For under $100: earplugs, two kinds.

I got a pack of basic foam ones (supposedly 33dB reduction), and it meant that my wife and I could keep sleeping in the same bed without snoring getting in the way. Was only about $10 for 50.

And I got a pair of noise reducing Loop earplugs, which means that the one day a week RTO is no longer a sensory nightmare. They're visually subtle enough that my wife couldn't see them when I first tried them on (important if I was going to wear them in meetings), and recessed enough to wear underneath headphones. They're also great for large events (weddings and the like) to extend how long before my social battery gets wiped out. I imagine this is more tied to my autism than the office being particularly noisy though. I can still easily hold conversations with them in, with the only negative being that they kinda reduce spacial perception, so I can't as easily tell where sounds are coming from. These were about $50, though they've got cheaper options, they also come with extra mutes for more reduction, but the baseline is already plenty, so I'd probably recommend against the "Engage 2 Plus".
