acoustic wavelength
1Acoustic 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… …

3Acoustic transmission lines — An acoustic transmission line is the acoustic analog of the electrical transmission line, typically thought of as a rigid walled tube that is long and thin relative to the wavelength of sound present in it. Pipe organs, woodwinds, and the like… …
4Acoustic 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 …

6Acoustic contrast factor — The acoustic contrast factor is a number used to describe the relationship between the densities and the sound velocities (or, equivalently because of the form of the expression, the densities and compressibilities) of two media. It is most often …
7Acoustic interferometer — An acoustic interferometer is an instrument for measuring the physical characteristics of sound waves in a gas or liquid. It may be used to measure velocity, wavelength, absorption, or impedance. A vibrating crystal creates the ultrasonic waves… …
8Radio acoustic sounding system — A radio acoustic sounding system (RASS) is a system for measuring the atmospheric lapse rate using backscattering of radio waves from an acoustic wave front to measure the speed of sound at various heights above the ground. This is possible… …
9Ion acoustic wave — An ion acoustic wave is a longitudinal oscillation of the ions (and the electrons) much like acoustic waves traveling in neutral gas. However, because the waves propagate through positively charged ions, ion acoustic waves can interact with their …
10Acousto-optics — is a branch of physics that studies the interactions between sound waves and light waves, especially the diffraction of laser light by ultrasound or sound in general.IntroductionOptics has had a very long and full history, from ancient Greece,… …
