Acoustic Radiation Force Impulse (ARFI) Imaging — uses acoustic radiation force to generate images of the mechanical properties of soft tissue. How it worksAcoustic radiation force is a phenomenon associated with the propagation of acoustic waves in attenuating media. Attenuation includes both… … 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 cleaning — is used wherever there is a build up of dry materials and particulates which need to be cleaned regularly to ensure maximum efficiency and minimize maintenance and down time. An acoustic cleaner works by generating powerful sound waves which will … 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 location — is the art and science of using sound to determine the distance and direction of something. Location can be done actively or passively, and can take place in gases (such as the atmosphere), liquids (such as water), and in solids (such as in the… … Wikipedia
Acoustic analogy — Acoustic analogies are applied mostly in numerical aeroacoustics to reduce aeroacoustic sound sources to simple emitter types. They are therefore often also referred to as aeroacoustic analogies.In general, aeroacoustic analogies are derived from … Wikipedia
Acoustic rheometer — employes piezo electric crystal that can easily launch a successive wave of extensions and contractions into the fluid. It applies an oscillating extensional stress to the system. System response can be interpreted in terms of extensional… … Wikipedia
Acoustic transmission lines — An acoustic transmission line is the acoustic analog of the electrical transmission line, typically thought of as a rigid walled tube that is long and thin relative to the wavelength of sound present in it. Pipe organs, woodwinds, and the like… … 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
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
acoustic delay line — noun a delay line based on the time of propagation of sound waves • Syn: ↑sonic delay line • Hypernyms: ↑delay line • Part Holonyms: ↑acoustic storage … Useful english dictionary
