At Niagara Hearing & Speech Clinic we offer professional services for hearing tests and hearing aids & audiology! Audiometry is the testing of a person's ability to hear various sound frequencies. The test is performed with the use of electronic equipment called an audiometer. This testing is usually administered by a qualified hearing care professional, either an Audiologist or a Hearing Instrument Specialist. Please call to set up a time with Scott C Jackson today!
