This standard specifies the requirements for test signal characteristics, free field, diffuse sound field and quasi-free field; the steps of sound field audiometry with pure tone, FM tone or other narrow-band noise test signals provided by one or more loudspeakers, mainly The purpose is to determine the hearing threshold level in the frequency range of 125-12500 Hz. This standard does not include technical requirements for the use of hand-held loudspeakers. This standard does not cover the use of speech as a test signal. The purpose of this standard is to ensure that hearing tests performed by sound field audiometry give the highest possible accuracy and reproducibility. Appendix A (prompted appendix) gives examples of graphic results and Appendix C (prompt appendix) gives references.
