Polyester Fiber Acoustic Panels
Polyester fiber material has various densities and good air permeability, and is an ideal product in sound absorbing and heat insulating materials. The highest sound absorption coefficient is above 0.8 in the noise range of 125~4000HZ. Used as indoor sound absorbing material, it can effectively shorten the reverberation time, absorb excess reverberation sound, improve hearing adjustment, and improve language clarity. Therefore, polyester fiber acoustic panels are widely used in the field of architectural decoration.
