  • 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 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 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 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 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 … and More — Album par Angra Sortie 1998 Enregistrement en 1994 et 1995 Durée 41 min 22 s Genre Heavy metal Power metal …   Wikipédia en Français

  • 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

  • Speed of sound — Sound is a vibration that travels through an elastic medium as a wave. The speed of sound describes how much distance such a wave travels in a certain amount of time. In SI Units with dry air at 20 °C (68 °F), the speed of sound is 343 m/s. This… …   Wikipedia

  • Acoustic metric — In mathematical physics, a metric describes the arrangement of relative distances within a surface or volume, usually measured by signals passing through the region – essentially describing the intrinsic geometry of the region. An acoustic metric …   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 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
