Acoustics - Reference zero for the calibration of audiometric equipment - Part 3: Reference equivalent threshold force levels for pure tones and bone vibrators (ISO 389-3:1994)
Specifies the following data applicable to the calibration of bone vibrators for pure-tone bone-conduction audiometry: reference equivalent threshold force levels (RETFL), corresponding to the threshold of hearing of young otologically normal persons by bone-conduction audiometry; essential characteristics of the bone vibrator and of its method of coupling to a person under test and to the mechanical coupler; essential characteristics and datum level of the masking noise applied to the ear not under test.

Dieser Teil der ISO 389 legt folgende für die Kalibrierung von Knochenleitungshörern in der Reinton-Knochenleitungs-Audiometrie anwendbare Daten fest: a)Äquivalente Bezugs-Schwellenkraftpegel, die den durch Knochenleitungs-Audiometrie bestimmten Hörschwellenpegeln von jungen, otologisch normalen Personen entsprechen. Der äquiva-lente Bezugs-Schwellenkraftpegel ist der Pegel der periodischen Kraft, die auf den mechanischen Kuppler mit bestimmten Eigenschaften (siehe 5.3) von einem Knochenleitungshörer übertragen wird,

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. Esch 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.
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 389-3 was prepared by Technical Committee
lSO/rC 43, Acoustics.
This first edition of ISO 389-3 cancels and replaces ISO 7566:1987, of
which it is a minor revision.
ISO 389 consists of the following Parts, under the general title Acoustics
- Reference zero for the calibration of audiometric equipment:
- Part 7: ßeference 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: ßeference equivalent threshold forte levels for pure tones
and bone Vibrators
- Part 4: Reference levels for narrow-band masking noise
- Part 5: Reference equivalent threshold Sound pressure levels for
pure tones in the frequency range 8 kHz to 16 kHz
- Part 6: Reference equivalent threshold Sound pressure levels for
acoustic test Signals of short duration

Introduction
Esch part of ISO 389 specifies a specific reference zero for the calibration
of audiometric equipment. ISO 389:1991 (to be re-issued as ISO 389-1)
and ISO 389-2 are applicable to audiometric equipment for the trans-
mission
