And a surface layer made of a cosmetic material having sound permeability and breathability on the humidity control layer, or on a humidity control layer made of a humidity control material having sound permeability and breathability. A sound absorbing layer made of a sound absorbing material having breathability, and a surface layer made of a decorative material having sound permeability and breathability on the sound absorbing layer, and further having sound permeability and breathability. The humidity control material has
Non-breathable, acoustically transparent insulation board, sheathing board, particle board, board thickness 3 mm
Since it is provided with ventilation through holes in any of the above plywood, calcium silicate, gypsum board, and asbestos board, it has both a humidity control function and a sound absorption function. Therefore, the humidity in the atmosphere was adjusted to keep the humidity at the installation location almost constant, and when used in an acoustic hall etc. due to the acoustic function, a pure sound with little reverberation was obtained, and it was used as a building material for general houses. In that case, a soundproofing effect is obtained. Further, in particular, since the present invention is configured to provide a humidity control layer that is made of a humidity control material provided with ventilation through holes while transmitting sound, this humidity control layer can increase the specific surface area. At the same time, the circulation of gas can be improved. Therefore, the moisture in the atmosphere at the installation location of the humidity control sound absorbing plate can be sufficiently absorbed by the humidity control layer, and the humidity in the atmosphere can be adjusted and kept substantially constant. Since it can be passed and absorbed by the sound absorbing layer, it is possible to obtain a pure sound with little reverberation. Further, since the humidity control sound absorbing plate of the present invention has one panel having both the humidity control function and the sound absorbing function, the occupied space can be reduced, and both the conventional humidity control plate and the sound absorbing plate are used. The indoor space can be expanded as compared to the case where it is used.
