要約(英語): Hearing information is very important role in visual information limited. Sound source localization is nominated for particularly ability in a hearing information processing. Barn owls have excellent processing for hearing. We propose a hardware model which construct by auditory sense mechanism of barn owls. In this paper, we consider the model of external nucleus of the inferior colliculus (hereafter “ICx”), which locate the source of a sound by interaural time difference (hereafter “ITD”) for localization in the horizontal direction, and interaural level difference (hereafter “ILD”) for localization in the vertical direction. As a result, we show clearly that the detection position of an ITD model and detection position of an ILD model can converge. Also the output position of ICx model change with the position of sound source.
