This part of ISO 389 specifies a standard reference zero for the scale of hearing threshold levelapplicable to pure-tone air conduction audiometers, in order to promote agreement and uniformity inthe expression of hearing threshold level measurements throughout the world.It states the information in a form suitable for direct application to the calibration of audiometers,that is, in terms of the reference equivalent threshold sound pressure levels of generic supra-auralearphones specified in 4.2, measured on an ear simulator complying with IEC 60318-1 and in terms oftype-specific data given in two additional tables for the IEC 60318-3 acoustic coupler and the IEC 60318-1 ear simulator respectively.The data are based on an assessment of the information available from the various standardizinglaboratories responsible for audiometric standards and from scientific publications.Some notes on the derivation and application of the reference levels are given in Annex B.
