Acoustics - Audiometric test methods - Part 2: Sound field audiometry with pure-tone and narrow-band test signals (ISO 8253-2:2009)
ISO 8253-2:2009 specifies relevant test signal characteristics, requirements for free, diffuse, and quasi‑free sound fields, and procedures for sound field audiometry using pure tones, frequency-modulated tones or other narrow-band test signals presented by means of one or more loudspeakers. The primary purpose is the determination of hearing threshold levels in the frequency range 125 Hz to 8 000 Hz, but this range can be extended to 20 Hz to 16 000 Hz.
ISO 8253-2:2009 does not include specifications for the use of hand-held loudspeakers. Speech as a test signal is not covered.
The purpose of ISO 8253-2:2009 is to ensure that tests of hearing, using sound field audiometry, give as high a degree of accuracy and reproducibility as possible.
Examples of graphical representations of the results are given.
Akustik - Audiometrische Prüfverfahren - Teil 2: Schallfeld-Audiometrie mit reinen Tönen und schmalbandigen Prüfsignalen (ISO 8253-2:2009)
Dieser Teil von ISO 8253 legt wesentliche Eigenschaften des Prüfsignals, Anforderungen an das freie, dif-fuse, und quasi-freie Schallfeld und Verfahren der Schallfeld-Audiometrie mit reinen Tönen, frequenzmodu-lierten Tönen oder anderen schmalbandigen Prüfsignalen fest, die über einen oder mehrere Lautsprecher dargeboten werden. Der hauptsächliche Verwendungszweck ist die Bestimmung von Hörschwellenpegeln im Frequenzbereich von 125 Hz bis 8 000 Hz. Dieser Bereich kann aber auf 20 Hz bis 16 000 Hz erweitert wer-den.
Dieser Teil von ISO 8253 enthält keine Festlegungen zur Verwendung von handgehaltenen Lautsprechern. Sprache als Prüfsignal wird hier nicht behandelt.
Der Zweck dieses Teils von ISO 8253 ist es, sicherzustellen, dass Hörprüfungen mittels Schallfeld-Audio-metrie höchstmögliche Genauigkeit und Reproduzierbarkeit ergeben.
Beispiele für die grafische Darstellung der Ergebnisse und Literaturhinweise werden in Anhang A angegeben.
Acoustique - Méthodes d'essais audiométriques - Partie 2: Audiométrie en champ acoustique avec des sons purs et des bruits à bande étroite comme signaux d'essai (ISO 8253-2:2009)
L'ISO 8253-2:2009 spécifie les caractéristiques utiles des signaux d'essai, les exigences relatives aux champs acoustiques libre, diffus et quasi libre, ainsi que les modes opératoires s'appliquant à l'audiométrie en champ acoustique réalisée à l'aide de sons purs, de sons modulés en fréquence ou d'autres signaux d'essai de bande étroite émis par un ou plusieurs haut-parleurs. L'objectif principal est la détermination des niveaux liminaires d'audition dans la gamme de fréquences comprises entre 125 Hz et 8 000 Hz, celle-ci pouvant être étendue entre 20 Hz et 16 000 Hz.
L'ISO 8253-2:2009 ne comporte pas de spécifications relatives à l'utilisation de haut-parleurs portatifs. Elle ne couvre pas les essais vocaux.
L'objectif de l'ISO 8253-2:2009 est de garantir un degré de précision et de reproductibilité des essais d'audition effectués par audiométrie en champ acoustique aussi élevé que possible.
Des exemples de représentations graphiques des résultats d'essai y sont donnés.
Akustika - Avdiometrijske preskusne metode - 2. del: Avdiometrija v zvočnem polju s čistimi toni in ozkopasovnimi preskusnimi signali (ISO 8253-2:2009)
Ta del ISO 8253 določa ustrezne lastnosti preskusnega signala, zahteve za prosto, difuzno in navidezno prosto zvočno polje ter postopke za avdiometrijo zvočnega polja z uporabo čistih tonov, frekvenčno moduliranih tonov ali drugih ozkopasovnih preskusnih signalov, ki jih proizvaja eden ali več zvočnikov. Glavni namen je ugotavljanje ravni slušnega praga v frekvenčnem območju med 125 Hz in 8.000 Hz, vendar se lahko razširi na območje med 20 Hz in 16.000 Hz. Ta del ISO 8253 ne vključuje specifikacij za uporabo ročnih zvočnikov. Govor kot preskusni signal ni vključen. Namen tega dela ISO 8253 je zagotoviti, da so preskusi sluha z uporabo avdiometrije z zvočnim poljem čim bolj natančni in ponovljivi. Primeri grafičnih prikazov rezultatov so podani v Dodatku A.

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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
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.
ISO 8253-2 was prepared by Technical Committee ISO/TC 43, Acoustics.
This second edition cancels and replaces the first edition (ISO 8253-2:1992), of which it constitutes a minor
revision.
ISO 8253 consists of the following parts, under the general title Acoustics — Audiometric test methods:
