EN 60318-5:2006

Electroacoustics - Simulators of human head and ear - Part 5: 2 cm³ coupler for the measurement of hearing aids and earphones coupled to the ear by means of ear inserts

Describes an acoustic coupler for loading an earphone or hearing aid with a specified acoustic impedance when determining its physical performance characteristics, in the frequency range 125 Hz to 8 kHz. It is suitable for air conduction hearing aids and earphones, coupled to the ear by means of ear inserts e.g. ear moulds or similar devices. The sound pressure developed by an earphone is not, in general, the same in the coupler as in a person's ear. However, it can be used as a simple and ready means for the exchange of specifications and of physical data on hearing aids and for the calibration of specified insert earphones used in audiometry. This first edition of IEC 60318-5 cancels and replaces IEC 60126:1973.

Electroacoustique - Simulateurs de tête et d'oreille humaines - Partie 5: Coupleur de 2 cm³ pour la mesure des appareils de correction auditive et des écouteurs couplés à l'oreille par des embouts

Décrit un coupleur acoustique destiné à adapter un écouteur ou un appareil de correction auditive avec une impédance acoustique spécifiée dans le domaine des fréquences comprises entre 125 Hz et 8 kHz, lors de la détermination de ses caractéristiques physiques. Elle s'applique aux appareils de correction auditive à conduction aérienne et aux écouteurs couplés à l'oreille au moyen d'embouts d'oreille, par exemple embouts moulés ou dispositifs similaires. La pression acoustique produite par un écouteur n'est généralement pas la même dans le coupleur et dans une oreille humaine. Cependant elle peut être utilisée en tant que moyen simple et immédiat pour l'échange de spécifications et de données physiques concernant les appareils de correction auditive et pour l'étalonnage des écouteurs à embout spécifiés utilisés en audiométrie. Cette première édition de la CEI 60318-5 annule et remplace la CEI 60126:1973.
