There's still the risk of inducing tinnitus (esp. if you had some mild hearing damage already, which I'm guessing is pretty common) - the theory is that, in total silence, the brain can eventually notice even the faintest tinnitus sound (that you might have had already due to hearing damage, but didn't notice because it was so quiet), and once you've became conscious of it, it will never go away.
