ISO 389-2: 1994(E) Foreword ISO (the International Organization for Standardizationf 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. Esch 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 patt in the work. ISO collaborates closely with the International Electrotechnical Commission (1 EC) on all matters of electrotechnical standardization. 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. International Standard ISO 389-2 was prepared by Technical Committee lSO/rC 43, Acoustics. ISO 389 consists of the following Parts, under the general title Acoustics - Reference zero for the calibration of audiometric equipment: - Part 1: ßeference equivalent threshold Sound pressure levels for pure tones and supra-aural earphones - Part 2: ßeference equivalent threshold Sound pressure levels for pure tones and insert earphones - Part 3: ßeference equivalent threshold forte levels for pure tones and bone Vibrators - Part 4: Reference levels for narrow-band masking noise - Part 5: ßeference equivalent threshold Sound pressure levels for pure tones in the frequency range 8 kHz to 16 kHz - Part 6: Re ference equivalent threshold Sound pressure levels for acoustic test Signals of short duration - Part 7: Reference threshold of hearing under free-field and diffuse- field listening conditions 63 ISO 1994 All rights reserved.

ISO 389-2: 1994(E) 0 ISO Introduction Esch part of International Standard ISO 389 specifies a specific reference zero for the calibration of audiometric equipment. ISO 389:1991 (to be re-issued as ISO 389-1) contains values of reference equivalent threshold Sound pressure levels (RETSPL) for pure tones and two specified Patterns of supra-aural earphones used in conjunction with an acoustic coupler conforming to IEC 303, and for other supra-aural earphones of specified Patterns in conjunction with an artificial ear conforming to IEC 318. ISO 389-4 specifies reference Ievels for narrow-band masking noise based on these RETSPL data. In some audiological applications it may, however, be desirable to use in- sert earphones to deliver either the test Signal or the masking noise, e.g. to reduce the occlusion effect or interaural effects. RETSPL data for these kinds of earphone are specified in this part of ISO 389. lt is based on an assessment of technical data provided by laboratories in different coun- tries representing the most reliable data available at the time. lt is recognized that s
