Salient Features :

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 resonnt cavities will consume large quantities of sound energy.
Perforated gypsum board is one of the best sound absorption products, it ie widely used in office cinema, church, hospital, school and so on.

Applications :

Absound Perforated gypsum boards are suitable for almost every application including use in auditorium, theatres, convention centres, conference rooms, hospitals, schools, studios, offices and commercial buildings or any area where acoustics and aesthetics are a consideration.
