This standard specifies the methods and necessary conditions for air conduction, bone conduction or sound field speech audiometry by sending recorded examination materials through earphones, bone vibrators or loudspeakers, and describes the use of noise to mask non-test ears or as competing sounds. method. This standard also covers the conditions for recording language material and recommended methods for maintaining and calibrating language audiometry equipment. This standard applies to the language audiometry of Mandarin Chinese and local dialects. For some objects to be examined, such as children, it may be necessary to adopt modified examination methods, which are not described in this standard. This standard does not apply to the live ovice language test method. In the suggestive appendix, several suggestions are made to help make the speaking test as reliable as possible. Due to the diversity of languages, this standard does not specify the content of language materials. Different types of test materials can have a significant impact on language audiometry results. This standard does not include some special inspection methods, for example, orientation and binaural dichotomy inspection method, etc.
