In addition to their unique machine-gun-like “bill-clattering”, shoebill storks also produce other unusual sounds: Mates may emit low, mooing sounds that sound like a cow. Shoebill families ...
The audible sound of a gun discharging, also known as the muzzle report or gunfire, may have two sources: the muzzle blast itself, which manifests as a loud and brief "pop" or "bang", and any sonic boom produced by a transonic or supersonic projectile, which manifest as a sharp whip-like crack that persists a bit longer.
Ingestion of the muzzle flash from aircraft-mounted guns has also been implicated in compressor stall and flameout, causing loss of aircraft. [4] Flash hiders attempt to suppress the flash mechanically, by interfering with the blast wave using either a cone or a series of slots at the muzzle of the firearm.
A long-range acoustic device (LRAD), acoustic hailing device (AHD) or sound cannon is a specialized loudspeaker that produces sound at high power for communicating at a distance. It has been used as a method of crowd control , which has caused permanent hearing damage , having an extremely high decibel capacity (up to 160 dB measured at one ...
Typical cyclic rates of fire are 600–1100 rpm for assault rifles, 400–1400 rpm for submachine guns and machine pistols, and 600–1,500 rpm for machine guns. M134 Miniguns mounted on attack helicopters and other combat vehicles can achieve rates of fire of over 100 rounds per second (6,000 rpm).
Certain words in the English language represent animal sounds: the noises and vocalizations of particular animals, especially noises used by animals for communication. The words can be used as verbs or interjections in addition to nouns , and many of them are also specifically onomatopoeic .
The sound ranging operators used equipment that augmented human hearing. Using the gun flash, the flash crew would determine a bearing to the gun using a theodolite or transit. The sound detection crew would determine the difference in time between the gun flash and the sound of the gun, which was used to determine the range of the gun.
High-amplitude sound of a specific pattern at a frequency close to the sensitivity peak of human hearing (2–3 kHz) is used as a burglar deterrent. [ 6 ] Some police forces have used sound cannons against protesters, for example during the 2009 G20 Pittsburgh summit , [ 7 ] the 2014 Ferguson unrest , [ 8 ] and the 2016 Dakota Access Pipeline ...
