Sound Exposure Level abbreviated as $SEL$ and $LAE$, is the total noise energy produced from a single noise event, expressed as a logarithmic ratio from a reference level.
Applicable units are those of quantitykind:SoundExposureLevel

$L_E = 10 \log_{10} \frac{E}{E_0} dB$, where $E$ is sound power and the reference value is $E_0 = 400 \mu Pa^2 s$.
