Absorption coefficient
Absorption coefficient α is a measure of the effectivity of absorber materials. It indicates the proportion of sound waves that are absorbed. For example, α = 0.5 means that half of the sound energy is absorbed. α = 0 means that the sound waves are not absorbed at all, but completely reflected. α = 1 means that the sound is absorbed in its entirety.
Solid-borne sound
Solid-borne sound (also “structure-borne” sound) is defined as sound waves propagating within or on the surface of a solid medium. When these vibrations excite the surrounding air into oscillating, audible air-borne sound is the result.

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.
