Foreword
ISO (the International Organization for Standardization) is a worldwide
federation of national standards bodies (ISO member bodies). The work of
preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which
a technical committee has been established has the right to be represented
on that committee. International organizations, governmental and non-
governmental, in liaison with ISO, also take part in the work. ISO
collaborates closely with the International Electrotechnical Commission
(IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with ISO/IEC Directives,
Part 3.
Draft International Standards adopted by the technical committees are
circulated to the member bodies for voting. Publication as an International
Standard requires approval by at least 75 % of the member bodies casting
a vote.
International Standard ISO 389-1 was prepared by Technical Committee
ISO/TC 43, Acoustics.
This first edition cancels and replaces ISO 389:1991. It is a minor revision
in order to make it part of the ISO 389 series.
ISO 389 consists of the following parts, under the general title Acoustics —
Reference zero for the calibration of audiometric equipment:
— Part 1: Reference equivalent threshold sound pressure levels for pure
tones and supra-aural earphones
— Part 2: Reference equivalent threshold sound pressure levels for pure
tones and insert earphones
— Part 3: Reference equivalent threshold force levels for pure tones and
bone vibrators
— Part 4: Reference levels for narrow-band masking noise

Introduction
Each part of ISO 389 specifies a specific reference zero for the calibration
of audiometric equipment. The present part 1 is applicable to audiometric
equipment for the transmission of pure tones by air conduction and
supra-aural earphones. ISO 389-2 is applicable to audiometric equipment
for the transmission of pure tones by air conduction and inser
