标准范围

规定了适用于校准纯音骨传导测听用骨振子的以下数据:参考等效阈值力水平（RETFL），对应于通过骨传导测测听的年轻听力正常人的听力阈值；骨振子的基本特征及其与受试者和机械耦合器耦合的方法；应用于未测试耳朵的掩蔽噪声的基本特征和基准水平。

Specifies the following data applicable to the calibration of bone vibrators for pure-tone bone-conduction audiometry: reference equivalent threshold force levels (RETFL), corresponding to the threshold of hearing of young otologically normal persons by bone-conduction audiometry; essential characteristics of the bone vibrator and of its method of coupling to a person under test and to the mechanical coupler; essential characteristics and datum level of the masking noise applied to the ear not under test.
