What can cause tinnitus?

  • Ear infection on the middle ear bones or on the ear drum can tinnitus causes.
  • Tinnitus is also a sign of old age, as many sufferers are the elderly. Theories suggest that as we age, the cochlea, part of the ear that allows us to hear, no longer sends normal signals to the brain. The brain in turn produces its own noise to make up for the lack of stimuli from sound signals.
  • Exposure to continuous loud noises can cause ringing in the ear and may also lead to loss of hearing. Tinnitus may be a result of the occupational hazard of being exposed to noisy machines.
  • Some medication such as aspirin and strong anti-biotic medication when taken excessively can make an adverse effect on your ear and cause tinnitus.

  • Somatic tinnitus is caused by something that is outside of the inner ear. People with head and neck injuries also suffer from tinnitus. People who suffer from Temporomandibular joint arthritis usually experience severe tinnitus. Furthermore, jaw-joint misalignment may also be a cause somatic tinnitus.
  • Tinnitus may occur as a sleep disorder where one hears a tremendously loud noise while falling asleep or waking up. The theory is that is that it is caused by a quick seizure in the auditory cortex.
