DESCRIPTION

BS EN 60318-6:2008


This standard BS EN 60318-6:2008 Electroacoustics. Simulators of human head and ear is classified in these ICS categories:
  • 17.140.50 Electroacoustics
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 person's 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.
