What is perforated gypsum board? Where is it mainly used?

Perforated gypsum board is a special board made from ordinary gypsum board with uniform circular holes on the surface. These hole designs make perforated gypsum board have good sound absorption and sound insulation performance, so it is widely used in places where the acoustic environment needs to be controlled, such as concert halls, theaters, recording studios, conference rooms, multi-purpose halls, and offices and residential spaces where noise interference needs to be reduced.

The size and distribution of holes in perforated gypsum board have a direct impact on its sound absorption and sound insulation performance. The larger the holes and the more they are, the better the sound absorption effect of the board, because more sound waves can enter the holes and reflect inside the board, consuming energy. But at the same time, too large holes may also cause the strength and stability of the board to decrease. Therefore, when designing perforated gypsum board, it is necessary to reasonably determine the size and distribution of holes according to the specific use environment and acoustic requirements.
