This defect in normal cochlear function, specifically, in the transduction of a mechanical acoustic signal into auditory nerve synaptic activity, represents a broken link in the delicate chain that constitutes the human sense of hearing. Cochlear implants afford an artificial means to bypass this disrupted link via direct electric stimulation of auditory nerve fibers.
