SW GROOVED ACOUSTIC PANEL is a commonly used building acoustic sound absorbing material. It is a structure with slots on the front and holes on the back. It forms a resonance sound-absorbing structure with the eco friendly acoustic foam filled at the back and the back cavity formed toward the wall or the ceiling.
It has excellent sound absorption effect for low and medium and high frequencies, and is widely used in auditoriums, conference rooms, multi-function halls, gymnasiums, offices and other places.
