Acoustics — Audiometric test methods — Part 3: Speech audiometry

Edition date: 2022-01-18
In Force
Available languages: English, French
Summary:

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.



Le présent document spécifie les méthodes fondamentales d'essais de reconnaissance vocale pour les applications audiologiques.

NOTE            Des exemples de matériels vocaux sont donnés à l'Annexe A.

Afin de garantir l'existence d'exigences minimales de précision et de comparabilité entre différents modes opératoires d'essai, y compris pour des essais de reconnaissance vocale dans différentes langues, le présent document spécifie les exigences relatives à la composition, à la validation et à l'évaluation des matériels vocaux d'essai, ainsi qu'à la réalisation des essais de reconnaissance vocale. Le présent document ne spécifie pas le contenu du matériel vocal, en raison de la multiplicité des langues.

De plus, le présent document spécifie également la détermination de valeurs de référence et les exigences relatives à celle-ci, ainsi que le mode de présentation. Il existe en outre des caractéristiques des essais vocaux décrits qu'il est important de spécifier, mais qui ne sont pas considérées comme des exigences.

Le présent document spécifie des modes opératoires et des exigences applicables à l'audiométrie vocale, la présentation du matériel vocal d’essai enregistré s'effectuant au moyen d'un audiomètre, à l'aide d'un transducteur, par exemple, un écouteur ou un ossivibrateur, ou à l'aide de haut-parleurs pour l'audiométrie en champ acoustique. Il décrit des méthodes d'utilisation de bruits, soit comme bruits de masquage appliqués à l'oreille non testée, soit comme bruits de fond.

Pour certains sujets d’essai, par exemple les enfants, le recours à des modes opératoires d'essai modifiés, non spécifiés dans le présent document, peut se révéler nécessaire.

Les essais spécialisés, tels que ceux qui servent à évaluer l'audition directionnelle et l'audition dichotique, ne relèvent pas du domaine d'application du présent document.
