WELLYOUNG Gypsum Acoustics-perforated 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.
WELLYOUNG perforated gypsum board is one of the best sound absorption products, it ie widely used in Auditorium, office, cinema, church, hospital. School and so on.

Applications:
Finishes applied to plasterboard surfaces can have a significant effect on the perceived quality of the installation, particularly where critical lighting conditions exist.
Textured or heavy patterned finishes tend to hide imperfections
Matt finishes minimize imperfection visibility
Semi-gloss and gloss finishes highlight imperfections
Light colours are less likely to show imperfections and impact damage
