A command available in the Query menu if you select a Sound object. The Info window will show the mean amplitude (sound pressure in Pascal) within a specified time range.
The mean amplitude between the times t1 and t2 is defined as
|1/(t2 - t1) ∫t1t2 x(t) dt|
where x(t) is the amplitude of the sound in Pa.
