I've taken aspirin and Vitamin E daily for years now and I still have more crickets than a John Wayne movie chirping no stop in my head 24/7. I wear ear plugs when ever I shoot and work around equipment too.
I've had hearing loss since I was a kid, back when hearing protection was some cotton or empty shell cases stuffed in your ears, if you used anything at all. I'm still loosing it as I age though. To many years of rapid sharp noises, or continual droning.

of what use was the rule?"
