In this paper we present a novel sound source localisation method that requires the spatial location of two sound sources to be matched by a listener. The method is aided by auditory feedback and effectively provides a measure of the minimum audible angle of the system under test. The number of front-back reversals and the time taken to localise each source are provided as additional indicators of performance. We demonstrate the application of our method by comparing localisation accuracy for a particular source with and without a secondary source present. The results demonstrate a small, but significant angular increase in the localisation error for the dual-source condition and also an increase in the time taken.
