Solid-borne sound attenuation/damping
Solid-borne sound attenuation is the absorption of solid-borne noise by a layer of suitable material, e.g. heavy foil, on the parts/elements where the solid-borne sound propagates. Solid-borne sound attenuation prevents the conversion of solid-borne sound into air-borne sound. For this purpose, the medium’s surface is covered with a homogeneous layer of acoustic material (adhesive fixation or other) that transforms sound energy into other energy forms.
