--- Revised 12.1 overview part of the relevant content (see 12.1.1);

--- Added fixed step adaptation and other adaptive methods (see 12.4 and 12.5);

--- Modify the speech recognition accompanied by competitive sounds to speech audiometry accompanied by competitive speech (see Chapter 15, Chapter 15 of the 1999 edition);

--- Added 15.4 general clause (see 15.4.1);

--- Increased measurement uncertainty (see Chapter 17);

--- Removed information appendix oral examination (see the 1999 edition of Appendix A);

--- Added informative appendices Examples of speech materials, examples of competitive sounds, typical results, optimization of the perceived balance of the test table, measurement uncertainty (See Appendix A, Appendix B, Appendix C, Appendix D and Appendix E);

--- The.1999 edition of Appendix B was revised as a reference, and added four articles with Chinese speech audiometry literature (see 1999 edition of Appendix B, references).

This section uses the translation method identical with ISO 8253-3:2012 "Acoustics listening method Part 3. Speech audiometry." the documents of our country that are consistent with the corresponding international documents that are normative references in this section are as follows.

Introduction

Speech audiometry is used for hearing tests related to diagnostic assessment and hearing rehabilitation.

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 audiometry

1 Scope

This 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.
