Hearing is elicited by applying the clinical bone vibrator to soft tissue sites on the head, neck, and thorax. Two mapping experiments were conducted in normal hearing subjects differing in body build: determination of the lowest soft tissue stimulation site at which a 60 dB SL tone at 2.0 kHz was effective in eliciting auditory sensation and assessment of actual thresholds along the midline of the head, neck, and back. In males, a lower site for hearing on the back was strongly correlated with a leaner body build. A correlation was not found in females. In both groups, thresholds on the head were lower, and they were higher on the back, with a transition along the neck. This relation between the soft tissue stimulation site and hearing sensation is likely due to the different distribution of soft tissues in various parts of the body.
通过将临床骨振动器应用于头部、颈部和胸部的软组织部位来引发听觉。在体型不同的正常听力受试者中进行了两项映射实验：确定在2.0kHz频率下60dB SL音调能有效引发听觉感受的最低软组织刺激部位，并评估沿头部、颈部和背部中线的实际阈值。在男性中，背部较低的听觉刺激部位与较瘦的体型密切相关。在女性中未发现这种相关性。在两组中，头部的阈值较低，背部的阈值较高，且在颈部有过渡。软组织刺激部位与听觉感受之间的这种关系可能是由于身体各部位软组织分布不同所致。
