	<onlyinclude>'''Sound''' is a [[wave]], and like all waves, sound carries [[energy]].

Likewise, when the surfaces of two objects scrape together, [[friction]] makes the molecules vibrate, which creates the pressure waves that produce sound. That means that sounds coming from machinery can tell you that it's losing [[mechanical energy]], like with grinding [[gear]]s.		<onlyinclude>'''Sound''' is a [[wave]], and like all waves, sound carries [[energy]].

	These pressure waves bouncing off of walls and other objects make the sounds less distinct and ordered (the human ear can no longer figure out what's being said after the sound bounces around). Eventually, sound turns into [[thermal energy]], warming the system (usually air). There are exceptions, but usually this small amount of warming is generally hard to detect without special equipment.
