Energy Decay Curve (EDC)

For measuring and defining reverberation time $ t_{60}$ , Schroeder introduced the so-called energy decay curve (EDC) which is the tail integral of the squared impulse response at time $ t$ :

$\displaystyle \hbox{EDC}(t) \mathrel{\stackrel{\mathrm{\Delta}}{=}}\int_t^\infty h^2(\tau)d\tau
$
