A piesoelectric bony telephone for determining audible thresholds while sound is conducted through the bone over expanded frequency range of 0.25 kHz up to 20.0 kHz is described. Fundamental limitations of electromagnetic bony telephones preventing them from metering audible thresholds at the frequencies greater than 6 kHz have been revealed. Analysis of the piesoelectric transducer equivalent circuit has demonstrated on principle the possibility to measure audible thresholds with such a device over the expanded frequency range to 20 kHz. A model of piesoelectric bony telephone conforming the IEC recommendations is described and some experimental results obtained for the frequency range of 0.25 kHz to 20.0 kHz are presented.
描述了一种用于在0.25 kHz至20.0 kHz的扩展频率范围内通过骨骼传导声音时确定听觉阈值的压电骨传导电话。揭示了电磁骨传导电话在频率大于6 kHz时无法测量听觉阈值的基本局限性。对压电换能器等效电路的分析原则上证明了使用这种设备在扩展频率范围至20 kHz内测量听觉阈值的可能性。描述了符合IEC建议的压电骨传导电话模型，并给出了在0.25 kHz至20.0 kHz频率范围内获得的一些实验结果。
