The U.S. Centers for Disease Control estimates that nearly 15% of the general public — over 50 million Americans — experience some form of tinnitus. Roughly 20 million people struggle with burdensome chronic tinnitus, while 2 million have extreme and debilitating cases.
That's from
the ATA's site.
If my math is correct, then among T sufferers:
- 4% haven't habituated at all and have a debilitating/disabling form of T
- 40% have "burdensome T" - whatever that means, but it doesn't sound like it means they habituated well
- the rest must be living with it without too much of a burden (which may fit well into the "habituated" bucket)
It doesn't look like a vast majority habituates. A small majority yes, but not large enough to dwarf the other guys.
