AABR Screening

ABR activity is a direct measurement of the neural response to sound that is generated along the auditory system from the level of the cochlea and through the VIII nerve and pontine level of the brainstem and that correlates with behavioral hearing measures in the mid-to high-frequency region. The ABR is recorded using surface electrodes that are attached to the infant's head. Click stimuli are presented through insert or muff-style earphones that are worn on both ears. ABR measurements are sensitive to neural auditory disorders (i.e., auditory neuropathy).
