This paper proposed a lateralization method of speech sounds that had no restrictions with regard to sound field conditions, including the stationary and moved multisignals under the real circumstance. It is specially designed to model the space perception function of the human auditory system , which is the basis for the further binaural processing method such as COCKTAIL PARTY PROCESSOR. This important aim was achieved by applying the knowledge of binaural space perception of the human auditory system. Combining the crosscorrelation processing between binaural channels with the distributing characteristics of the location information of the different sound sources, a integrating processing unit of the location information in the different auditory channels was introduced in this pa per,then a composite judgement unit was introduced to simulate the location judgement function of the central nerve system. The individual steps of the processing scheme were described and preliminary results were presented.
