• Abstract:Human brain provides an accurate and energy efficient function for localizing sound sources. In order to build a localizing system with similar advantages, a biologically plausible spiking model for interaural level difference (ILD) processing auditory pathway from cochlea to the inferior colliclus in human brain is proposed in this paper. The biological plausibility is based on the facts that all nodes in the model are implemented as the Integrate-and-Fire neurons, it does not utilize complex mathematical functions, and the architecture bears a high resemblance to the physiological structure. A one-shot learning algorithm characterized as simple and fast is designed to construct the synapse weights between the lateral superior olive and the inferior colliclus in order to render the proposed model to produce expected responses for different azimuthal angles of sounds. Some simulation results are presented to demonstrate the abilities of the proposed model to identify the angle of the input stereo sound and to distinguish multiple sounds coming from different angles. It is also shown that the proposed model behaves in the way that is in high accordance with former physiological and psychoacoustic conclusions.
