Abstract
A model for the auditory localization of multiple sound sources is developed and evaluated. This model is more flexible than previous localization models because sources are not confined to specific positions within the horizontal plane. The model is restricted to sources which are stationary in time, including tones, coherent noise, and incoherent noise. The model produces a display of auditory image positions for given sound sources. Predictions of auditory image position made by the model are compared to data from the literature describing human perceptions. The information available on human perceptions include single and paired tone sources, paired pure tone and coherent noise sources in phase opposition, and paired sources with intersource time and level differences. The model produces image predictions which are consistent with perception data in all conditions except when intersource time differences are present between wide band coherent noise sources.
