With tinnitus, for reasons not fully understood, the nerve transmits impulses that originate inside the head or within the ear itself. Avoid the risk factors where possible. Your own observation of symptoms. Medical history and physical exam by a doctor. Psychological problems may develop due to feelings of distress for those who find the noise intolerable.
Some people tolerate the condition much better than others.
Try to ignore the sound by directing your attention to other things and activities. Play music in the background during the day and while falling asleep. Get help with a cessation program if you need it. A hearing aid for any associated deafness may help mask tinnitus. Wear a tinnitus suppressor or masker, a device that fits in the ear like a hearing aid and presents a more pleasant sound.
