Earplugs and brown noise. I can just, if I concentrate, make out _that there are people talking_. But since I completely can't parse it, it doesn't disturb me. The earplugs mean that I can listen to it at a much greater volume that would be comfortable/safe without them.

The downside is that every time someone wants to actually talk to me, I have to take my headphones off and take at least one earplug out.
