Abstract :
This paper presents a novel computational auditory model inspired by psycho acoustic and neurophysiological findings. The model utilizes the instantaneous difference between the two ear signals to predict spatial hearing cues that humans perceive. The main focus is on the interaural coherence cue, i.e. the perceived similarity between the waveforms of the ear signals. Simulations show that the proposed model is capable of predicting known psychoacoustical results
