60 STRETCH CEILINGS BARRISOL ® MICROACOUSTIC ® is a special resonance absorber also called a microperforated sound absorber. From a physical point of view, this type of absorber acts in a way which is both fascinating and effective: the microperforations 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, which generates the impressive acoustic properties of this microperforated sound absorber. Many factors affect room acoustics. Apart from the shape of the room, it is essentially the characteristics of furnishings BARRISOL ACOUSTIC BARRISOL-MICROACOUSTIC ACOUSTIC ® � Initial sound � Sound transformation in thermic energy � <strong>Barrisol</strong> Acoustics � Reduced sound GENERAL DOCUMENTATION Chapter 11 Page 1 such as the materials used for the floor, walls and ceiling which determine how sound is propagated in the room. The dimensions and positions of sound-absorbing areas and also those which reflect sound are essential factors which determine whether room acoustics are "good" or "bad". "Good" acoustics means that the acoustic conditions are appropriate for the use to which the room is put. It is clear that a concert hall needs a different set of acoustics from those of a church or a large office. Theoretically, every room can be structured to provide optimal acoustics for its use. The shape and dimensions of the room are as important when designing acoustics, as is the choice and positioning of materials for the interior and other types of equipment. In practice, however, there is often only a single solution to regulate room acoustics, which is to change the material used for the ceiling and walls. Sound absorbing materials such as BARRISOL ® MICROACOUSTIC ® or other BARRISOL acoustic products are used for targeted adjustment of sound absorption and the room reverberation time.
