The IACC maximum value estimates interaural coherence between the two ear signals

Evidence

The IACC function is normalized with the power of signals, which means that it attains the value one only when the ear canal signals differ by the amount of the ITD and the ILD in the natural range, otherwise it gets a lower, non-negative value. The maximum value can thus be used to estimate the interaural coherence (Faller and Merimaa, 2004). — Ville Pulkki, Matti Karjalainen, Communication Acoustics- An…, 1668
