Abstract

This work investigates the possibility of two regimes for background noise role in multisource or multisignal listening. In the first regime (low number of sources), the background noise is possibly constructive while in the other regime (high number of sources), the background noise is destructive, as is usually expected. The two regimes are separated by the optimal number of sources N_opt, where N_opt= 20 for mixing of delayed sources and N_opt = 10 for mixing of sources without delay. The existence of N_opt shows that the decrease in human listening performance in multisource conditions is possibly aided by the background noise in low number of sources.
