If you've ever had a ringing in your ears after a loud concert or being around other loud noise, you may have experienced tinnitus. Tinnitus is the perception of sound when there is no external source of the noise. It can be intermittent or constant, and it can vary in pitch from a low roar to a high squeal. While most people experience tinnitus for only a short time, some people develop chronic tinnitus that lasts for years.
There are two types of tinnitus: objective and subjective. Objective tinnitus can be heard by an examiner using special instruments placed next to the ear. Subjective tinnitus can only be heard by the person experiencing it. Most cases of tinnitus are subjective.
Tinnitus is often caused by exposure to loud noise. It can also be caused by certain medications, head or neck injuries, jaw misalignment, and thyroid problems. In many cases, the exact cause of tinnitus cannot be determined.
There is no cure for tinnitus, but there are treatments that can help lessen its effects. If your tinnitus is due to exposure to loud noise, avoiding further exposure to loud noise is important.
