A method for simulating an artificial sound environment including sending an ultrasound reference signal to a headphone assembly worn by a user having two ears, the headphone assembly audibly providing at least one audio signal to each of the ears, processing arrival times of the ultrasound reference signal at each ear, so as to measure a phase difference of the signal as perceived by one ear in contrast to the other ear, modulating at least two audio signals, at least one signal for each ear, in accordance with the phase difference, and sending the at least two audio signals via the headphone assembly to each of the ears.
La présente invention concerne un procédé de simulation d'un environnement sonore artificiel. Ce procédé consiste à envoyer un signal ultrason de référence au casque d'écoute bilatérale porté par un utilisateur, le casque délivrant au moins un signal audio à chaque oreille. Le procédé consiste ensuite à traiter les temps d'arrivée du signal ultrason de référence à chacune des oreilles, de façon à mesurer le déphasage entre les perceptions du signal par chacune des oreilles. Le procédé consiste alors à moduler au moins les deux signaux audio, à raison d'au moins un signal pour chaque oreille, en tenant compte du déphasage, et enfin à envoyer aux deux oreilles les deux signaux audio via le casque d'écoute.
