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 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 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 ohm — any one of several units measuring sound resistance. These units got their name by analogy with electric resistance, which is measured in ohms. The sound resistance across a surface in a given medium is defined to be the pressure of the… … Dictionary of units of measurement
Acoustic reflex — The acoustic reflex (stapedius reflex, attenuation reflex, or auditory reflex) is an involuntary muscle contraction that occurs in the middle ear of mammals in response to high intensity sound stimuli.When presented with a high intensity sound… … Wikipedia
acoustic impedance — Acoustics. the total reaction of a medium to the transmission of sound through it, expressed as the ratio of sound pressure to particle velocity at a given point in the medium. * * * ▪ physics absorption of sound in a medium, equal to the… … Universalium
Computational Aeroacoustics — While the discipline of Aeroacoustics is definitely dated back to the first publication of Sir James Lighthill[1][2] in the early 1950s, the origin of Computational Aeroacoustics can only very likely be dated back to the middle of the 1980s.… … Wikipedia
Quartz crystal microbalance — A quartz crystal microbalance (QCM) measures a mass per unit area by measuring the change in frequency of a quartz crystal resonator. The resonance is disturbed by the addition or removal of a small mass due to oxide growth/decay or film… … Wikipedia
Aeroacoustics — is a branch of acoustics that studies noise generation via either turbulent fluid motion or aerodynamic forces interacting with surfaces. Noise generation can also be associated with periodically varying flows. Although no complete scientific… … Wikipedia
