Sonic speed
Sonic speed (or: speed of sound) cs is the distance travelled per unit of time by a sound wave as it propagates through an elastic medium. The propagation speed depends heavily on the type, temperature and density of the medium. In dry air at 20°C (68°F) and 1 bar air pressure, the speed of sound is 343.2 m/s (1,126 ft/s).

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.
