Abstract

La présente invention concerne un procédé d'adaptation précise d'un boîtier (1) d'un écouteur d'oreille (2) au niveau d'une oreille (3) d'une personne. Le boîtier repose par conformité de forme contre une face interne d'un tragus et contre une face interne d'un antihélix d'un pavillon de l'oreille (3). Dans une étape d'adaptation (9), un boîtier de référence (8), fabriqué dans une étape de préfabrication (7) et ayant une forme de boîtier de référence (6), est placé dans l'oreille (3) de la personne. Dans une étape de détection (10) suivant l'étape d'adaptation (9), un écart de forme (12) est déterminé entre la forme de boîtier de référence (6) et l'oreille (3) de la personne. Dans une étape de détermination (13) suivant l'étape de détection (10), sur la base de l'écart de forme (12) et de la forme de boîtier de référence (6), une forme de boîtier (14) du boîtier (1) est déterminée et, dans une étape de fabrication (15), le boîtier (1) présentant la forme de boîtier (14) est fabriqué. La présente invention concerne en outre un écouteur d'oreille (2).
