4000 GSM ECO-Friendly Polyester Acoustic Felt Panels

Polyester acoustic felt panels are a good choice. Its environmental protection performance is E1 grade, and its fire protection grade is B1 grade. Polyester acoustic felt panels has good sound absorption effect for medium and high frequency. However, due to the limitation of the material structure, the absorption of low-frequency sound is poor, such as the noise generated by electrical appliances, such as the mopping sound generated by slippers upstairs, such as the vibration of the neighbor's sound and the wall caused by vibration. The vibration sound generated by the ground is difficult to eliminate.

Gradient sound-absorbing panels are also a type of polyester acoustic felt panels. It has the environmental protection and flame resistance of ordinary polyester acoustic felt panels, but it is different from ordinary polyester acoustic felt panels. Its density is gradually increasing, not uniform. The hand of gradient sound-absorbing panels feels softer on one side and harder on the other. Generally, the soft surface faces the sound source during installation. Its structure can ensure that it can absorb low frequency, intermediate frequency and high frequency sound at the same time, and the sound absorption efficiency is high.
