The author of the article with a link in a previous post stated "Tinnitus is a neurological problem that originates in the brain, involving miscommunication between noise-damaged sensory cells; the result is a continuous ringing sound in the ears. Tinnitus is permanent. Once sensitive hair cells are damaged, they can no longer transmit impulses to the auditory nerve and to the brain. 50 million Americans suffer from tinnitus (2 million become so debilitated by unrelenting ringing that they are incapable of carrying out normal daily activities), and musicians are at significantly higher risk than the general population. The only other group who suffer so ubiquitous from hearing damage are GIs exposed to wartime explosions."
The takeaway here (of real significance) is that he says it is permanent. I must assume that this is what distinguishes real "T" from a temporary ringing caused by excessive noise exposure. I have read throughout this forum of people stating that their "T" came and went?
It is good to hear the positive stories as in this thread about famous people with "T" that went on to live fulfilling lives.
