The energy transmitted per unit time and area by a SOUND WAVE. The term is used generally to denote the magnitude of a sound. The measurement of intensity is called INTENSITY LEVEL (see DECIBEL).

See Appendix D for the conversion of intensity ratios to decibels, and SOUND INTENSITY for a fuller discussion.
