10、I 10-1999 National foreword This Part of BS 6083 has been prepared under the direction of the Electronic Equipment Standards Committee and is identical with IEC Publication 118-9:1985 “Hearing aids Part 9: Methods of measurement of characteristics of hearing aids with bone vibrator output”, publishe
11、d by the International Electrotechnical Commission (IEC). This standard is also in agreement with Harmonization Document HD 450.9 S1 published by the European Committee for Electrotechnical Standardization (CENELEC). BS 6083 consists of the following Parts: Part 0:1984: Methods for measurement of el
12、ectroacoustical characteristics; Part 1:1984: Method for measurement of characteristics of hearing aids with induction pick-up coil input; Part 2:1984: Methods for measurement of electroacoustical characteristics of hearing aids with automatic gain control circuits; Part 3:1984: Methods for measurem
13、ent of electroacoustical characteristics of hearing aid equipment not entirely worn on the listener; Part 4:1981: Specification for magnetic field strength in audio-frequency induction loops for hearing aid purposes; Part 5:1984: Specification for dimensions of the nipple and sealing device for inse

15、ics of hearing aids under simulated in situ working conditions; Part 9:1986: Methods for measurement of characteristics of hearing aids with bone vibrator outputs; Part 10: Guide to hearing aid standards; Part 11:1984: Specification for symbols and other markings on hearing aids and related equipmen
16、t. Terminology and conventions. The text of the International Standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards. Textual error. When adopting the text of the
17、International Standard, the textual error given below was discovered. It has been marked in the text and has been reported to the IEC in a proposal to amend the text of the International Standard. In the introduction, in line 2 of paragraph 5, for “(e.g. a headband type bone conduction hearing aid)”
18、 read “(e.g. a spectacle type bone conduction hearing aid)”.
