La présente partie de l'ISO 389 prescrit un zéro normal de référence pour l'échelle des niveaux liminaires d'audition, applicable aux audiomètres à sons purs en conduction aérienne, en vue de promouvoir la concordance et l'uniformité d'expression des mesurages des niveaux liminaires d'audition dans le monde.Elle expose les données sous une forme se prêtant à leur application directe et à l'étalonnage des audiomètres, c'est-à-dire sous forme de réponse de deux modèles types d'écouteurs, mesurés sur un coupleur selon la CEI 60303, et sous forme d'autres écouteurs supra-auraux dont les caractéristiques sont prescrites en 4.3 et mesurées sur une oreille artificielle conformément à la CEI 60318.La présente Norme internationale est basée sur l'évaluation des informations recueillies auprès de divers laboratoires d'étalonnage responsables de normes audiométriques et extraites de publications scientifiques.Des commentaires sur la détermination et l'application des niveaux de référence recommandés sont donnés dans l'annexe A.
