NF C97-611

Occluded-ear simulator for the measurement of earphones coupled to the ear by ear inserts.

Cette norme décrit un simulateur d'oreille occluse destiné à la mesure des écouteurs couplés à l'oreille par des embouts. Ce simulateur doit être utilisé notamment pour effectuer certaines des mesures décrites dans la NF C 97-610 "Appareils de correction auditive. Définitions et méthodes de mesure". Une annexe (non normative) indique les valeurs des niveaux de pression acoustique relevés avec le coupleur de 2 cm3 de la Publication 126 de la IEC, par rapport à celles relevées dans le simulateur d'oreille occluse.
