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 t_{1} and t_{2} is defined as
1/(t_{2}  t_{1}) ∫_{t1}^{t2} x(t) dt 
where x(t) is the amplitude of the sound in Pa.
