Acoustics - Reference zero for the calibration of audiometric equipment - Part 6: Reference threshold of hearing for test signals of short duration (ISO 389-6:2007); English version of DIN EN ISO 389-6:2007-10
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.
