Decibel
The decibel (dB) unit specifies the sound pressure level on a logarithmic scale. The sound pressure level determines a sound’s loudness. As it is a logarithmic value, which means that a sound increasing by 10 dB is perceived as approximately twice as loud. Noise with more than 90 dB presents the risk of hearing damage.
Air-borne sound insulation
Air-borne sound insulation impedes the transmission of air-borne sound to adjacent areas. This can be achieved for ex. through the encapsulation of the sound source or the construction of noise insulation walls. Effective insulation requires heavy and preferably flexible acoustic materials.

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.
