By its position, ORISON uses the ear, anatomical amplifier : the pinna captures and spatializes2 sounds while the ear canal guides them to the eardrum ; then, the proximity of the eardrum allows an immediate restitution (< 0,8ms), for an optimal comfort even in the case of an unilateral fitting. Thus, ORISON allows :
- The 3D localization of sounds in space (use of the pinna) ;
- A restitution without delay of the amplified sounds (tympanic proximity) ;
- No amplification of parasitic noises (wind noise), the microphone being sheltered in the ear canal.
