摘要：
In this paper we describe an implementation of a part of binaural sound localization system, which uses Interaural Time Differences (ITDs). All neurons are simulated by a spike response model, which includes postsynaptic potentials (PSPs) and refractory period. A winner-take-all (WTA) network selects the dominant source from the representation of the sound's angles of incidence. At the beginning, we explain the principles of the localization system, and then details of implementation of its input part: Inner Hair Cells (IHCs), responsible for transforming input sound signals into spikes.
