IEC 60118-16:20 22给出了常见助听器特性的定义，如降噪或减少反馈等。仅考虑声学输入。本文档目前未涵盖双耳功能。此外，描述了用于验证助听器特征的测量过程。目标不是评估特性的性能，而是验证它们的存在和功能。 此外，定义和程序尽可能通用，使得本文件可以应用于各种类型的助听器，例如空气传导助听器或骨传导助听器。为此，采用IEC 60118-0中给出的术语“助听器”的一般定义，并且该文件不涉及任何特定的耳朵模拟器或声学耦合器，而是使用耦合器的一般定义。然而，如果一般观点不适用或导致不清楚或复杂的措辞，则仅考虑空气传导助听器的情况。然而，给出了如何将本文件应用于不使用空气传导的助听器的解释。

IEC 60118-16:2022 gives definitions for common hearing aid features such as noise reduction or feedback reduction, etc. Only acoustical inputs are considered. Binaural features are currently not covered in this document. In addition, measurement procedures are described to verify hearing aid features. The objective is not to evaluate the performance of features but to verify their existence and functionality.
Furthermore, definitions and procedures are kept as general as possible so that this document can be applied to various types of hearing aids, for example, air-conduction hearing aids or bone conduction hearing aids. To this end, the general definition for the term "hearing aid" given in IEC 60118-0 is adopted, and this document does not refer to any specific ear simulator or acoustic coupler but uses a general definition of a coupler. However, if a general view is not applicable or leads to unclear or complex wording, the situation for an air-conduction hearing aid only is considered. Nevertheless, an explanation is given on how this document can be applied to hearing aids which do not use air conduction.
