Hair Cells & Tnnitus

Scientists believe when hair cells are damaged the brain compensates by generating the perception of a buzzing or ringing in the ears know as tinnitus. Like a radio station out of range, the brain tries harder to pick up a signal and the result is only loud static. The phantom auditory sensation is like a missing arm or leg. We still can experience pain in even in a limb that has been amputated. Other causes of tinnitus include head and neck trauma, advancing age, certain types of tumors, wax buildup and some medications including certain antibiotics, according to the American Tinnitus Association. More than 50 million Americans experience some degree of tinnitus.
