Several types of hearing tests can be administered to cancer patients. These include: - Audiometry: Measures the ability to hear sounds at different pitches and volumes. - Otoacoustic Emissions (OAEs): Evaluates the function of the outer hair cells in the cochlea. - Auditory Brainstem Response (ABR): Assesses the neural pathways for hearing. - Tympanometry: Tests the condition of the middle ear and mobility of the eardrum.
