Abstract
La présente invention concerne un casque acoustique (10) comprenant : - deux modules acoustiques (12), chaque module acoustique (12) comprenant un transducteur (20) propre à transmettre un signal sonore, caractérisé en ce que chaque module acoustique (12) comprend deux microphones (22) configurés pour recevoir un signal sonore, à chaque microphone (22) étant associée une fonction de transfert, et en ce que le casque (10) comprend un module de traitement configuré pour calculer pour chaque module acoustique (12) : • pour chaque microphone (22), un produit de convolution d'un signal sonore reçu par ledit microphone (22) avec la fonction de transfert associée audit microphone (22), et • une combinaison linéaire des produits de convolution calculés pour les microphones (22) dudit module acoustique (12), un transducteur (20) de chaque module acoustique (12) étant configuré pour générer un signal sonore dépendant de la combinaison linéaire calculée pour le module acoustique (12) correspondant.
