Dealing with the problem of noise pollution is becoming increasingly important in spaces where noise volume is naturally high (cinemas, night clubs, restaurants, etc.), and also in private interiors (living rooms, dining rooms, home theater room, etc.) where speech intelligibility is important. When the human body encounters excessive noise the usual results are fatigue and stress. Barrisol® offers the ability to improve acoustic comfort thanks to a line of micro-perforated sheets called Barrisol® Acoustics. Barrisol® Acoustics offers four unique, acoustic stretch ceiling systems : Miniperf, Microacoustic, Acoperf and Microperf.The physics of the sound absorption and the sheeting itself make Barrisol® Acoustics sheets an ideal sound absorption device. Micro-perforations transform the acoustic energy in thermal energy. The viscous friction created when the sound wave meets the air in the micro-perforations is accentuated by the resistance of the air volume enclosed between the material and the ceiling cavity. The technology built into Barrisol® Acoustics sheeting allows it to obtain spectacular acoustic results.The acoustic absorption coefficient of Barrisol® Acoustics depends on four factors: the diameter of the distance between the holes the pattern of micro-perforation the thickness of the sheet the airspace behind the sheet and the ceiling above.These four factors allow a designer to choose the best Barrisol® Acoustics perforation style for their particular application.
