Electroacoustics - Simulators of human head and ear - Part 8: Acoustic coupler for high-frequency measurements of hearing aids and earphones coupled to the ear by means of ear inserts
IEC 60318-8:2022 describes an acoustic coupler for loading a hearing aid or insert earphone with a specified acoustic impedance when testing its acoustic performance, in the frequency range up to 16 kHz. It is suitable for air-conduction hearing aids and earphones, coupled to the ear by means of ear inserts, earmoulds or similar devices. The acoustic coupler does not simulate the human ear. However, it has an effective volume of only 0,4 cm3, which is small enough not to produce significant resonances in the coupler in the frequency range below 16 kHz. Therefore, it will load the earphone with a known acoustic impedance, which allows repeatable measurements with low uncertainty to be obtained on earphones used in extended high-frequency audiometry.

Electroacoustique - Simulateurs de tête et d'oreille humaines - Partie 8: Coupleur acoustique pour les mesurages à hautes fréquences des appareils de correction auditive et des écouteurs couplés à l’oreille par des embouts
L’IEC 60318-8:2022 décrit un coupleur acoustique permettant de charger un appareil de correction auditive ou un écouteur à insérer avec une impédance acoustique spécifiée lors de l'essai de ses performances acoustiques, dans la plage de fréquences allant jusqu'à 16 kHz. Il convient aux appareils de correction auditive et aux écouteurs à conduction aérienne, couplés à l'oreille par des inserts auriculaires, des embouts ou des appareils similaires. Le coupleur acoustique ne simule pas l'oreille humaine. Il a cependant un volume effectif de seulement 0,4 cm3, ce qui est suffisamment petit pour ne pas produire de résonances significatives dans le coupleur dans la plage de fréquences inférieure à 16 kHz. Il charge donc l'écouteur avec une impédance acoustique connue, ce qui permet d'obtenir des mesurages répétables avec une faible incertitude sur les écouteurs utilisés en audiométrie haute fréquence étendue.
Elektroakustika - Simulatorji človeške glave in ušes - 8. del: Akustični spojnik za visokofrekvenčne meritve slušnih pripomočkov in slušalk, ki so na ušesa pritrjeni z ušesnimi vstavki (IEC 60318-8:2022)
Ta del standarda IEC 60318 opisuje akustični spojnik za obremenitev slušnega pripomočka ali vtične ušesne slušalke z določeno akustično impedanco pri preskušanju akustičnih lastnosti takega izdelka, in sicer v frekvenčnem razponu do 16 kHz. Primeren je za zračno prevodne slušne pripomočke in vtične ušesne slušalke, ki se na uho pritrdijo s pomočjo ušesnih vstavkov, ušesnih vložkov ali podobnih pripomočkov. Akustični spojnik ne simulira človeškega ušesa. Toda njegova efektivna prostornina znaša le 0,4 cm3, kar pomeni, da je dovolj majhen, da v frekvenčnem razponu pod 16 kHz v njem ne pride do znatne resonance. Tako ušesno slušalko obremeni z znano akustično impedanco, ki omogoča ponovljive meritve z nizko stopnjo negotovosti, opravljene na slušalkah, ki se uporabljajo pri razširjeni visokofrekvenčni avdiometriji.
