  2. Friction Acoustics - Wikipedia

    en.wikipedia.org/wiki/Friction_Acoustics

    Vibrational energy induced by either kinetic or breakaway friction can cause modal excitation of a subset of the contacting bodies or the vibratory coupling of the multiple bodies, depending on the strength of coupling. Friction noise can be the product of multiple distinct dynamic processes, sliding and stick-slip. Sliding generally leads to ...

  3. Stokes's law of sound attenuation - Wikipedia

    en.wikipedia.org/wiki/Stokes's_law_of_sound...

    In acoustics, Stokes's law of sound attenuation is a formula for the attenuation of sound in a Newtonian fluid, such as water or air, due to the fluid's viscosity.It states that the amplitude of a plane wave decreases exponentially with distance traveled, at a rate α given by = where η is the dynamic viscosity coefficient of the fluid, ω is the sound's angular frequency, ρ is the fluid ...

  4. Friction idiophone - Wikipedia

    en.wikipedia.org/wiki/Friction_idiophone

    Terpodion; sound produced by friction of wood or metal arms against a rotating cylinder Chladni plate example; sound produced by friction of the bow against a plate such as a metal rectangle. Friction idiophones is designation 13 in the Hornbostel-Sachs system of musical instrument classification.

  5. Sound - Wikipedia

    en.wikipedia.org/wiki/Sound

    In physics, sound is a vibration that propagates as an acoustic wave through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain. [1]

  6. Voiceless bilabial plosive - Wikipedia

    en.wikipedia.org/wiki/Voiceless_bilabial_plosive

    Nonetheless, the /p/ sound is very common cross-linguistically. Most languages have at least a plain /p/ , and some distinguish more than one variety. Many Indo-Aryan languages , such as Hindustani , have a two-way contrast between the aspirated /pʰ/ and the plain /p/ (also transcribed as [p˭] in extensions to the IPA ).

  7. Tube sound - Wikipedia

    en.wikipedia.org/wiki/Tube_sound

    Tube sound (or valve sound) is the characteristic sound associated with a vacuum tube amplifier (valve amplifier in British English), a vacuum tube-based audio amplifier. [1] At first, the concept of tube sound did not exist, because practically all electronic amplification of audio signals was done with vacuum tubes and other comparable ...

  8. Sound localization - Wikipedia

    en.wikipedia.org/wiki/Sound_localization

    Sound localization is a listener's ability to identify the location or origin of a detected sound in direction and distance. The sound localization mechanisms of the mammalian auditory system have been extensively studied. The auditory system uses several cues for sound source localization, including time difference and level difference (or ...

  9. Violin acoustics - Wikipedia

    en.wikipedia.org/wiki/Violin_acoustics

    Violin acoustics is an area of study within musical acoustics concerned with how the sound of a violin is created as the result of interactions between its many parts.These acoustic qualities are similar to those of other members of the violin family, such as the viola.
