- Scope
- This part of GB/T 16296 specifies the requirements for free sound field, diffuse sound field, quasi-free sound field and the characteristics of related test signals, as well as the use of pure tone, FM tone and other narrow-band noise test signals provided by one or more loudspeakers for sound field testing. method of listening. This section applies to the determination of hearing threshold levels in the frequency range of 125 Hz to 8 000 Hz, but this frequency range can be extended to 20 Hz to 16 000 Hz. This standard does not include requirements for the use of hand-held loudspeakers, nor does it include the use of speech as a test signal. The purpose of this standard is to conduct hearing tests using sound field audiometry to ensure the highest possible accuracy and reproducibility. Appendix A gives sample graphs of audiometry results.
