This test is performed at Lafayette Hearing and Balance Center in a sound-treated room with state-of-the-art equipment. The purpose of this assessment is to determine how well a patient can hear different pitches (frequencies) as well as how well he or she can hear normal conversational speech sounds.
AUDITORY BRAIN STEM RESPONSE (ABR) TESTING
ABR testing is an evoked potential test that can be used to estimate hearing in difficult-to-test patients. it can also be used in detection, localization, and monitoring of various types of auditory nerve or auditory pathway defects.
ACOUSTIC IMMITTANCE TEST
Tympanometry – A quick and simple test that measures the status of the middle ear space and ear drum.
Acoustic Reflex Thresholds – The acoustic reflex occurs when a small muscle in the middle ear (the stapedius muscle) contracts as a results of acoustic stimulation; testing can provide information regarding middle ear function, neurological functioning of the auditory system, and an index of auditory sensitivity.
Acoustic Reflex Decay – This will test how long the stapedial reflex can be sustained; during this test, a tone is presented for 10 seconds and the muscle response is recorded; testing can provide helpful information regarding the location of a hearing problem.
