What is ISO 389‑7 - Reference threshold of hearing for the calibration of audiometric equipment about? ISO 389 discusses acoustics for the reference zero for the calibration of audiometric equipment. ISO 389‑7 is an international standard on reference threshold of hearing under free-field and diffuse-field listening conditions for the calibration of audiometric equipment to minimize any measurement uncertainty ISO 389‑7 is the seventh part of a multi-part series that specifies a reference threshold of hearing for the calibration of audiometric equipment used under the following conditions. The sound field in the absence of the listener consists of either a free progressive plane wave (free field) or a diffuse sound field, as specified in ISO 8253-2. In the case of a free field, the source of sound is directly in front of the listener (frontal incidence) The sound signals are pure (sinusoidal) tones in the case of free-field conditions and one-third octave bands of (white or pink) noise in the case of diffuse-field conditions The sound pressure level is measured in the absence of the listener at the position where the center of the listener’s head would be Listening is binaural Note: The threshold data differ from the audiometric zero specified in ISO 389-1 , ISO 389-2 , ISO 389-5, and ISO 389-8 , since the latter refers to monaural listening through earphones with sound pressure levels referred to specified couplers and ear simulators. Direct comparison between the data in the parts of ISO 389 mentioned above and in this document is therefore not appropriate. Who is ISO 389‑7 - Reference threshold of hearin...

This document specifies a reference threshold of hearing for the calibration of audiometric equipment used under the following conditions. a) The sound field in the absence of the listener consists of either a free progressive plane wave (free field) or a diffuse sound field, as specified in ISO 8253‑2. In the case of a free field, the source of sound is directly in front of the listener (frontal incidence). b) The sound signals are pure (sinusoidal) tones in the case of free-field conditions and one-third-octave bands of (white or pink) noise in the case of diffuse-field conditions. c) The sound pressure level is measured in the absence of the listener at the position where the centre of the listener's head would be. d) Listening is binaural. NOTE 1 Correction values for the threshold of hearing under free-field listening conditions and selected angles of sound incidence (45° and 90°) deviating from frontal incidence are given in ISO 8253-2 for information. NOTE 2 Other conditions are given in Reference [1]. The data are given in numerical form for the preferred frequencies in the one-third-octave series from 20 Hz to 16 000 Hz inclusive in accordance with ISO 266 and, in addition, for some intermediate audiometric frequencies up to 18 000 Hz. The threshold data differ from the audiometric zero specified in ISO 389‑1, ISO 389‑2, ISO 389‑5 and ISO 389‑8, since the latter refer to monaural listening through earphones with sound pressure levels referred to specified couplers and ear simulators. Direct comparison between the data in the parts of ISO 389 mentioned above and in this document is therefore not appropriate.

ISO 389-1:2017 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. ISO 389-1:2017 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 model-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 standardizing laboratories responsible for audiometric standards and from scientific publications. Some notes on the application and derivation of the reference levels are given in Annexes A and B.

Community response to noise can vary differently among sound sources that are observed to have the same acoustic levels. This part of ISO 1996 describes adjustments for sounds that have different characteristics. The term “rating level” is used to describe physical sound predictions or measurements to which one or more adjustments have been added. On the basis of these rating levels, the long-term community response can be estimated. This part of ISO 1996 does not specify limits for environmental noise. NOTE 1 In acoustics, several different physical measures describing sound can have their level expressed in decibels (e.g. sound pressure, maximum sound pressure, and equivalent continuous sound pressure). The levels corresponding to these physical measures normally will differ for the same sound. This often leads to confusion. Therefore, it is necessary to specify the underlying physical quantity (e.g. sound pressure level, maximum sound pressure level, and equivalent continuous sound pressure level). NOTE 2 In this part of ISO 1996, quantities are expressed as levels in decibels. However, some countries validly express the underlying physical quantity, such as maximum sound pressure, in pascal or sound exposure in pascal-squared seconds. NOTE 3

This part of ISO 389 specifies the following data applicable to the calibration of bone vibrators for puretone 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; c) essential characteristics of the masking noise and the baseline masking noise level applied to the ear not under test. b) essential characteristics of the bone vibrator and the method of coupling to the test subject, and to the mechanical coupler; 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.

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; b) Wesentliche Eigenschaften des Knochenleitungshörers sowie die Methode zur Ankopplung an den Probanden und an den mechanischen Kuppler; 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. ANMERKUNG 1 Werte für die Unterschiede zwischen den äquivalenten Bezugs-Schwellenkraftpegeln bei Stirnankopplung und bei Mastoidankopplung sind zur Information in Anhang C angegeben. ANMERKUNG 2 Empfohlene Verfahren zur Durchführung der Knochenleitungs-Audiometrie sind in ISO 8253-1 beschrieben.
