AS ISO 389.5-2003
Acoustics - Reference zero for the calibration of audiometric equipment - Reference equivalent threshold sound pressure levels for pure tones in frequency range 8 kHz to 16 kHz
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. This Standard is identical with and reproduced from ISO/TR 389-5:1998.
