Le son 3D en aéronautique : applications et contraintes
National audience ; 3D sound belongs to new technologies being introduced in military pilots' helmet, dedicated to facilitate human-system interface.3D sound aims to reproduce, in the headset, the acoustic cues used by the auditory system to localize a sound source in space. Thanks to 3D sound technology, the operator can use his/her full auditory functions. In practical terms, spatializing sound data optimises their processing while relieving the cognitive load of the pilot, due to the intuitiveness of auditory perception. Thus, by restoring the direction and distance of virtual sound sources, 3D sound aids the detection and interpretation of alarms but also improves the intelligibility and the management of radio communications.After reminding the acoustic cues involved in sound localization, we introduce 3D sound technology and its potential applications. Then, the important issues raised by individual differences in spatial perception of sound sources are described. Given these individual differences, the solution of a specific perceptual learning is analyzed. Finally, because noise-induced hearing loss are frequent among aircrew, the impact of hearing loss on spatial sound perception is discussed. ; Le son 3D appartient aux nouvelles technologies en cours d'introduction dans les équipements de tête des pilotes d'aéronefs militaires, destinées à faciliter l'interface homme-système. La technologie son 3D vise à restituer sous casque les indices acoustiques utilisés par le système auditif pour localiser une source sonore dans l'espace. L'intérêt de cette technologie est de redonner à l'opérateur le plein usage de ses facultés auditives.En pratique, spatialiser les informations sonores optimise leurs traitements tout en épargnant la charge cognitive du sujet grâce à l'intuitivité de la perception auditive. Ainsi, en restituant la direction et la distance de sources sonores virtuelles, le son 3D favorise la détection et l'interprétation des alarmes mais aussi l'intelligibilité et la gestion des communications ...
