Questions: Listen to or read the audio message on the left and then answer the question. How would you best describe a cochlear implant? A hearing aid that is surgically implanted behind the ear, and uses bone conduction from an external sound processor to transmit sounds to the cochlea. A form of physical therapy designed to treat a wide variety of balance disorders, including dizziness, the majority of which are caused by problems in the inner ear and vestibular nerve. Tiny ventilating tubes placed through the eardrum of a child prone to repeated ear infections to provide ongoing drainage for fluids and to relieve pressure. An electronic device that bypasses the damaged portions of the ear and directly stimulates the auditory nerve.

Solution

The answer is the last one: An electronic device that bypasses the damaged portions of the ear and directly stimulates the auditory nerve.

Explanation for each option:

A hearing aid that is surgically implanted behind the ear, and uses bone conduction from an external sound processor to transmit sounds to the cochlea.
- This describes a bone-anchored hearing aid (BAHA), not a cochlear implant. A BAHA uses bone conduction to transmit sound vibrations directly to the inner ear.
A form of physical therapy designed to treat a wide variety of balance disorders, including dizziness, the majority of which are caused by problems in the inner ear and vestibular nerve.
- This describes vestibular rehabilitation therapy (VRT), which is unrelated to cochlear implants.
Tiny ventilating tubes placed through the eardrum of a child prone to repeated ear infections to provide ongoing drainage for fluids and to relieve pressure.
- This describes tympanostomy tubes, also known as ear tubes, which are used to treat chronic ear infections, not to aid in hearing.
An electronic device that bypasses the damaged portions of the ear and directly stimulates the auditory nerve.
- This correctly describes a cochlear implant. Cochlear implants are used to provide a sense of sound to individuals who are profoundly deaf or severely hard of hearing by directly stimulating the auditory nerve.
