Many people experience an occasional ringing (or roaring, hissing, buzzing, or tinkling) in their ears. The sound usually lasts only a few minutes. Ringing in the ears that does not get better or go away is called tinnitus. You may hear a sound, such as a ringing or roaring, that does not come from your surroundings (nobody else can hear it). The sound may keep time with your heartbeat, it may keep pace with your breathing, it may be constant, or it may come and go. Tinnitus is most common in people older than age 40. Men have problems with tinnitus more often than women.
Pulsatile (like a heartbeat) tinnitus is often caused by sounds created by muscle movements near the ear, changes in the ear canal, or blood flow (vascular) problems in the face or neck. You may hear sounds such as your own pulse or the contractions of your muscles.
Nonpulsatile tinnitus is caused by problems in the nerves involved with hearing. You may hear sounds in one or both ears. Sometimes this type of tinnitus is described as coming from inside the head.
The most common cause of tinnitus is hearing loss that occurs with aging (presbycusis), but it can also be caused by living or working around loud noises (acoustic trauma). Tinnitus can occur with all types of hearing loss and may be a symptom of almost any ear disorder. Other possible causes of tinnitus include:
