An acoustic absorber is an acoustic device whose construction aids in the absorption, or damping, of sound. This can significantly improve the acoustic parameters of even small rooms and shorten the reverberation time, which can affect listening experiences and the quality of sound transmission. Acoustic absorbers dampen sounds by reducing the energy of acoustic waves and preventing their reflection. They can also be used at medium and high frequencies.
Sound absorbers have a multilayer structure and are made alternately from materials with high surface mass and materials with light surface mass, such as acoustic wool or cork. These acoustic devices are suitable for installation on walls or ceilings. They are used, among others, in recording studios, concert halls, opera houses, theaters, as well as in exercise rooms and university auditoriums.
Acoustic absorbers can have various structures, shapes, and technical specifications.
