标准简介
Proposes the adoption of ISO 7566:1987, Acoustics - Standard reference zero for the calibration of pure-tone bone conduction audiometers as a Joint Australian/New Zealand Standard. This proposed Standard specifies reference equivalent threshold force levels, essential characteristics of the bone vibrator and levels of masking noise applied to the ear not under test. These are applicable to the calibration of bone vibrators for pure-tone bone conduction audiometry. Copies of ISO 7566:1987 may be purchased from or viewed at any Standards Australia office.
