Sound conditioning of rooms/Reverberation/Sound absorber
Places like restaurants, clubhouses and offices, but also rooms or staircases in private home often present quite high noise levels, making them less comfortable places to stay in. Reverberation (i.e. lingering noise) is the result of sound waves being reflected from hard surfaces (e.g. walls, ceilings or floors). The noise level in a given room can be substantially lowered by reducing the reverberation resp. the reverberation time. For this purpose, part of the room’s interior surfaces can be covered with sound-absorbing materials (e.g. acoustic foams) that absorb the sound waves instead of reflecting them.
Noise
Noise is an undesired sound event perceived as a disturbance or nuisance. Noise can be detrimental to health. Noise in this sense cannot be objectively measured, but depends on the subjective perception of the person exposed to the sound event.

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.
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.
