Abstract

L'invention concerne des procédés et dispositifs améliorés qui simulent la transmission du son de sources sonores vers les conduits auditifs d'un auditeur, ces sources étant disposées arbitrairement en trois dimensions par rapport à cet auditeur. Elle concerne en particulier des procédés nouveaux et améliorés permettant de mesurer des fonctions de transfert concernant une tête, des fonctions de transfert nouvelles et améliorées concernant une tête, des procédés nouveaux et améliorés permettant de traiter de telles fonctions et des procédés nouveaux permettant de modifier ou maintenir les directions des sources sonores telles que perçues par l'auditeur. Ces procédés de mesure sont améliorés pour qu'il soit maintenant possible de mesurer et/ou construire des fonctions de transfert concernant une tête pour lesquelles les descriptions de domaines temporels sont étonnamment courtes et pour lesquelles les différences entre individus sont étonnamment faibles. On peut exploiter ces nouvelles fonctions de transfert dans toute application concernant la simulation d'une transmission sonore, par exemple la simulation accoustique des salles de concert, la mesure, la simulation ou la reproduction des sons, telle que la synthèse binaurale, par exemple pour produire avec deux sources sonores, telles qu'un casque ou deux haut-parleurs, l'impression qu'a un auditeur d'écouter un son produit par un système sonore multivoie, tel qu'un système 'surround', quadriphonique, stéréophonique, etc., pour la conception de filtres électroniques utilisés par exemple dans des systèmes à réalité virtuelle afin de simuler l'émission sonore d'une source sonore virtuelle vers les conduits auditifs de l'auditeur, ou bien pour la conception d'une tête artificielle prévue pour que ses fonctions de transfert se rapprochent autant que possible de celle de l'invention. Ceci permet de représenter les humains au mieux grâce à cette tête artificielle, par exemple pour réaliser des enregistrements de qualité optimum avec une tête artificielle.
