12mm thickness 3mm square hole sound damping gypsum board
Wellyoung acoustic perforated gypsum board is designed on the basis of helholtz resonance theorem, After perforated, the holes, board and the wall make up of many resonant cavities, when air molecules pass the holes, the resonant cavities will consume large quantities of sound energy. It is widely used in auditorium, office, cinema, hospital, school and so on.
