Comprehensive Hearing Exams and Screenings
Centerville Hearing Center offers Comprehensive Hearing Exams and Screenings in Centerville, Dayton and surrounding cities in Montgomery County, OH.
The softest sounds you hear at each pitch make up your hearing threshold and those thresholds are marked on your audiogram. Typically, the parts of the test given to you through headphones are called 'air' thresholds because the sound must travel through the air of the ear canal to be heard. An O is used for the right ear and an X is used for the left ear to represent your air thresholds.
A bone-conduction vibrator is usually used to test for thresholds as well. A < symbol is used for the right ear and a > symbol is used for the left ear. A bone-conduction vibrator is a device that gently rests on the bone behind the ear and is held in place by a small metal band stretching over the top of the head. This device transmits sound vibrations through the bones and tissue and fluids within the skull directly to the cochlea (the hearing organ of the inner ear). This process allows the examiner to bypass your outside and middle ear areas and test the sensitivity of your inner ear directly.
