Centre time

Another acoustic measurement parameter is the centre time, TS{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:

TS=0t h2(t)dt0h2(t)dt{T_{S}} =\frac{\int_{0}^{\infty}t \ h^{2}(t)\mathrm{d}t}{\int_{0}^{\infty}h^{2}(t)\mathrm{d}t}
