Reverberation chamber
A reverberation chamber is a room equipped for acoustic measurements. Its highly sound-reflective walls cause strong reverberation, creating a diffuse noise field with long reverberation times.

Sound insulation
Sound insulation is the acoustic shielding of a room or device in order to prevent or reduce the transmission of air-borne or solid-borne sound to neighboring spaces. The aim is to prevent the sound from propagating by using sound insulation materials to build a sound barrier around the noise source.
Closed-cell foams
In closed-cell foams, the walls between the individual cells are completely closed. As this prevents the penetration of liquids and vapor etc., closed-cell foams are suitable for use also in spaces with increased moisture load.
Noise control
Equipping the room with noise control materials reduces the sound level (and hence the perceived noisiness) and improves speech intelligibility. Such an improvement of acoustic conditions makes for a much more pleasant atmosphere. Porous and fibrous materials such as open-cell foams or non-wovens are excellent sound absorbers. But also closed-cell foams with a special cell structure, for instance our soni RESIST, score with good sound absorption capacity.
