Acoustics - Reference zero for the calibration of audiometric equipment - Part 3: Reference equivalent threshold vibratory force levels for pure tones and bone vibrators (ISO 389-3:2016)
ISO 389-1:2016 specifies the following data applicable to the calibration of bone vibrators for pure-tone bone-conduction audiometry:
a) reference equivalent threshold vibratory force levels (RETVFL), corresponding to the threshold of hearing of young otologically normal persons by bone-conduction audiometry;
b) essential characteristics of the bone vibrator and the method of coupling to the test subject, and to the mechanical coupler;
c) essential characteristics of the masking noise and the baseline masking noise level applied to the ear not under test.
Guidance on the practical application of this part of ISO 389 in the calibration of audiometers is given in Annex B.
RETVFL is the vibratory force level transmitted to a mechanical coupler of specified characteristics by a vibrator when applied to the mechanical coupler under stated conditions of test and when energized at the voltage level corresponding to the normal threshold of hearing for location on the mastoid prominence.
NOTE 1 Values for the differences in reference equivalent threshold vibratory force levels between location on the forehead and mastoid are included for information in Annex C.
NOTE 2 Recommended procedures for carrying out bone-conduction audiometry are specified in ISO 8253‑1.
Akustik - Standard-Bezugspegel für die Kalibrierung audiometrischer Geräte - Teil 3: Äquivalente Bezugs-Schwellenkraftpegel für reine Töne und Knochenleitungshörer (ISO 389-3:2016)
Dieser Teil von ISO 389 legt die folgenden, für die Kalibrierung von Knochenleitungshörern in der Reinton-Knochenleitungs-Audiometrie anwendbaren Daten fest:
a) Äquivalente Bezugs-Schwellenkraftpegel (RETVFL), die den durch Knochenleitungs-Audiometrie bestimmten Hörschwellenpegeln von jungen, otologisch normalen Personen entsprechen;

c) Wesentliche Eigenschaften und der Grundpegel des Verdeckungsgeräuschs, mit dem das nicht geprüfte Ohr beschallt wird.
Anleitung zur praktische Anwendung dieses Teils von ISO 389 bei der Kalibrierung von Audiometer ist im Anhang B enthalten.
Der Bezugs-Schwellenpegel der periodischen Kraft ist der vibratorische Wert der Kraft auf einen mechanischen Kuppler mit festgelegten Eigenschaften, die über einen Vibrator, wenn ein mechanischen Kuppler mit festgelegten Prüfbedingungen verwendet wird, auf diesen wirkt und dieser mit einer Spannung, die den üblichen Hörschwellen für die Stelle entspricht, betrieben, am vorstehenden Teil des Mastoids angewendet wird.

Le niveau de référence équivalent de force vibratoire liminaire (RETVFL) est le niveau de la force vibratoire transmise à un coupleur mécanique de caractéristiques spécifiées par un vibrateur lorsque ce dernier est appliqué sur le coupleur mécanique dans des conditions d'essai spécifiées et lorsqu'il est excité à un niveau de tension correspondant au seuil normal d'audition pour un emplacement sur l'apophyse mastoïde.
NOTE 1 Les valeurs correspondant à la différence de niveau de référence équivalent de force vibratoire liminaire entre l'emplacement sur le front et l'emplacement sur l'apophyse mastoïde de l'ossivibrateur sont données à titre d'information en Annexe C.
NOTE 2 L'ISO 8253‑1 spécifie des modes opératoires recommandés pour réaliser les essais audiométriques en conduction osseuse.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or

This second edition cancels and replaces the first edition (ISO 389-3:1994), which has been technically
revised. It also incorporates the Technical Corrigendum ISO 389-3:1994/Cor 1:1995.
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 vibratory 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.
ISO 389-1, ISO 389-2 and ISO 389-8 are applicable to audiometric equipment for the transmission of
pure tones by air conduction.
For clinical diagnostic and other audiometric purposes, it is often necessary to compare the measured
