BS EN ISO 389-1:2018 specifies a standard reference zero for the scale of hearing threshold level applicable
to pure-tone air conduction audiometers, to promote agreement and uniformity in the 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-aural earphones
specified in 4.2, measured on an ear simulator complying with IEC 60318-1 and in terms of modelspecific
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 standardizing
laboratories responsible for audiometric standards and from scientific publications.
