Because the amount of people getting problems from that is tiny. At a concert of 10.000 people, I doubt more than 1 people would get permanent tinnitus or so. So why would they care?
When I was a kid they told me if you listen too loud you'll get hearing damage. At the time I thought big deal if you can't hear a few tones. But they never said anything about a phantom noise that would torment you the rest of your life.
