Figure 36.14 Cochlear implants can restore hearing in people who have a nonfunctional cochlea The implant consists of a microphone that picks up sound.

Which of the following types of hearing loss would not be restored by a cochlear implant? Hearing loss resulting from absence or loss of hair cells in the organ of Corti. Hearing loss resulting from an abnormal auditory nerve. Hearing loss resulting from fracture of the cochlea. Hearing loss resulting from damage to bones of the middle ear.
