Well, I agree, but I think that horse has bolted long ago. The article discusses the risk of extended loud listening with headphones, which employees buy themselves (I've never heard of an employer buying headphones).
My point was that as long as you're buying headphones anyway, buy some good noise-cancelling ones, and you'll mitigate a lot of the risks in the article. It does suck that it's on employees to do this, but here we are.
You're right. However, in most cases a lowly worker bee in an office environment doesn't really have too many options. Several years ago I was in a really bad office noise situation and I went out and bought Bose QC-15 headphones for $300. It was the best $300 I ever spent. I still have them and I still regularly use them in my home office. When they break, I plan to buy another pair.
