  • acoustic waves — akustinės bangos statusas T sritis Standartizacija ir metrologija apibrėžtis Tamprios medžiagos dalelių virpamojo judesio sklidimas. Pagal virpesių dažnį f akustinės bangos skirstomos į infragarsą (f mažiau nei 16 Hz), garsą (f nuo 16 Hz iki 20 · …   Penkiakalbis aiškinamasis metrologijos terminų žodynas

  • 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 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 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 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 wave — An acoustic wave is a weak compression wave (meaning a small pressure change) that moves at the speed of sound. As opposed to a shock wave, the pressure change is continuous, and the wave is isentropic, meaning energy is conserved as it… …   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 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 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 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

  • Waves Audio — Ltd. is a developer and supplier of professional audio signal processing technologies and audio effects, used in recording, mixing, mastering, post production, surround, live, and broadcast sound. Since the early 1990s, Waves processors have been …   Wikipedia
