A Filter Model as Input Section of the ITD Model for Sound Source Localization in the Barn Owl

The sound localization of barn owls with respect to horizontal and vertical direction is based on analysis of the interaural differences in arrival time and the intensity of sound, respectively. So, we are studying the sound source localization system of birds in the field of engineering. In this paper we suggest a filter model, which analyzes algorithms in bird’s brains. The model outputs waveforms with information (time or intensity difference) by using a hardware neuron model. As a result, it is shown in the filter model that by changing the parameters of the synapse, information can be selected from the mixed signal.
