  4. Otoacoustic Emissions (OAEs) :

    A small microphone is placed in the ear canal to measure sound waves produced by the inner ear in response to auditory stimuli. This test assesses the function of the inner ear (cochlea).

  5. Auditory Brainstem Response (ABR) :

    Electrodes are placed on the scalp to measure brain responses to sound clicks.ABR evaluates the auditory pathway from the ear to the brain.
