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.
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.
