Tinnitus or ringing in the ears, is the sensation of hearing ringing. The noise can be intermittent or continuous, and can vary in loudness. It is often worse when background noise is low, so you may be most aware of it at night when you’re trying to fall asleep in a quiet room

There are two kinds of tinnitus.

  • Subjective tinnitus is tinnitus only you can hear. This is the most common type of tinnitus. It can be caused by ear problems in your outer, middle or inner ear. It can also be caused by problems with the hearing (auditory) nerves or the part of your brain that interprets nerve signals as sound (auditory pathways).
  • Objective tinnitus is tinnitus your doctor can hear when he or she does an examination. This rare type of tinnitus may be caused by a blood vessel problem, a middle ear bone condition or muscle contractions.

Symptoms:

Tinnitus symptoms may include these types of phantom noises in your ears:

  • Ringing
  • Buzzing
  • Roaring
  • Clicking
  • Hissing
  • Humming

The phantom noise may vary in pitch from a low roar to a high squeal, and you may hear it in one or both ears. In some cases, the sound can be so loud it can interfere with your ability to concentrate or hear external sound. Tinnitus may be present all the time, or it may come and go.

Causes:

Tinnitus is not a disease but a symptom that can result from a number of underlying causes. A common cause of tinnitus is inner ear hair cell damage. Tiny, delicate hairs in your inner ear move in relation to the pressure of sound waves. This triggers cells to release an electrical signal through a nerve from your ear (auditory nerve) to your brain. Your brain interprets these signals as sound. If the hairs inside your inner ear are bent or broken, they can “leak” random electrical impulses to your brain, causing tinnitus. In many cases, an exact cause is never found.

Other causes of tinnitus include

  • Age-related hearing loss
  • Noise-induced hearing loss. (or) Exposure to loud noise
  • Ear infections,
  • Ear wax blockage
  • Meniere’s disease,
  • Otosclerosis
  • Emotional stress,
