2. Beat (acoustics) - Wikipedia

   en.wikipedia.org/wiki/Beat_(acoustics)

   Time duration of 10 seconds Binaural Beats Base tone 200 Hz, beat frequency from 7 Hz to 12.9 Hz. Time duration of 9 minutes. Time duration of 9 minutes. A binaural beat is an auditory illusion perceived when two different pure-tone sine waves , with a less-than 40 Hz or so difference between them, are presented to a listener dichotically (one ...

3. Acoustic resonance - Wikipedia

   en.wikipedia.org/wiki/Acoustic_resonance

   The term "acoustic resonance" is sometimes used to narrow mechanical resonanceto the frequency range of human hearing, but since acousticsis defined in general terms concerning vibrational waves in matter,[1]acoustic resonance can occur at frequencies outside the range of human hearing.

4. Brainwave entrainment - Wikipedia

   en.wikipedia.org/wiki/Brainwave_entrainment

   Brainwave entrainment is a colloquialism for 'neural entrainment', [25] which is a term used to denote the way in which the aggregate frequency of oscillations produced by the synchronous electrical activity in ensembles of cortical neurons can adjust to synchronize with the periodic vibration of external stimuli, such as a sustained acoustic ...

5. Musical acoustics - Wikipedia

   en.wikipedia.org/wiki/Musical_acoustics

   Musical acoustics or music acoustics is a multidisciplinary field that combines knowledge from physics, [ 1 ][ 2 ][ 3 ] psychophysics, [ 4 ] organology [ 5 ] (classification of the instruments), physiology, [ 6 ] music theory, [ 7 ] ethnomusicology, [ 8 ] signal processing and instrument building, [ 9 ] among other disciplines.

6. Audio frequency - Wikipedia

   en.wikipedia.org/wiki/Audio_frequency

   t. e. An audio frequency or audible frequency ( AF) is a periodic vibration whose frequency is audible to the average human. The SI unit of frequency is the hertz (Hz). It is the property of sound that most determines pitch. [ 1] The generally accepted standard hearing range for humans is 20 to 20,000 Hz. [ 2][ 3][ 4] In air at atmospheric ...

7. Acoustic levitation - Wikipedia

   en.wikipedia.org/wiki/Acoustic_levitation

   Acoustic levitation is a method for suspending matter in air against gravity using acoustic radiation pressure from high intensity sound waves. [1] [2] It works on the same principles as acoustic tweezers by harnessing acoustic radiation forces. However acoustic tweezers are generally small scale devices which operate in a fluid medium and are ...
