Annotation of standard text IEC 61669-ed.2.0 :
IEC 61669:2015 gives recommendations and requirements for the measurement and estimation of the real-ear acoustical performance characteristics of air-conduction hearing aids and for the measurement of certain acoustic properties of the ear related to the application of hearing aids. Measurements of real-ear acoustical characteristics of hearing aids which apply non-linear or analytical processing techniques are valid only for the test signals used and conditions employed. The purpose of this standard is to ensure that measurements of real-ear acoustical performance characteristics of a given hearing aid on a given human ear can be replicated in other locations with other test equipment. This second edition cancels and replaces the first edition of IEC 61669:2001 and the first edition of ISO 12124:2001. This edition constitutes a technical revision. LIEC 61669:2015 donne les recommandations et les exigences relatives au mesurage et a lestimation des caracteristiques de performances acoustiques sur une oreille reelle des appareils de correction auditive a conduction aerienne, et au mesurage de certaines proprietes acoustiques de loreille liees a lapplication des appareils de correction auditive. Les mesurages des caracteristiques acoustiques des appareils de correction auditive sur une oreille reelle qui appliquent des techniques operatoires non lineaires ou analytiques sont valables uniquement pour les signaux d essai utilises et les conditions experimentales. La presente norme a pour objet de sassurer que les mesurages des caracteristiques de performances acoustiques sur une oreille reelle dun appareil de correction auditive donne, effectues sur une oreille humaine donnee peuvent etre repetes dans d autres emplacements avec un autre appareillage dessai. Cette deuxieme edition annule et remplace la premiere edition de lIEC 61669:2001 et la premiere edition de lISO 12124:2001. Cette edition consiste en une revision technique.
