Annotation of standard text IEC 60318-6-ed.1.0 :
Describes a mechanical coupler for the measurement of the output force of bone vibrators. The mechanical impedance of the coupler is specified in the frequency range 125 Hz to 8 000 Hz. The coupler is intended for calibration of audiometers using bone vibrators having a plane circular tip area of 175 mm2 ± 25 mm2 and for determining the performance of bone conduction hearing aids. The vibratory force developed by a bone vibrator is not, in general, the same on the coupler as on a persons mastoid. However, the IEC recommends its use as a means for the calibration of specified vibrators used in audiometry and for the exchange of specifications and of data on bone conduction hearing aids. This standard cancels and replaces IEC 60373 published in 1990. This first edition constitutes a technical revision. Decrit un coupleur mecanique destine a la mesure de la force de sortie des ossivibrateurs. Limpedance mecanique du coupleur est specifiee dans la gamme de frequences comprise entre 125 Hz et 8 000 Hz. Le coupleur est destine a letalonnage des audiometres utilisant les ossivibrateurs dont lextremite presente une surface plane et circulaire de 175 mm2 ± 25 mm2 et a la determination de la performance des appareils de correction auditive a conduction osseuse. La force vibratoire developpee par un ossivibrateur nest pas, en general, la meme sur le coupleur que sur la mastoide dune personne. Cependant, la CEI recommande son utilisation comme moyen detalonnage des vibrateurs specifies, utilises en audiometrie et pour lechange des specifications et des donnees sur les appareils de correction auditive a conduction osseuse. La presente norme annule et remplace la CEI 60373 parue en 1990. Cette premiere edition constitue une revision technique.
