Popis

BS EN ISO 389-6:2007


This standard BS EN ISO 389-6:2007 Acoustics. Reference zero for the calibration of audiometric equipment is classified in these ICS categories:
  • 13.140 Noise with respect to human beings

This part of ISO 389 specifies reference hearing threshold levels for tests signals of short duration applicable to the calibration of audiometric equipment where such signals are used.

NOTE 1 Some notes on different parameters and their effects on threshold levels are given in Annex A.

NOTE 2 Preferred test conditions for determining hearing thresholds for standardization are specified in ISO 389-9.
