adjustment member is changed, there is a large problem in that it requires a high cost for that purpose, and further, scratches remain on the walls and the like, and further construction costs are required to cure it. It was. Also, if the room does not have a sound adjustment member attached, if you want to hear good quality sound, you can install a sound adjustment member at a higher cost or purchase a thin TV or sound device with good sound quality. I had to rely on the means.

  In addition, there are many hopes to live in a Japanese-style room with a calm and cozy earthen wall, but creating such a Japanese-style room is generally expensive and cannot be realized easily. Was the current situation.

  The present invention has been made in view of these points, and the object of the present invention is practically applied to both a listening room and a living room as a normal living space in a general house. Provide a sound adjustment member that is detachable and easy to install, a method for installing the sound adjustment member, and a structure to which the sound adjustment member is attached, so that a calm and comfortable room can be realized easily and inexpensively. It's where you can do it.

  As described above, attaching an acoustic adjustment member to a corner, wall, ceiling, etc. of a room to enhance the acoustic effect of the room was performed in an acoustic room, but as a normal living space in a general house In the living room, it was considered that it was not worth doing because of the above-mentioned circumstances.

  However, as a result of research by the inventors of the present invention, in the living room as a normal living space in a general house, by using an appropriate acoustic adjustment member to the corner, wall and ceiling, which was not conventionally excluded, It was found that the sound quality of normal human conversation can be greatly changed, and the indirect sound characteristics and reverberant sound characteristics in the room can be changed. As a result, it was found that when changing the acoustic equipment such as a television and the arrangement thereof, the cozy living environment can be maintained by changing the type, size, arrangement, etc. of the acoustic adjustment member accordingly.

  However, even if it turns out that it is possible to make a comfortable room by using such an acoustic adjustment member, due to the above-mentioned conventional circumstances, that is, the cost is high, the layout change is performed once the acoustic adjustment member is attached. It is difficult to attach the acoustic adjustment member to the living room as a normal living space in ordinary houses due to the conventional idea that the rearrangement of the acoustic adjustment member will damage the wall or require a lot of construction work It was thought.

Adhesive or pressure-sensitive adhesive that can be detachably attached to a wall or the like multiple times (hereinafter, adhesive or pressure-sensitive adhesive that can be detachably attached to a wall or the like multiple times) It was also proposed to detachably attach to the corners, walls, and ceiling of the room.

  The re-peelable adhesive referred to in the present invention is, for example, not limited to this, but a relatively light acoustic adjustment member such as one having a sound control member such as a maltoplane made of porous synthetic resin is used as a wall. It is an adhesive that can remove an acoustic adjustment member attached without damaging a wall surface such as wallpaper used for a normal indoor interior even if it is slowly peeled off after being mounted on the wall. Adhesives and pressure-sensitive adhesives that are commercially available as re-peelable adhesives, re-peelable adhesives, etc. can also hold the acoustic adjustment member on the attachment part, and slowly remove the acoustic adjustment member from the attachment part.
