Our expert says:
There are several methods of helping a patient manage tinnnitus. Your audiologist was referring to the fact that when the brain is deprived of sound due to a hearing loss even at just a few frequencies, it may "increase its gain" to try to compensate for what it is not getting, and instead detects tinnitus. Hearing aids are often very helpful for tinnitus patients becasue it gives the brain some of the stimulation it is lacking from the ear. I suspect that your audiologist felt that some of the hair cells (not really hairs) were damaged. If they are only damaged at a few frequencies you may not even be aware of any hearing problem (but your brain might be). Hearing your heartbeat might be related to high blood pressure or a vascular issue. Therefore, you should consult with your medical physician to get this checked out.
