Final answer:
Electrocochleography is the measurement of the electrical activity of the cochlea. It is used to evaluate hearing function and assess hearing disorders and cochlear implants.
Step-by-step explanation:
Electrocochleography is the measurement of the electrical activity of the cochlea, which is the part of the inner ear responsible for hearing. It is a diagnostic tool used to evaluate the function of the cochlea and is often used in the assessment of hearing disorders and cochlear implants. By placing electrodes on the skin near the ear, the electrical signals produced by the cochlea can be recorded and analyzed.
