In the first and second embodiments described above, the sound environment adjustment devices 100a and 100c are illustrated in which the panel 50 is movably provided while being maintained parallel to the wall surface W of the meeting room at a certain distance. In this embodiment, a sound environment adjustment device 100c is illustrated in which a panel 50 is movably provided so as to move away from and approach a wall surface W in a meeting room.

As shown in FIG. 10, the sound environment adjustment device 100c includes a panel 50 and a pair of stands 53 that are attached to the lower part of the panel 50 and have casters on the bottom , so that the panel 50 is placed on the floor F. It is provided so as to be movable with respect to the wall surface W in the meeting room in a self-supporting state. Here , the panel 50 is independently movably provided on the floor F so as to be disposed diagonally with respect to the two adjacent walls W in a corner where two adjacent walls W intersect in the meeting room. ing.

The sound environment adjustment device 100c configured as described above adjusts the room acoustics by scattering and reflecting or absorbing the sound waves generated in the meeting room using the panel 50 diagonally arranged on the wall surface W of the meeting room. It is supposed to be done.

As explained above, according to the sound environment adjustment device 100c of the present embodiment, each panel 50 as a whole is made of a highly rigid wood material having a thickness and thickness to suppress warping and deformation. Since each panel 50 is provided with a hollow outer four-periphery frame 30a or 30b made of aluminum or aluminum alloy, each panel 50 can be made lightweight and difficult to deform. Furthermore, a stand 53 with casters is provided at the bottom of each panel 50, so that each panel 50 is provided to be independent and movable on the floor surface F. Therefore, by moving the panel 50 away from the wall W in the meeting room in an independent state, maintenance such as wiping can be easily performed on the wall W. Therefore , it is possible to provide a sound environment adjustment device 100c that is lightweight and difficult to deform, and has excellent maintainability.

Further, according to the sound environment adjustment device 100c of the present embodiment, a plurality of independent panels 50 can be arranged at the four corners of a rectangular meeting room surrounded by four walls in plan view. The sound-absorbing effect of the panel 50, which includes the parallel crosspiece layers, makes it possible to lower the sound pressure level in the meeting room in a low frequency band (approximately 50 Hz to 200 Hz).

《Other embodiments》
In each of the above embodiments, a sound environment adjusting device having a panel having two parallel rail layers has been exemplified, but the present invention provides a sound environment adjusting device having a panel including a plurality of parallel rail layers of three or more layers. It can also be applied to adjustment devices and the like. Note that the configurations disclosed in each of the above embodiments can be applied in combination with the configurations disclosed in other embodiments unless a contradiction occurs.

As described above, the present invention is extremely useful because it can provide a sound environment adjustment device that is easy to maintain by reducing the weight of the panel and making it difficult to deform.
