- Scope
- The following contents stipulated in this standard are applicable to the calibration of bone oscillators for pure tone bone conduction audiometry. a) Baseline equivalent threshold force level, which is equivalent to the hearing threshold of bone conduction audiometry of normal young people in otology. Note 1: The tentative difference of the baseline equivalent threshold level between the forehead and the mastoid is listed in Appendix C. b) The basic characteristics of the bone vibrator and its coupling method with the subject and with the mechanical coupler. c) Basic characteristics and baseline levels of masking noise applied to the non-test ear. Guidelines for the practical use of this standard in calibrating audiometers are listed in Appendix A. Note 2: The standard method for bone conduction audiometry has been specified in GB/T 16403-1996.
