Acoustics - Audiometric test methods - Part 3: Speech audiometry (ISO 8253-3:2022)
SIST EN ISO 8253-3:2022

This document specifies basic methods for speech recognition tests for audiological applications.
NOTE       Examples of speech materials are given in Annex A.
In order to ensure minimum requirements of precision and comparability between different test procedures including speech recognition tests in different languages, this document specifies requirements for the composition, validation and evaluation of speech test materials, and the realization of speech recognition tests. This document does not specify the contents of the speech material because of the variety of languages.
Furthermore, this document also specifies the determination of reference values and requirements for the realization and manner of presentation. In addition, there are features of speech tests described which are important to be specified, but which are not understood as a requirement.
This document specifies procedures and requirements for speech audiometry with the recorded test material being presented by an audiometer through a transducer, e.g., an earphone, bone vibrator, or loudspeaker arrangement for sound field audiometry. Methods for using noise either for masking the non-test ear or as a competing sound are described.
Some test subjects, for example children, can require modified test procedures not specified in this document.
Specialized tests, such as those used for evaluating directional hearing and dichotic hearing, are outside the scope of this document.

Acoustics - Determination of sound immission from sound sources placed close to the ear - Part 2: Technique using a manikin (ISO 11904-2:2021)
SIST EN ISO 11904-2:2021

This document specifies basic framework measurement methods for sound immission from sound sources placed close to the ear. These measurements are carried out with a manikin, equipped with ear simulators including microphones. The measured values are subsequently converted into corresponding free-field or diffuse-field levels. The results are given as free-field related or diffuse-field related equivalent continuous A-weighted sound pressure levels. The technique is denoted the manikin technique.
This document is applicable to exposure to sound from sources close to the ear, for example during equipment tests or at the workplace to sound from earphones or hearing protectors with audio communication facilities.
This document is applicable in the frequency range from 20 Hz to 10 kHz. For frequencies above 10 kHz, ISO 11904-1 can be used.

It is applicable to all types of workplaces and all types of sources of sound which are met in workplaces, including human activities.
It includes those important strategies to adopt when buying a new machine or equipment.

Acoustics - Reference zero for the calibration of audiometric equipment - Part 7: Reference threshold of hearing under free-field and diffuse-field listening conditions (ISO 389-7:2019)
SIST EN ISO 389-7:2020

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.

Acoustics - Reference zero for the calibration of audiometric equipment - Part 1: Reference equivalent threshold sound pressure levels for pure tones and supra-aural earphones (ISO 389-1:2017)
SIST EN ISO 389-1:2018

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.

Acoustics - Statistical distribution of hearing thresholds related to age and gender (ISO 7029:2017)
SIST EN ISO 7029:2017

ISO 7029:2017 provides descriptive statistics of the hearing threshold deviation for populations of otologically normal persons of various ages under monaural earphone listening conditions. It specifies the following, for populations within the age limits from 18 years to 80 years for the range of audiometric frequencies from 125 Hz to 8 000 Hz:
a)    the expected median value of hearing thresholds given relative to the median hearing threshold at the age of 18 years;
b)    the expected statistical distribution above and below the median value.
For the frequencies from 3 000 Hz to 8 000 Hz, the median and statistical distribution for populations above 70 years are presented for information only.
ISO 7029:2017 also provides for information the expected median values at audiometric frequencies from 9 000 Hz to 12 500 Hz within the age limits from 22 years to 80 years.

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)
SIST EN 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.
