Soft tissue conduction (STC) is a recently described mode of auditory stimulation in which vibrations induced by a clinical bone vibrator applied to soft tissue sites on the head, neck, and thorax of human subjects reach the cochlea and elicit auditory sensation. In humans, STC stimulation interacts with air conduction stimulation and with bone conduction (BC) stimulation in several ways, e.g., mutual masking.
This study investigated whether mutual masking between STC and BC stimulation can be demonstrated in an experimental animal. In fat sand rats, auditory nerve and brainstem evoked response to BC stimulation was recorded in the presence of noise masking presented by STC and vice versa.
STC successfully masked BC, and BC also masked STC responses.
Mutual masking, now demonstrated in animals, paves the way for animal experiments to clarify the pathway between the STC stimulation sites and the cochlea.
软组织传导（STC）是一种最近被描述的听觉刺激模式，其中应用于人类受试者头部、颈部和胸部软组织部位的临床骨振动器所诱发的振动到达耳蜗并引发听觉感受。在人类中，STC刺激以多种方式与气导刺激和骨传导（BC）刺激相互作用，例如相互掩蔽。
本研究调查了在实验动物中是否能证明STC和BC刺激之间的相互掩蔽。在肥沙鼠中，在存在由STC呈现的噪声掩蔽的情况下记录对BC刺激的听神经和脑干诱发反应，反之亦然。
STC成功掩蔽了BC，BC也掩蔽了STC反应。
现在在动物中证明的相互掩蔽为动物实验铺平了道路，以阐明STC刺激部位与耳蜗之间的通路。
