21、 Scope This report applies to the performance characteristics of hearing aids. Measuring methods that take into account the acoustical influence of the wearer on the performance of hearing aids are important, particularly when the results are to be used to assist in the fitting of hearing aids. The
22、information obtained using this report is likely to be more relevant to the fitting of hearing aids than that provided by publications concerned with type approval and quality control such as IEC Publication 118-0: Hearing Aids: Part 0: Measurement of Electroacoustical Characteristics, and IEC Publi
23、cation 118-7: Hearing Aids, Part 7: Measurement of Performance Characteristics of Hearing Aids for Quality Inspection for Delivery Purposes. The methods specified in this report require a device such as a manikin to simulate the presence of the wearer. Work on a report for a head and torso simulator
24、 is in progress. Pending an agreement on a manikin, it has been found necessary to establish certain guidelines for simulated in situ measurements of hearing aids. The recommended methods are described in this report. 2 Object The purpose of this report is to describe test methods which simulate the
