Human whistle sound. The number and variety of whistles created by humans is quite large, yet very little study has been done on human whistling from a physics perspective. There are three possible mechanisms: Helmholtz resonance, symmetric hole tone operation (monopole), or asymmetric edge tone operation (dipole).
These phenomena can potentially generate vibrations of the ferromagnetic, conductive parts, coils and permanent magnets of electrical, magnetic and electromechanical device, resulting in an audible sound if the frequency of vibrations lies between 20 Hz and 20 kHz, and if the sound level is high enough to be heard (e.g. large surface of ...
A calliope (see below for pronunciation) is a North American musical instrument that produces sound by sending a gas, originally steam or, more recently, compressed air, through large whistles—originally locomotive whistles. A calliope is typically very loud. Even some small calliopes are audible for miles. There is no way to vary tone or volume.
Whistling can be used to control trained animals such as dogs. A shepherd's whistle is often used instead. Whistling has long been used as a specialized communication between laborers. For example, whistling in theatre, particularly on-stage, is used by flymen (members of a fly crew) to cue the lowering or raising of a batten pipe or flat. This ...
A boatswain's call, pipe, or bosun's whistle is a pipe or a non-diaphragm type whistle used on naval ships by a boatswain. The pipe consists of a narrow tube (the gun) which directs air over a metal sphere (the buoy) with a hole in the top. The player opens and closes the hand over the hole to change the pitch.
"Duquesne Whistle" (/ dj uː ˈ k eɪ n / dew-KAYN) is a song written by Bob Dylan and Grateful Dead lyricist Robert Hunter that appears as the opening track on Dylan's 2012 studio album Tempest.

Singing sand dunes, an example of the phenomenon of singing sand, produce a sound described as roaring, booming, squeaking, or the "Song of Dunes". This is a natural sound phenomenon of up to 105 decibels, lasting as long as several minutes, that occurs in about 35 desert locations around the world. The sound is similar to a loud low-pitch rumble.
Johnson would sometimes sing the same song over and over again in the recording studio fifty or more times a day. [6] By 1895, Johnson's two tunes "The Whistling Coon" and "The Laughing Song" were the best-selling recordings in the United States. "The Laughing Song" was number one for ten weeks from April to June 1891, while "The Whistling Coon ...
