Par
11、t 7: Measurement of the performance characteristics of hearing aids for quality inspection for delivery purposes” published by the International Electrotechnical Commission (IEC). This standard is also in agreement with Harmonization Document HD 450.7 S1 published by the European Committee for Elect
12、rotechnical Standardization (CENELEC). In 1993 the European Committee for Electrotechnical Standardization (CENELEC) accepted IEC 118-7:1983 as European Standard EN 60118-7:1993. As a consequence of implementing the European Standard this British Standard is renumbered as BS EN 60118-7 and any refer
13、ence to BS 6083-7 should be read as a reference to BS EN 60118-7. BS 6083 consists of the following Parts: Part 0:1984: Methods for measurement of electroacoustical characteristics; Part 1:1984: Methods for measurement of characteristics of hearing aids with induction pick-up coil input; Part 2:1984
14、: Methods for measurement of electroacoustical characteristics of hearing aids with automatic gain control circuits; Part 3:1991: Methods for measurement of electroacoustical characteristics of hearing aid equipment not entirely worn on the listener; Part 4:1981: Specification for magnetic field str
