Sound energy is the form of energy associated with the vibration or disturbance of matter. Sound waves require some kinds of materials to travel trough.

Sound energo is defined as

W=W_{\mathrm {pot} }+W_{\mathrm {kin} }=\int _{V}{\frac {p^{2}}{2\rho _{0}c^{2}}}dV+\int _{V}{\frac {\rho v^{2}}{2}}dV

With

$p$ - sound pressure
$v$ - Particle velocity
$\rho _{0}$ - density
$c$ - sound speed
