Acoustic wave equation

From Wikipedia, the free encyclopedia

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 r 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.
