Acoustic transmission — in building design refers to a number of processes by which sound can be transferred from one part of a building to another. Typically these are: #Airborne transmission a noise source in one room sends air pressure waves which induce vibration to … Wikipedia
Acoustic 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… … Wikipedia
Transmission line — This article is about the radio frequency transmission line. For the power transmission line, see electric power transmission. In communications and electronic engineering, a transmission line is a specialized cable designed to carry alternating… … Wikipedia
Acoustic quieting — This article primarily discusses mechanical and acoustic noise. See Noise reduction for electronic noise. : For noise masking by saturation, see Sound masking or pink noise.Acoustic quieting is the process of making machinery quieter by damping… … 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 Model — An acoustic model is created by taking audio recordings of speech, and their text transcriptions, and using software to create statistical representations of the sounds that make up each word. It is used by a speech recognition engine to… … 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 fingerprint — For acoustic emissions of ships and submarines, see Acoustic signature. An acoustic fingerprint is a condensed digital summary, deterministically generated from an audio signal, that can be used to identify an audio sample or quickly locate… … 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 shock — The term acoustic shock is used to describe the symptoms a person may experience after hearing an unexpected, loud sound via a telephone. The loud sound, called an Acoustic Incident, can be caused by feedback oscillation, fax tones, signalling… … Wikipedia
Acoustic network — An acoustic network is a method of positioning equipment using sound waves. It is primarily used in water, and can be as small or as large as required by the users specifications.The simplest acoustic network consists of one measurement resulting … Wikipedia
