Description
Polyester acoustic panels can replace sponge, glass fiber, rock wool, and other harmful traditional sound-absorbing panels, a new type of environmentally sound insulation material. It can be in direct contact with the human body and not hurt the human body, will not release pollutants, can adjust reverberation time according to different needs, clear sound impurity, improve the sound effect and improve speech clarity.
It 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 architectural decoration.
