Researchers claim that ringing in your ears, also called tinnitus, is caused by the lack of sound due to gradual hearing loss. This hearing loss can be caused by various factors, among them normal aging, loud-noise exposure, or an accident. The brain therefore is inclined to produce its own sounds to replace the frequencies that are missing in what the ear hears. Tinnitus is the result when the brain’s limbic system (the part of the brain that deals with basic instincts and emotions) fails to keep this sounds from being processed by the auditory system! Around 40 million Americans currently suffer from this chronic annoyance, for which there is no known cure.
