• 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 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 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 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 Emission — (AE) is a naturally occurring phenomenon whereby external stimuli such as mechanical loading generate sources of elastic waves. AE occurs when a small surface displacement of a material is produced. This occurs due to stress waves generated when… …   Wikipedia

• 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 resonance — is the tendency of an acoustic system to absorb more energy when the frequency of its oscillations matches the system s natural frequency of vibration (its resonance frequency ) than it does at other frequencies. A resonant object will probably… …   Wikipedia

• Acoustic thermometry — of Ocean Climate (ATOC) is an idea to observe the state of the world s oceans, and the ocean climate in particular, using long range acoustic transmissions. Prototype measurements of temperature have been made in the North Pacific Basin and… …   Wikipedia

• Acoustic levitation — is a method for suspending matter in a medium by using acoustic radiation pressure from intense sound waves in the medium. Acoustic levitation is possible because of the non linear effects of intense sound waves. [Cite web… …   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
