Acoustics - Audiometric test methods - Part 3: Speech audiometry (ISO 8253-3:2012)
ISO 8253-3:2012 specifies basic methods for speech recognition tests for audiological applications.
In order to ensure minimum requirements of precision and comparability between different test procedures including speech recognition tests in different languages, ISO 8253-3:2012 specifies requirements for the composition, validation and evaluation of speech test materials, and the realization of speech recognition tests. ISO 8253-3:2012 does not specify the contents of the speech material because of the variety of languages.
Furthermore, ISO 8253-3:2012 also specifies the determination of reference values and fulfilment requirements for the realization and manner of presentation.
ISO 8253-3:2012 specifies procedures and requirements for speech audiometry with the recorded test material being presented by air conduction through an earphone, or from a loudspeaker 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 amended test procedures not specified in ISO 8253-3:2012.
Specialized tests such as those used for evaluating directional hearing and dichotic hearing are outside the scope of ISO 8253-3:2012.
Akustik - Audiometrische Prüfverfahren - Teil 3: Sprachaudiometrie (ISO 8253-3:2012)
Dieser Teil von ISO 8253 beschreibt grundlegende Verfahren für in der Audiologie angewandte Sprachverständlichkeitstests.
Im Hinblick auf die Vielzahl der Sprachen legt ISO 8253-3 nicht die Inhalte der einzelnen Sprachmaterialien
fest. Um sicherzustellen, dass Mindestanforderungen hinsichtlich der Genauigkeit und der Vergleichbarkeit
zwischen verschiedenen Testverfahren - einschließlich Sprachverständlichkeitstests in verschiedenen Sprachen
- eingehalten werden, beschreibt diese Norm Anforderungen an die Zusammensetzung, Validierung
und Auswertung von Sprachtestmaterialien und an die Realisierung von Sprachverständlichkeitstests.
Weiterhin beschreibt diese Norm, wie Bezugswerte zu bestimmen sind und welche Anforderungen an die
Realisierung und die Art der Darbietung erfüllt werden müssen.
Dieser Teil von ISO 8253 legt Verfahren und Anforderungen für die Sprachaudiometrie mit aufgezeichnetem
Sprachtestmaterial fest, das über Luftleitung durch einen Kopfhörer, über Knochenleitung durch einen Knochenleitungshörer
oder über einen Lautsprecher für die Schallfeldaudiometrie angeboten wird. Die Verfahren
für den Einsatz von Rauschen, entweder zur Verdeckung am nichtgeprüften Ohr oder als Zusatzschall, werden
beschrieben. Alle Prüfverfahren beruhen auf der Verwendung offener Prüfmaterialien.
Einige Probanden, z. B. Kinder, können geänderte Prüfabläufe erfordern, die nicht in diesem Teil von
ISO 8253 festgelegt sind.
Dieser Teil von ISO 8253 legt keine speziellen Prüfverfahren fest, wie sie für die Bestimmung des Richtungshörens
und des dichotischen Hörens verwendet werden.

Akustika - Avdiometrijske preskusne metode - 3. del: Govorna avdiometrija (ISO 8253-3:2012)
Ta del standarda ISO 8253 določa osnovne preskusne metode za prepoznavanje govora za avdiološke naprave. Za zagotovitev minimalnih zahtev glede natančnosti in primerljivosti med različnimi preskusnimi postopki, vključno s preskusi prepoznavanja govora v različnih jezikih, ta del standarda ISO 8253 določa zahteve za sestavo, validacijo in vrednotenje gradiva za preskus govora ter izvedbo preskusov prepoznavanja govora. Ta del standarda ISO 8253 zaradi različnih jezikov ne določa vsebine govornega gradiva. Ta del standarda ISO 8253 določa tudi referenčne vrednosti ter izpolnjevanje zahtev za izvedbo in obliko predstavitve. Ta del standarda ISO 8253 določa postopke in zahteve za govorno avdiometrijo, pri čemer je posneto preskusno gradivo predstavljeno s prevajanjem po zraku prek slušalk ali zvočnika pri avdiometriji zvočnega polja. Opisane so metode za uporabo hrupa kot sredstva za zakrivanje ušesa, ki ne sodeluje pri preskusu, ali kot konkurenčnega zvoka. Pri nekateri preskuševalcih, na primer otrocih, so mogoče potrebni prilagojeni preskusni postopki, ki niso določeni v tem delu standarda ISO 8253. Specializirani preskusi, kot so preskusi, ki se uporabljajo za vrednotenje usmerjenega sluha in razdeljenega sluha, niso zajeti v tem delu standarda ISO 8253.
