What causes tinnitus?

Tinnitus is of sound inside the ear or head when no external sound is present. It is often referred to as ”ringing in the ears,” although some people hear buzzing, hissing, whistling, roaring, pulsating, chirping, or clicking. Tinnitus can be intermittent or constant, with single or multiple tones. Its’ perceived volume can range from very soft to extremely loud.

The exact cause of tinnitus is not known in most cases. There are, however, several likely factors which may cause tinnitus or make existing tinnitus worse like noise-induced hearing loss, wax build-up in the ear canal, certain medications, ear or sinus infections, age-related hearing loss, ear diseases and disorders, jaw misalignment, cardiovascular disease, certain types of tumours, thyroid disorders, head and neck trauma and many others. Of these factors, exposure to loud noises and hearing loss are the most probable causes of tinnitus.
