The xylophone (from Ancient Greek ξύλον (xúlon) 'wood' and φωνή (phōnḗ) 'sound, voice'; [1] [2] lit. ' sound of wood ' ) is a musical instrument in the percussion family that consists of wooden bars struck by mallets .
The exhaust pipes in automobile exhaust systems are designed as acoustic resonators that work with the muffler to reduce noise, by making sound waves "cancel each other out". [7] The "exhaust note" is an important feature for some vehicle owners, so both the original manufacturers and the after-market suppliers use the resonator to enhance the ...
It has been proposed that music synthesizers that perform computation, and/or that work by recording and playback of sound samples, or the like, be referred to as quintephones. This class of instrument includes electrophones as a special case. [1]
The criteria for classifying musical instruments vary depending on the point of view, time, and place. The many various approaches examine aspects such as the physical properties of the instrument (shape, construction, material composition, physical state, etc.), the manner in which the instrument is played (plucked, bowed, etc.), the means by which the instrument produces sound, the quality ...
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.
The concept of Helmholtz resonance is fundamental in various fields, including acoustics, engineering, and physics. The resonator itself, termed a Helmholtz resonator, consists of two key components: a cavity and a neck. The size and shape of these components are crucial in determining the resonant frequency, which is the frequency at which the ...
A standing wave. The red dots are the wave nodes. A node is a point along a standing wave where the wave has minimum amplitude.For instance, in a vibrating guitar string, the ends of the string are nodes.
On some instruments (e.g., piano, harp, xylophone), discrete tones are clearly audible when sliding. For example, on a keyboard , a player's fingernails can be made to slide across the white keys or over the black keys, producing either a C major scale or an F ♯ major pentatonic scale , or their relative modes ; by performing both at once, it ...
