Dr. Ronald Chin’s Take on the Hearing Tests
There are mainly 3 systems of testing for hearing loss. Tympanometry is a system of measuring the compliance of the middle ear. A pure tone signal is passed through the external auditory canal and the sound reflections are measured at different pressures, from -400 to +200mm of water. The test results are categorized as type A- normal tympanogram or SNHL, type B- restricted mobility, and type C- significant negative pressure in the ear.
Otoacoustic emissions are generally used on newborn screenings. This is used for testing hearing loss from the inner ear or the fluid in the idle ear. A series of clicks is sent to the ear and the cochlea to measure its echo.
ABR tests are for people who can’t go through usual hearing tests. In this test, electrodes are placed on your head and headphones for you to listen to certain sounds. Brainwaves of your responses to those sounds are recorded.
