Wood sound-absorbing board

Wood sound-absorbing board can be divided into two types: grooved wood sound-absorbing board and perforated wood sound-absorbing board. Grooved wood sound-absorbing board is a kind of slit resonance sound-absorbing material with slots in the front and holes in the back of MDF. The perforated wood sound-absorbing board is a kind of structural sound-absorbing material with round holes on the front and back of the MDF. Two kinds of sound-absorbing boards are often used for wall and ceiling decoration.

Cross-sectional structure of wood sound-absorbing board: the principle of sound-absorbing board: There are many small holes on the surface of sound-absorbing board. After the sound enters the small holes, it will be reflected randomly in the inner wall of the structure which is a bit like a sponge until most of the energy of sound waves is consumed and turned into heat energy, thus achieving the effect of sound insulation. There are many tiny gaps in the sound-absorbing board, which have a sound-absorbing effect on sound waves, especially for sound waves with frequencies higher than 600Hz.Introduction of commonly used sound-absorbing materials.
