Acoustic Research — was a Cambridge, Massachusetts based company that manufactured high end audio equipment. The brand is now owned by Audiovox. Acoustic Research was well known for the AR 3 series of speaker systems, which used the 12 inch (305 mm) acoustic… … Wikipedia
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 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 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 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 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 phonetics — is a subfield of phonetics which deals with acoustic aspects of speech sounds. Acoustic phonetics investigates properties like the mean squared amplitude of a waveform, its duration, its fundamental frequency, or other properties of its frequency … Wikipedia
Acoustic droplet ejection — (ADE) uses a pulse of ultrasound to move low volumes of fluids (typically nanoliters or picoliters) without any physical contact. This technology focuses acoustic energy into a fluid sample in order to eject droplets as small as a picoliter. ADE… … Wikipedia
Acoustic tags — are small sound emitting devices that allow the detection and/or remote tracking of fish in three dimensions. Commonly used to monitor the behavior of fish, studies are conducted in lakes, rivers, tributaries, estuaries and at sea. Acoustic tag… … Wikipedia
Acoustic enhancement — is a subtle type of sound reinforcement system used to augment direct, reflected, or reverberant sound. While sound reinforcement systems are usually used to increase the sound level of the sound source (like a person speaking into a microphone,… … Wikipedia
Acoustic lubrication — Acoustic or sonic lubrication occurs when sound (measurable in a vacuum by placing a microphone on one element of the sliding system) permits vibration to introduce separation between the sliding faces. This could happen between two plates or… … Wikipedia
