Abstract

Acoustic source localisation is the use of recorded information to determine the point of origin of a given sound. It has applications in military threat detection, forensics, and the study of environmental acoustics. Impulse responses recorded in a semi-enclosed urban environment have shown early reflections to be the dominant acoustic feature, with the majority of directional information present in the horizontal plane. This paper presents a source localisation algorithm that uses this information. Spatial Impulse Response Rendering analysis is used to extract reflection information from B-format impulse response measurements. Reverse ray-tracing is then used with a 2D geometric representation of the environment to estimate the source position. When used for recordings made in an enclosed and highly reverberant environment, the localisation performance suffers due to the lack of highly distinct early reflections.
