One in ten people suffer from Tinnitus. It causes a ringing or noise in the ears which, for some people, is permanent. There's no cure but you can get help to learn to live with it.

Malcolm Shaw reports and speaks to Tinnitus sufferer Sheree Wall, Natalie West and Ali Adolph from Brighton Flash Dance Mobs, Jane Bailey from Action on Hearing Loss and Nick Sellors, a victim of hearing loss.
