Sound exposure level : ウィキペディア英語版
Sound exposure

Sound exposure is the integral, over time, of squared sound pressure. The SI unit of sound exposure is the pascal squared second (Pa2·s).
==Mathematical definition==
Sound exposure, denoted ''E'', is defined by
:E = \int_^ p(t)^2\, \mathrmt,
where
*the exposure is being calculated for the time interval between times ''t''0 and ''t''1;
*''p(t)'' is the sound pressure at time ''t'', usually A-weighted for sound in air.
