DIN EN ISO 389-5-2007 声学.测听设备校准用基准零点.第5部分:频率范围在8kHz~16kHz之间的纯音用标准等效阈声压级
Acoustics - Reference zero for the calibration of audiometric equipment - Part 5: Reference equivalent threshold sound pressure levels for pure tones in the frequency range 8 kHz to 16 kHz (ISO 389-5:2006); English version of DIN EN ISO 389-5:2007-05
This part of ISO 389 specifies reference equivalent threshold sound pressure levels(RETSPLs) of pure tones in the frequency range from 8 kHz to 16 kHz applicable to the calibration of air conduction audiometers for specific earphones.
NOTE Some notes and references on the derivation and the test conditions used to determine the reference levels are given in Annex A and the Bibiliography.
