Le modèle binaural dans le domaine fréquentiel (FDBM) a déjà été proposé pour localiser plusieurs sources sonores. Étant donné que le procédé ne nécessite que deux signaux d'entrée et utilise des différences de phase et de niveau interaurales provoquées par la diffraction générée par la tête, la flexibilité d'application est très élevée lorsque la tête est considérée comme un objet. Lorsqu'un objet est symétrique par rapport aux deux microphones, les performances de localisation de la source sonore sont dégradées, car un être humain a une confusion avant-arrière due à la symétrie dans un plan médian. Cet article propose de réduire la dégradation des performances de localisation de la source sonore par une combinaison des sorties de la paire de microphones utilisant le FDBM. La méthode proposée est évaluée en l'appliquant à un système de caméra de sécurité, et les résultats ont montré une amélioration des performances dans la localisation des sources sonores grâce à la réduction du nombre de cônes de confusion.

Abstract: The frequency domain binaural model (FDBM) has been previously proposed to localize multiple sound sources. Since the method requires only two input signals and uses interaural phase and level differences caused by the diffraction generated by the head, flexibility in application is very high when the head is considered as an object. When an object is symmetric with respect to the two microphones, the performance of sound source localization is degraded, as a human being has front-back confusion due to the symmetry in a median plane. This paper proposes to reduce the degradation of performance on sound source localization by a combination of the microphone pair outputs using the FDBM. The proposed method is evaluated by applying to a security camera system, and the results showed performance improvement in sound source localization because of reducing the number of cones of confusion.
