Wooden sound-absorbing panels are a relatively common sound-absorbing material. Wooden sound-absorbing panels mainly include grooved wood sound-absorbing panels, perforated wood sound-absorbing panels, and wood wool sound-absorbing panels. Then wooden sound-absorbing panels are mainly made of strips of wood, so It can also be called a wooden sound-absorbing panel,
Acoustic body. In sound-absorbing structures, micro-perforated plates have been widely used. The micro-perforated plate sound absorber can effectively absorb those middle and high frequency sounds that are actually redundant and harmful. Currently the most used is perforated mineral wool board. In addition to micro-perforated plates, foams or sponges can also be used.
The proportion design of sound-absorbing wall should be reasonable. Too much sound-absorbing will cause the sound to be "dry" and affect the singing effect. Therefore, there should be a certain sound reflection in the box. For example, the design of hard floor, the wall is made of log mosaic and part of the sound absorption The wall design can solve the problem of insufficient reverberation ratio
Then it is to ensure that the storage environment is clean, dry, and ventilated, and pay attention to rain. It is to beware of moisture absorption and deformation of the sound-absorbing panel.
