The result of verbal audition depends on the speech material and the test method used. In order to ensure the use of different speech materials (including different languages Different verbal materials) For the minimum requirements of accuracy and comparability, this section sets the conditions for verbal material. It also provides Speech recognition test procedures. Acoustic audiometry method Part 3. Speech audiometry1 ScopeThis section GB/T 16296 specifies the basic method of speech recognition testing in audiological applications. In order to ensure that different test procedures (including speech recognition tests in different languages) for the minimum accuracy and comparability, this section The compilation, approval and evaluation of speech test materials and the implementation of speech recognition tests are put forward. Due to the diversity of languages, this department There is no specific regulation on the content of speech materials. In addition, this part also stipulates the establishment of the reference value, and puts forward specific requirements for the speech transmission and implementation. This section gives a detailed description of the method of audiometry, bone conduction or sound field audiometry sent by the headset, bone oscillator or speakers recorded test material And prerequisites, describe ways to use noise to mask non-test ears or as a competitive sound. This section also contains conditions for recording speech materials and recommended methods for maintaining and calibrating speech audiometry equipment. This section applies to Mandarin Speech audiometry and local dialect speech audiometry. For some subjects, such as children, a modified test method may be required and not described in this section. This section does not include some special inspection methods, such as orientation and binaural hearing method.2 Normative referencesThe following documents for the application of this document is essential.
