    Abstract

    We can estimate direction of arrival (DOA) or source location for many sound sources using just two ears, because we use fundamentally interaural time difference (ITD) and interaural level difference (ILD), and use sophisticatedly the spectral cues based on features of sounds reflected by his/her ear lobes, head or body, i.e., head-related transfer function (HRTF). We can also estimate DOA or source location by just single ear from an experience. In this paper, we propose a new DOA or source location estimation method using single microphone and single concave curved reflector. We make a database consisting of template impulse responses around reflector, i.e., reflector-related transfer function (RRTF). We call these template profiles, which are associated with sound source locations. The received sound is identified among template profiles, and we can estimate DOA or sound source location. We was able to provide a rough estimation of source location in experiments.
