Hi All -
In another thread @Mpt wrote about his mom, a teacher who had tinnitus but was unaware of it until another teacher missed a few days of school because of her own tinnitus. You can read the details here:

Anyway, that got me thinking. Back in 1953 Heller and Bergman did an interesting experiment that has since been duplicated a couple of times. They took eighty healthy adults with normal hearing and no history of tinnitus. They put them one by one in an audiogram booth with the same instructions every one of us is familiar with: when you hear the sound I put into your headphones, push the button. And very shortly 94% of them pushed the button. But nobody ever introduced a sound into their headphones! What these folks heard upon purposely listening hard for sound in a silent environment was their own tinnitus that they never before knew they had. You might think it was their imagination, but when asked to describe the sound they heard through their headphones, the variety of descriptions - hum, ring, buzz, crickets, hiss, roar, etc. - was the same as folks who have severe intrusive tinnitus describe.
So some degree of tinnitus - even tinnitus that is so innocuous that people are totally unaware of it unless straining to hear it in a silent room - is a normal physiological phenomenon. (Makes sense, when you think of it, because the auditory system is one of the most active systems in the body.) Now obviously folks on this board do not have just a little tinnitus; they have a lot of tinnitus. But let's suppose you are a researcher searching for a cure for tinnitus. How do you cure something the mere presence of which is normal? Do you just cure tinnitus of a certain loudness? And if that's the case, how loud is loud? Isn't it sort of a moving target?
I do not have any answers here. Just something to think about.
