A form of energy that creates a wave that can be detected by our ears.
An oscilation of air pressure. One wave is measured from the point of null (average room) pressure past both points of greatest (crest) and least (trough) pressure to the point of normal pressure. The length of the wave is measured in feet. The frequency is measured in Hertz (when time is factored in).
The pattern of the changes in air pressure through time that results in the percept of a sound. go to glossary index
