Acoustic theory is the field relating to mathematical description of sound waves.

** Acoustic dispersion, for sound waves

Sometimes, for the sake of appearance or of the desired " feel " of the instrument, a drum with a trigger will be used as a trigger pad by muffling it so heavily that no significant sound at all is produced, see Electronic drum # Acoustic triggered drum kit.

* Acoustic location, the general use of sound to locate objects

Acoustic problems always require allowing compressibility, since sound waves are compression waves involving changes in pressure and density of the medium through which they propagate.

Acoustic stethoscopes are familiar to most people, and operate on the transmission of sound from the chest piece, via air-filled hollow tubes, to the listener's ears.

Acoustic or sound waves travel at speed given by

Acoustic resonance is a branch of mechanical resonance that is concerned with the mechanical vibrations across the frequency range of human hearing, in other words sound.

Acoustic phonetics deals with the physical properties of sound, what sounds exactly are coming from the person speaking.

* Acoustic keyloggers: Acoustic cryptanalysis can be used to monitor the sound created by someone typing on a computer.

; Acoustic tablets: Early models were described as spark tablets — a small sound generator was mounted in the stylus, and the acoustic signal picked up by two microphones placed near the writing surface.

Acoustic energy is variation in the air pressure that can be represented as sound waves, which are then perceived by the human auditory system as sound.

* Scanning Acoustic Tomography, a research process using focused sound

However, Electric Acoustic Stimulation ( EAS ) devices, including the Hybrid " short-electrode " cochlear implant, have been developed that combine a cochlear implant with a sound amplifying hearing aid.

Acoustic amplifiers are designed to produce a " clean ", transparent, " acoustic " sound when used with acoustic instruments with built-in transducer pickups and / or microphones.

* Acoustic amplifiers, similar in many ways to keyboard amplifiers but designed specifically to produce a " clean ," transparent, " acoustic " sound when used with acoustic instruments with built-in transducer pickups and / or microphones.

Acoustic amplifiers are designed to produce a " clean ", transparent, " acoustic " sound when used with acoustic instruments with built-in transducer pickups and / or microphones.

Green Carnation's trend of music has continuously become less and less heavy after every release ; from straight forward death metal, to a gothic metal / doom metal / progressive metal sound, to a melancholic hard rock-sounding form of progressive rock and in 2006, went as far as to releasing an entirely acoustic album Acoustic Verses.

* Acoustic or pressure ( p ) modes, driven by internal pressure fluctuations within a star ; their dynamics being determined by the local speed of sound.

Other efforts included the album Acoustic, spotlighting their " wooden " sound, a duet with Karla Bonoff, " You Believed in Me " for the MCA Olympic compilation, One Voice, and a cover version of Buddy Holly's " Maybe Baby " for the Decca tribute album, Not Fade Away.

Acoustic cavity resonators, in which sound is produced by air vibrating in a cavity with one opening, are known as Helmholtz resonators.

* Acoustic spectroscopy involves radiated pressure waves.

The muffler is engineered as an acoustic soundproofing device designed to reduce the loudness of the sound pressure created by the engine by way of Acoustic quieting.

Acoustic horns convert large pressure variations with a small displacement area into a low pressure variation with a large displacement area and vice versa.

Acoustic analog recording is achieved by a small microphone diaphragm that can detect changes in atmospheric pressure ( acoustic sound waves ) and record them as a graphic representation of the sound waves on a medium such as a phonograph ( in which a stylus senses grooves on a record ).

Acoustic couplers are still used by people travelling in areas of the world where electrical connection to the telephone network is illegal or impractical.

Acoustic resonance is an important consideration for instrument builders, as most acoustic instruments use resonators, such as the strings and body of a violin, the length of tube in a flute, and the shape of, and tension on, a drum membrane.

Adaptive Transform Acoustic Coding ( ATRAC ) is a family of proprietary audio compression algorithms developed by Sony.

Acoustic phonetics is a subfield of phonetics which deals with acoustic aspects of speech sounds.

However, Adaptive Transform Acoustic Coding 3, or ATRAC3, is a separate format developed by Sony )

He also released Acoustic Cafe, an album, that with the exception of " You Have My Heart ," is a collection of covers ranging from Bob Dylan (" If Not For You ," " Make You Feel My Love ") to Cyndi Lauper (" Time After Time ").
