• 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 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 approximation — A fundamental principle in the field of acoustics, the acoustic approximation states that an acoustic wave is created by a small pressure ripple riding on a comparatively large equilibrium (bias) pressure. Typically, the acoustic pressure is on… …   Wikipedia

• Acoustic microscopy — Introduction = Acoustic microscopes employ very high or ultra high frequency ultrasound. These microscopes operate nondestructively and penetrate most solid materials to make visible images of internal features, including defects such as cracks,… …   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 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 radiation pressure — is the difference between the average pressure at a surface moving with the sound displacements (the Lagrangian pressure) and the pressure that would have existed in the fluid of same mean density at rest. See also * Radiation pressure * Acoustic …   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
