High Density Sound Absorbing Polyester Fibreboard PET Sound Insulation Board Polyester Fibre Felt Sound Insulation Board
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.
