Acoustics - Audiometric test methods - Part 1: Basic pure tone air and bone conduction threshold audiometry (ISO 8253-1:1989)

Specifies procedures and requirements. For screening purposes only air conduction pure tone audiometric test procedures are described. Procedures and requirements for speech audiometry, electrophysiological audiometry, and where loudspeakers are used as a sound source are not specified.

Akustik - Audiometrische Prüfverfahren - Teil 1: Grundlegende Verfahren der Luft- und Knochenleitungs-Schwellenaudiometrie mit reinen Tönen (ISO 8253-1:1989)

Dieser Teil von ISO 8253 legt Verfahren und Anforderungen für Luft- und Knochenleitungs-Schwellenaudiometrie fest. Für Screening-Untersuchungen werden nur Reinton-Luftleitungs-Verfahren beschrieben. Die Verfahren sind möglicherweise für besondere Gruppen, z.B. sehr junge Kinder, nicht geeignet.

1s0 8253-l : 1989 (El Foreword IS0 (the International Organization for Standardization) is a worldwide federation of national standards bodies (IS0 member bodies). The work of preparing International Standards is normally carried out through IS0 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, govern- mental and non-governmental, in liaison with ISO, also take part in the work. IS0 collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. Draft International Standards adopted by the technical committees are circulated to the member bodies for approval before their acceptance as International Standards by the IS0 Council. They are approved in accordance with IS0 procedures requiring at least 75 % approval by the member bodies voting. International Standard IS0 8253-l was prepared by Technical Committee ISO/TC 43, Acoustics. IS0 8253 will consist of the following parts, under the general title Acoustics - Audio- metric test methods: - - Part I: Basic pure tone air and bone conduction threshold audiometry Part 2: Sound field audiometry with pure tone and narrow-band signals Annex A of this part of IS0 8253 is for information only. 0 IS0 1989 All rights reserved.

ISO8253-1 :1989 E) Introduction This International Standard lays down requirements and procedures for carrying out basic audiometric tests in which pure tones are presented to the test subject using earphones or bone vibrators. Electrophysiological test methods are not included. Pro- cedures for air conduction threshold audiometry for hearing conservation purposes are given in IS0 6189. Where appropriate, both International Standards have been brought into line with one another. In order to obtain a reliable measure of hearing ability, many factors are involved. IEC 645 specifies requirements for audiometers. It is essential that audiometric equip- ment, when in service, be checked and the calibration maintained. This part of IS0 8253 outlines a calibration scheme. To avoid masking of the test signal by ambient noise in the audiometric test room, the levels of the ambient noise shall not exceed cer- tain values, depending upon the method of signal presentation to the test subject, i.e. by earphone or by bone vibrator. This part of IS0 8253 gives maximum permissible ambient sound pressure levels which shall not be exceeded when hearing threshold levels down to 0 dB have to be measured. It indicates the maximum ambient sound pressure levels which are permissible when other minimum hearing threshold levels have to be measured. It sets out procedures for determining hearing threshold levels by pure tone air conduction and bone conduction audiometry. For screening purposes, only methods for air conduction audiometry are outlined. Audiometry can be performed by using a) a manual audiometer; b) an automatic recording audiometer; c) computer-controlled audiometric equipment. Methods for threshold audiometry are given for these three types of signal presenta- tion. For screening purposes, only methods using a manual or a computer controlled audiometer are set out.
