Tinnitus, commonly described as ringing in the ears or head, is experienced by as many as 22 million Americans—nearly 10% of the adult population. The ringing can be steady or intermittent, in one ear or both. While usually reported as a ringing or whistling, it may be a buzzing, humming or roaring sound. Tinnitus is a symptom, not a disease. It can have many causes including: noise exposure, earwax blockage or a reaction to medication or the natural aging process. It is estimated that 90% of tinnitus sufferers have some degree of hearing loss. People with tinnitus can sometimes think the tinnitus causes them to have trouble hearing when, in fact, the hearing loss may be causing the tinnitus. Damage to the hair cells in the inner ear is a common source of tinnitus. Hearing aids are helpful to many people bothered by tinnitus. Our advanced hearing aids include tinnitus masking features as well. The better you hear, the less you notice your tinnitus.
