Fireproof performance: Class A

Structure: One piece aluminum alloy frame, filled with custom broadband sound-absorbing foam, foam surface is composited with environmental sound absorption felt, the surface wrapped in a fire-retardant non-combustible sound-absorbing cloth.

Compared with the sound-absorbing material on the indoor surface, the multi-function sound absorber has a high sound absorption efficiency under the same projected area. Multi-function sound absorber is a kind of sound absorption material with high performance absorption hanging in the ceiling, which is featured by less material, light weight, investment saving, high sound absorption efficiency, flexible layout and convenient construction. When the installation area reaches a certain percentage of the total area of the ceiling (generally more than 30%), it can effectively reduce the indoor reverberation time T60, improve language clarity D50 and music clarity C80, effectively improve the environment of the equivalent step-up level (Leq).

Gymnasium, multi-functional hall and other large space venues for control reverberation time.
