Acoustic wave equation

In physics, the acoustic wave equation governs the propagation of acoustic waves through a material medium. The form of the equation is a second order partial differential equation. The equation describes the evolution of acoustic pressure $p$ or particle velocity u as a function of position x and time $t$ . A simplified form of the equation describes acoustic waves in only one spatial dimension, while a more general form describes waves in three dimensions.
