Annotation of standard text IEC 60118-15-ed.1.0 :
IEC 60118-15:2012 specifies a test signal designed to represent normal speech, the International Speech Test Signal (ISTS), together with the procedures and the requirements for measuring the characteristics of signal processing in air-conduction hearing aids. The measurements are used to derive the estimated insertion gain (EIG). For the purposes of characterizing a hearing aid for production, supply and delivery, the procedures and requirements to derive the coupler gain on a 2 cm3 coupler as defined in IEC 60318-5 are also specified. The purpose of this standard is to ensure that the same measurements made on a hearing aid following the procedures described, and using equipment complying with these requirements, give substantially the same results. Measurement methods that take into account the acoustic coupling of a hearing aid to the individual ear and the acoustic influence of the individual anatomical variations of an end-user on the acoustical performance of the hearing aid, known as real-ear measurements, are outside the scope of this particular standard. La CEI 60118-15:2012 specifie un signal dessai concu pour representer la parole normale, le signal vocal international de test (ISTS), ainsi que les procedures et les exigences relatives a la mesure des caracteristiques de traitement des signaux dans les appareils de correction auditive a conduction aerienne. Les mesures sont utilisees pour obtenir le gain dinsertion estime (EIG, estimated insertion gain). Pour les besoins de la caracterisation dun appareil de correction auditive aux fins de production, de livraison et dapprovisionnements, les procedures et exigences pour obtenir le gain de coupleur a laide dun coupleur de 2 cm3 tel que defini dans la CEI 60318-5 sont egalement specifiees. Le but de la presente norme est de garantir que les memes mesures effectuees sur un appareil de correction auditive en suivant les procedures decrites, et en utilisant lappareillage conformement a ces exigences, donnent pratiquement les memes resultats. Les methodes de mesure qui tiennent compte du couplage acoustique dun appareil de correction auditive a loreille individuelle et de linfluence acoustique des variations anatomiques individuelles dun utilisateur final sur les performances acoustiques de lappareil de correction auditive, connues sous le nom de mesures doreille reelle, sont en dehors du domaine dapplication de la presente norme particuliere.
