Perforated Gypsum Board
This kind of products are used gypsum board as the based board,and deal with drilling on the surface. NRC: UP to 0.96
The perforated gypsum board with a porous structure has many small gaps or continuous bubbles, so it has a certain ventilation. The board, itself has a good ability of medium-high frequency absorption, and the air layer when having on backside can absorb low frequencies.
Raw materials: gypsum board, perforating process and acoustic non-wovens.

Sound absorption level
Sound absorption level depends on the ratio of holes on the acoustic plasterboard and distance between the existing ceiling and the suspended ceiling.
Mineral wool ( glass wool, rock wool ) is recommended to be used for increasing noise absorption performance of suspended ceilings built by using acoustic plasterboard.
Places to use:
•Civil construction need to control the sound loud noise, a place for acoustic treatment :
–Restaurants
–School
–Meeting Room
–Office
–Library
–Acoustic Screens
•Need for specialized acoustic treatment places :
–Such as concert halls, audition room, etc.
–Home decoration, such as wall
–Public places: subway, airport, railway station halls, shopping malls, etc.
Applications
Acoustic plasterboards may be used for reducting resonance in partiting walls and drywall linings in addition to suspended ceilings.
Meanwhile, sound insulation level of partition walls built by acoustic plasterboard declines.
