介绍一种用于测量骨振动器输出力的机械耦合器。耦合器的机械阻抗规定在125 Hz至8 000 Hz的频率范围内。该耦合器用于使用骨振子校准听力计，骨振子的平面圆形尖端面积为175 mm2±25 mm2，并用于测定骨传导助听器的性能。 骨振动器产生的振动力通常与人的乳突上的振动力不同。 然而，IEC建议将其用作校准测听中使用的特定振动器以及交换骨传导助听器规范和数据的手段。 本标准取消并取代1990年发布的IEC 60373。第一版为技术修订版。

Describes a mechanical coupler for the measurement of the output force of bone vibrators. The mechanical impedance of the coupler is specified in the frequency range 125 Hz to 8 000 Hz. The coupler is intended for calibration of audiometers using bone vibrators having a plane circular tip area of 175 mm2 ± 25 mm2 and for determining the performance of bone conduction hearing aids. The vibratory force developed by a bone vibrator is not, in general, the same on the coupler as on a person's mastoid. However, the IEC recommends its use as a means for the calibration of specified vibrators used in audiometry and for the exchange of specifications and of data on bone conduction hearing aids. This standard cancels and replaces IEC 60373 published in 1990. This first edition constitutes a technical revision.
