Proposes the adoption of IEC 373:1990, Mechanical coupler for measurements on bone vibrators as a Joint Australian/New Zealand Standard. This proposed Standard specifies requirements for mechanical couplers used for calibrating bone-conduction audiometers and for making measurements on bone vibrators and bone conduction hearing aids in the frequency range from 125 Hz to 8000 Hz inclusive. It differs from AS 1591.4 in the construction of the mechanical coupler and in that the frequency range has been widened. Copies of IEC 373:1990 may be purchased from or viewed at any Standards Australia office.
