标准摘要
[中文适用范围]： IEC 60318的这一部分描述了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。该耦合器用于使用平面圆形尖端面积为 175 mm² ± 25 mm² 的骨振动器校准听力计，并用于确定骨传导助听器的性能。一般来说，骨振动器产生的振动力在耦合器上与在人的乳突上不同。然而，IEC 建议将其用作校准听力测定中使用的指定振动器以及交换骨导助听器规格和数据的手段。注：一些助听器的骨振动器和一些仍在测听中使用的非标准化骨振动器具有弯曲的表面。用户应注意，这些振动器一般不会加载在与本标准表1规定的机械阻抗相同的机械耦合器上。 [外文原描述]： 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.
