Sound Exposure is the energy of the A-weighted sound calculated over the measurement time(s). For a given period of time, an increase of 10 dB(A) in sound pressure level corresponds to a tenfold increase in E.

Sound Exposure is the energy of the A-weighted sound calculated over the measurement time(s). For a given period of time, an increase of 10 dB(A) in sound pressure level corresponds to a tenfold increase in E.
$E = \int_{t1}^{t2}p^2dt$, where $t1$ and $t2$ are the starting and ending times for the integral and $p$ is the sound pressure.
