Study and characterisation of the acoustic properties of materials. Sound absorption is the quality possessed by all materials to transform part of the sound energy that impacts against them into heat; in other words these materials have the capacity to absorb a large part of the acoustic energy that impacts against them and, therefore, are used to reduce the acoustic level in the space where noise occurs.
