Tinnitus – sound without an external source

In brief

Tinnitus means hearing sounds such as ringing, hissing or buzzing without an outside source. Experiences differ widely.

What it can mean in daily life

It can be related to hearing loss or noise exposure, but other causes are possible. Many people notice it more in quiet surroundings.

Next steps

Seek healthcare advice if tinnitus troubles you, is new or comes with a change in hearing. For sudden hearing loss in one ear, Swedish service 1177 advises contacting a healthcare centre or out-of-hours clinic as soon as possible.
