Acoustic intensity.


Acoustic intensity, also called sound intensity, is the sound energy flux per unit area. Specifically, it is the average rate of sound energy transmitted through a unit area normal to the direction of sound transmission.

 

The usual context is the measurement of sound intensity in the air at a listener's location. The basic units are watts per square meter (W/m2) or watts per square centimeter (W/cm2).
