Sound waves may be viewed using parabolic mirrors and objects that produce sound. [ 9 ] The energy carried by an oscillating sound wave converts back and forth between the potential energy of the extra compression (in case of longitudinal waves) or lateral displacement strain (in case of transverse waves) of the matter, and the kinetic energy ...
The cracking sound a bullwhip makes when properly wielded is, in fact, a small sonic boom. The end of the whip, known as the "cracker", moves faster than the speed of sound, thus creating a sonic boom. [2] A bullwhip tapers down from the handle section to the cracker. The cracker has much less mass than the handle section.
A musical instrument is a device created or adapted to make musical sounds. In principle, any object that produces sound can be considered a musical instrument—it is through purpose that the object becomes a musical instrument. A person who plays a musical instrument is known as an instrumentalist. The history of musical instruments dates to ...
If the wave is a sound wave and the sound source is moving faster than the speed of sound, the resulting shock wave creates a sonic boom. Lord Rayleigh predicted the following effect in his classic book on sound: if the observer were moving from the (stationary) source at twice the speed of sound, a musical piece previously emitted by that ...

This is a list of onomatopoeias, i.e. words that imitate, resemble, or suggest the source of the sound that they describe. For more information, see the linked articles. Human vocal sounds Achoo, Atishoo, the sound of a sneeze Ahem, a sound made to clear the throat or to draw attention ...
The sound object is therefore an acoustic action and intention of listening. [1] Schaeffer believed that the sound object should be free from its sonic origin (its sound source, or source bonding) so that a listener could not identify it, what he termed as acousmatic listening. Schaeffer's four functions of the "What Can be Heard" include:
In modern parlance, if a string sounds the note C when plucked, a string twice as long will sound a C an octave lower. In one system of musical tuning , the tones in between are then given by 16:9 for D, 8:5 for E, 3:2 for F, 4:3 for G, 6:5 for A, and 16:15 for B, in ascending order.
A whistle is a device that makes sound from air blown from one end forced through a small opening at the opposite end. They are shaped in a way that allows air to oscillate inside of a chamber in an unstable way. The physical theory of the sound-making process is an example of the application of fluid dynamics or hydrodynamics and aerodynamics ...
