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… … Wikipedia
Surface acoustic wave — A surface acoustic wave (SAW) is an acoustic wave traveling along the surface of a material having some elasticity, with an amplitude that typically decays exponentially with the depth of the substrate. This kind of wave is commonly used in… … Wikipedia
Acoustic theory — is the field relating to mathematical description of sound waves. It is derived from fluid dynamics. See acoustics for the engineering approach.The propagation of sound waves in a fluid (such as air) can be modeled by an equation of motion… … Wikipedia
Acoustic streaming — is a steady current forced by the absorption of high amplitude acoustic oscillations.This phenomenon can be observed near sound emitters, or in the standing waves within a Kundt s tube.It is the less known opposite of sound generation by a… … Wikipedia
Acoustic impedance — The acoustic impedance Z (or sound impedance) is a frequency f dependent parameter and is very useful, for example, for describing the behaviour of musical wind instruments. Mathematically, it is the sound pressure p divided by the particle… … Wikipedia

Wave equation — Not to be confused with Wave function. The wave equation is an important second order linear partial differential equation for the description of waves – as they occur in physics – such as sound waves, light waves and water waves. It arises in… … Wikipedia
acoustic resistance — The product of wave velocity and rock density indicating the reflective power of a boundary between two strata [16] … Lexicon of Cave and Karst Terminology
Wave field synthesis — (WFS) is a spatial audio rendering technique, characterized by creation of virtual acoustic environments. It produces artificial wave fronts synthesized by a large number of individually driven speakers. Such wave fronts seem to originate from a… … Wikipedia
Acoustic holography — is a method used to estimate the sound field near a source by measuring acoustic parameters away from the source via an array of pressure and/or particle velocity transducers. Measuring techniques included within acoustic holography are becoming… … Wikipedia
acoustic velocity — acoustic velocity, the rate at which a sound wave travels through a specified medium … Useful english dictionary
