Wear headphones that are comfortable to wear for a long time (like big ones that go all around your ear but don't press on your earlobes) and use a white noise generator. I use one that adds like rain and thunder and campfire so it sounds like I'm in a log cabin during a storm and I just crank up the volume to where it drowns everything else out. Literally right now there is jackhammering going on in my office and I can't hear it at all until I take my headphones off. (I use asoftmurmur.com personally but anything should be fine)
