Hearing aids alone are not a cure for tinnitus, but they can help mask the ringing so that it isn’t so bothersome. Tinnitus is most commonly caused by exposure to very loud noises that irreparably damage the cells of the cochlea that are sensitive to sound. With a good pair of hearing aids, you may not notice your ear ringing at all. If you have severe tinnitus, however, you should consult an audiologist and may require a larger investment in hearing devices with advanced technology specifically to mask the ringing.
