Soft tissue conduction (STC) is a recently expounded mode of auditory stimulation in which the clinical bone vibrator delivers auditory frequency vibratory stimuli to skin sites on the head, neck, and thorax. Investigation of the mechanism of STC stimulation has served as a platform for the elucidation of the mechanics of cochlear activation, in general, and to a better understanding of several perplexing auditory phenomena. This review demonstrates that it is likely that the cochlear hair cells can be directly activated at low sound intensities by the fluid pressures initiated in the cochlea; that the fetus in utero, completely enveloped in amniotic fluid, hears by STC; that a speaker hears his/her own voice by air conduction and by STC; and that pulsatile tinnitus is likely due to pulsatile turbulent blood flow producing fluid pressures that reach the cochlea through the soft tissues.
软组织传导（STC）是一种最近阐述的听觉刺激模式，其中临床骨振动器将听觉频率的振动刺激传递到头部、颈部和胸部的皮肤部位。对STC刺激机制的研究总体上为阐明耳蜗激活的力学原理提供了一个平台，并有助于更好地理解几种令人困惑的听觉现象。这篇综述表明，耳蜗毛细胞很可能在低声强下被耳蜗内产生的流体压力直接激活；子宫内完全被羊水包围的胎儿通过STC听觉；说话者通过空气传导和STC听到自己的声音；搏动性耳鸣可能是由于搏动性湍流血液产生的流体压力通过软组织到达耳蜗所致。
