Centre time

Another acoustic measurement parameter is the centre time, ${T_{S}}$, represents the time of the centre of gravity of the squared impulse response [1]. It can be measured, in seconds, using the following equation:

$${T_{S}} =\frac{\int_{0}^{\infty}t \ h^{2}(t)\mathrm{d}t}{\int_{0}^{\infty}h^{2}(t)\mathrm{d}t}$$
