echolocation vs. sonic boom: human use
Posted in the Science Forum
#1 Nov 29, 2012
Echolocation, also called biosonar, is the biological sonar used by several kinds of animals. Echolocating animals emit calls out to the environment and listen to the echoes of those calls that return from various objects near them (source: Wikipedia).
A sonic boom is the sound associated with the shock waves created by an object traveling through the air faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding much like an explosion. The crack of a supersonic bullet passing overhead is an example of a sonic boom in miniature (source: Wikipedia).
Echolocation involves echo-like sounds traveling in wave-like form, while a sonic boom is more like a rapid single line emission or explosion.
Submarines employ emission sonar acoustic technologies that employ brute features of both echolocation and sonic booms.
These process qualities of sound are studied by physicists who seek to understand acoustic impact.
Do these physical considerations reflect the human symbolic value of communication sound-studying (i.e., exclamatory impact rich) Hollywood (USA) movies such as "Oh, God! You Devil" (1984) and "Gotcha!" (1985)?
Are they printing movie posters on hemp/recycled paper yet?
