Eli5: Why are peoples’ own noises and smells usually dialed down, such as not being affected by their own snoring and not noticing their body odor?

Question

Why does the brain seems to dial down things that we produce; even the obnoxious snoring or noises made while sleeping don’t affect us? Similarly, people don’t usually get annoyed by their own talking or yelling to themselves.

My boyfriend actually *does* wake himself up from his own loud snoring. It’s hilarious most of the time. It’s totally possible to affect yourself with snoring or BO, but I’d imagine that over time, you’d get used to whatever your status quo is and would just tune it out, like you do the noise the fridge is making all the time.
