(Main)IEC reference coupler for the measurement of hearing aids using earphones coupled to the ear by means of ear inserts
IEC reference coupler for the measurement of hearing aids using earphones coupled to the ear by means of ear inserts
Describes a coupler for loading the earphone with a specified acoustic impedance when determining the physical performance characteristics, in the frequency range 200 Hz to 5 000 Hz, of air-conduction hearing aids using earphones coupled to the ear by means of ear inserts, e.g. ear moulds or similar devices. The use of this coupler does not allow the actual performance of a hearing aid on a person to be obtained. Its use is recommended as a simple and ready means for the exchange of specifications and of physical data on hearing aids.
IEC-Bezugs-Kuppler für die Messung der akustischen Eigenschaften von Hörhilfen, deren Hörer mit Hilfe von Ohrpaßstücken an das Ohr angekoppelt werden
Coupleur de référence de la CEI pour la mesure des appareils de correction auditive utilisant des écouteurs couplés à l'oreille par des embouts
Décrit un coupleur destiné à charger l'écouteur à l'aide d'une impédance acoustique spécifiée afin de déterminer les caractéristiques physiques dans la bande de fréquences comprise entre 200 Hz et 5 000 Hz des appareils de correction auditive à conduction aérienne utilisant des écouteurs couplés à l'oreille au moyen d'embouts, par exemple des embouts moulés ou autres embouts similaires. L'utilisation de ce coupleur ne permet pas de déterminer la caractéristique réelle d'un appareil de correction auditive porté par une personne: il a pour objet de faciliter l'échange des spécifications et des caractéristiques physiques relatives aux appareils de correction auditive. La réalisation est illustrée à l'aide de dessins cotés.
