Binaural analysis of a sound source

Category (2). The Localization of sound sources is one of the most important functions in the auditory system. In this paper we propose a model that simulates the localization process of sound sources in the human being; with a binaural treatment of audible signals captured by standard microphones and conventional PC sound card in a (reverberant) regular environment, we attempt to give a more clear understanding about the issues of locate the audible sources, and the concepts used in the digital processing systems, as cross correlation, Fourier analysis, among others. Besides, we will be able to create software tools that allows us to improve research and in the same time, it may clarify concepts in an interactive and accesible way. The three keys of audible location used in this project, are enough and even redundant in the determination about the orientation of the source in the azimuthal plane. Although the determination effects of distances, angular resolution and forward-backward distinction are weak compared with the real audible sensation, despite of the work with signals taken by the dummy head with and without pinna Perhaps there are other keys, ones that can play a essential part in this matters.
