The Stretch Ceiling can act as a special resonance absorber, also called a micro-perforated sound absorber.
The M-PERF acoustic facility is available with 250,000 +/- perforations per square metre. This enables the user to apply an acoustic treatment to any area without compromising the cosmetic look of the project.
From a physical point of view, this type of absorber acts in a way which is both fascinating and effective, the micro-perforations convert sound energy into heat energy. The viscous friction of air in the holes is reinforced by resonance in the volume of air trapped between the material and the rear wall or existing ceiling, which generates the impressive acoustic properties of the micro-perforated sound absorbers.
The four quantities, diameter of the holes of the micro-perforation, the distance between the holes, the thickness of the panel and thickness of air space between the panel and backing determine the sound absorption coefficient of a micro-perforated sound absorber.
These four quantities allow you to tune a micro-perforated sound absorber to meet various room acoustic demands for speech, music or general noise control for a more pleasant and comfortable environment. The micro-perforation can be applied to a vast array of colours and finishes.
Ideal for restaurants, bars and auditoriums.
The M-PERF acoustic material can offer Class A sound absorption.
