Exactly. My desk is next to my dryer, which is currently running, and my furnace is in a closet behind me. ANC helps block those noises, which would be inescapable otherwise unless I wanted to play my music way too loud.
Yeah, same with three kids here (although it does mean people on video calls hear them, or in one case a fire alarm, before I do). I have to admit I will sometimes wear them either way though, I feel it helps me focus.
