how hearing works


Tinnitus is a constant ringing, hissing, or roaring sound in one or both ears. The American Tinnitus Association reports as many as 50 million Americans suffer from tinnitus, with 90% of that population having some level of noise-induced hearing loss.

Although the causes of tinnitus are unknown, hearing care professionals link the condition to many potential causes in the inner ear, outer ear, and from effects of trauma, disorders, and certain medications.

Due to its unknown origin, tinnitus does not yet have a cure. However, there are ways to manage tinnitus in order to continue enjoying daily activities:

  • Using hearing aids to mask the sounds of tinnitus
  • Eating a healthy diet
  • Being physically and socially active
  • Behavioral, drug, or experimental therapies
