Electroacoustics - Hearing aids - Part 0: Measurement of the performance characteristics of hearing aids
IEC 60118-0:2015 gives recommendations for the measurement of the performance characteristics of air conduction hearing aids based on a free field technique and measured with an acoustic coupler. This third edition cancels and replaces the second edition published in 1983 and its Amendment 1:1994 as well as IEC 60118-1:1995, Amendment 1:1998, IEC 60118-2:1983, Amendment 1:1993, Amendment 2:1997 and IEC 60118-6:1999. This edition constitutes a technical revision.

L'IEC 60118-0:2015 donne des recommandations pour la mesure des caractéristiques fonctionnelles des appareils de correction auditive à conduction aérienne, fondée sur une technique en champ acoustique libre utilisant un coupleur acoustique. Cette troisième édition annule et remplace la deuxième édition parue en 1983 et son Amendement 1:1994, l'IEC 60118-1:1995, l'Amendement 1:1998, l'IEC 60118-2:1983, l'Amendement 1:1993, l'Amendement 2:1997 et l'IEC 60118-6:1999. Cette édition constitue une révision technique.
Elektroakustika - Slušni aparati - Meritve tehničnih karakteristik slušnih aparatov
Ta del standarda IEC 60118 podaja priporočila za meritve tehničnih karakteristik slušnih aparatov, ki delujejo na podlagi prevajanja zvoka po zraku in ki temeljijo na tehniki prostega polja (free field technique) ter so izmerjene s pomočjo akustičnega spojnika.
Ta del standarda IEC 60118 velja za meritve in ocenjevanje elektroakustičnih karakteristik slušnih aparatov za potrebe, na primer, tipskega preskušanja in tehničnih listov proizvajalca.
Rezultati preskusov, pridobljeni z metodami, ki so navedene v tem delu standarda IEC 60118, prikazujejo delovanje v preskusnih pogojih in lahko znatno odstopajo od delovanja slušnega aparata v dejanskih pogojih uporabe.
Ta del standarda IEC 60118 uporablja akustični spojnik skladno s standardom IEC 60318-5, ki obremeni slušni aparat z določeno akustično impedanco in ne spreminja zvočnega tlaka v ušesu. Rezultati, pridobljeni z uporabo tega akustičnega spojnika, se bodo razlikovali od tistih, ki so pridobljeni z uporabo simulatorja zamašenega ušesa, zajetega v standardu IEC 60318-4, kot jo določajo starejše različice standarda IEC 60118-0.
Za meritev tehničnih karakteristik slušnih aparatov v simuliranih pogojih na kraju uporabe lahko uporabite standard IEC 60118-8. Za meritev karakteristik slušnih aparatov z običajnimi uporabniškimi nastavitvami in z uporabo govoru podobnega signala lahko uporabite standard IEC 60118-15.
Za meritev tehničnih karakteristik slušnih aparatov za namene zagotavljanja kakovosti pri izdelavi, dobavi in dostavi lahko uporabite standard IEC 60118-7. Frekvenčni razpon je v tem delu standarda IEC 60118 razširjen na 8 kHz v primerjavi s standardom IEC 60118-7, kjer je bil omejen na 5 kHz.
Čeprav je število meritev, ki jih zajema ta del standarda IEC 60118, omejeno, vse tu opisane meritve niso obvezne.
V primeru instrumentov za vstavitev v uho, ki so narejeni po meri, podatki, ki jih zagotovi proizvajalec, veljajo samo za določen slušni aparat, ki se ga preskuša.
