When I'm in a social setting and tell people it's time for me to leave, people are landscaping outside, running a kitchen vent fan, or a baby is crying.
I turn mine on and it becomes the background baseline drowning out so much other noise I often forget it's on until a while later when I'm like "why can't I hear anything?" 😂
The one at my brother’s place doesn’t bother me, but he lives in a brand new house. The one at home? I have to wear my airpods pro on noise cancelling while I cook. Otherwise I end up grating my teeth and getting heart palpitations from panicking without realising why.
My pup is terrified of the kitchen vent because he associates it with burning food and the omg loud fire alarm. He's the only one I know IRL that's bothered by it.
Bathroom fans, on the other hand, bother TF out of me. I've never lived with one that wasn't too loud to run. And I don't have enough spoons to spend a few on replacing my current one with a quieter one, so it just sounds like gravel.
