Earcons Gyp Aco Perforated Panel

Earcons 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. Perforated Panel has been designed for use on ceilings and walls where an increased level of sound attenuation is required. Acoustic properties of the board are achieved by perforations of the board surface that absorb sound to reduce echoes and reverberation. The long edges of the panels are recessed for flush jointing to a smooth, continuous surface. Earcons perforated gypsum board is one of the best sound absorption products, it is widely used in Auditorium, Library, Office, Cinema, Church, Hospital. School, Exhibition, Studios and so on.

Product feature

Perforation Variants (Square hole)

Our high density gypsum panels come in a variety of perforations and sizes to meet your architectural goals. They consume large quantities of ambient sound energy creating significantly quieter atmospheres for any space where the listening or learning environment is critical. Earcons Gyp Aco panels come in many perforation designs ranging from Circle , Square & Capsule shape. The perforated board absorbs sound that would otherwise reflect back into the room.

Painting and Decoration

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
