Popis

BS EN 60318-3:2015


This standard BS EN 60318-3:2015 Electroacoustics. Simulators of human head and ear is classified in these ICS categories:
  • 17.140.50 Electroacoustics
  • 13.140 Noise with respect to human beings

This part of IEC 60318 specifies an acoustic coupler for the measurement of supra-aural audiometric earphones in the frequency range from 125 Hz to 8 000 Hz.

The sound pressure developed by an earphone is not, in general, the same in the coupler as in a person's ear. However, the acoustic coupler can be used as an objective and reproducible means of measuring the output of supra-aural earphones. It can be used for specifying reference equivalent threshold sound pressure levels (RETSPL) for the calibration of audiometers.
