Sound waves
Sound waves are mechanical vibrations propagating in liquids, gases and solid bodies and transporting the sound energy emitted by the sound source.
Air-borne sound attenuation
Air-borne sound attenuation is the weakening of an air-borne sound event by means of sound-absorbing materials. Most effective for this purpose are absorber materials that present a large surface area with open pores through which the sound waves can enter. The resulting oscillation of the air molecules inside the pores converts the sound energy into heat due to friction losses at the pore walls.

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.
