Programs that establish the nature and extent of an individual's hearing loss in order to devise an appropriate treatment plan. Evaluations may include pure tone and speech audiometry which measure hearing in terms of reception of calibrated test tones or spoken words which are presented at controlled levels of intensity; impedence tests which measure the integrity of the middle ear system and rule out conductive pathology; and auditory brain stem tests which utilize equipment similar to an EKG to measure neurological activity in response to auditory stimuli.
