Abstract

This paper presents an analytic method for determining the orientation of a directional sound source in three-dimensional space using the source position, directivity and multi-microphone recordings. The acoustic signal emitted by the source is assumed to be broadband, such as a down-swept frequency modulated chirp of the kind many bats use while echolocating. The method has been tested in simulations on PC using the directivity of a piston transducer and the more complex and more realistic head-related transfer function of the Phyllostomus discolor bat. The ultimate purpose of the work is to determine the orientation and actual emitted call of a flying bat from a remote array recording.
