The 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 Publication 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 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.【中国标准分类号】: L31【国际标准分类号】: 11_180_15【页数】: 72P.;A4【正文语种】: 英语
