Tinnitus is a ringing, buzzing, or booming in your ears. It could be caused by Meniere's disease or by an ear infection.
Tinnitus involves not only a loss of hearing, but also the addition of sounds in your head. Most commonly, tinnitus consists of a ringing in the ear. You can have tinnitus in one or both ears, and tinnitus can be temporary or permanent. Many rock musicians have tinnitus because years of being near extremely loud speakers has damaged their hearing.
