Acoustic Polyester Fiber Board For Wall High Density Sound Absorbing Insulation

Sound absorption properties
Polyester fibre acoustic panels and other porous materials with similar sound absorption characteristics, sound absorption coefficient with the increase in frequency and increase, high frequency sound absorption coefficient is very large, its back to leave the cavity and the space with which it is composed of sound absorption body can greatly improve the sound absorption performance of the material. The coefficient of noise reduction is roughly 0.8 to 1.10, making it an efficient sound absorber for a wide frequency band.
