Acoustic transmission

Example of airborne and structure-borne transmission of sound, where Lp is sound pressure level, A is attenuation, P is acoustical pressure, S is the area of the wall [m²], and τ is the transmission coefficient

Acoustic transmission is the transmission of sounds through and between materials, including air, wall, and musical instruments.

The degree to which sound is transferred between two materials depends on how well their acoustical impedances match.
