Ask Slashdot: Best Way To Block Noise In a Dorm?

First time accepted submitter zmitch32 writes "I live in a dorm, and I have ADHD, so every little noise distracts me. I know this annoyance isn't limited to those with ADHD, so how does everyone else block out the noise? I can't really cover my walls in soundproof foam because I live in a dorm. I can't just listen to music because I find it too interesting and just end up getting distracted by it. I use ear plugs to block out small noises, but they don't block out human voices very well at all. What do you guys/gals recommend?"
