"And you would realize how much noise people make." Confirmed! It's not even an "it depends.." imho. Humans are noisy, period. As an excercise: find a place outside, where for a full day you won't encounter, see or even hear another human. Maaany bonus points if not even encountering signs of human presence like traffic noise, litter, an airplane flying overhead, pipelines / power grid, marked trails, a radio tower in the distance, or whatever. FYI: in the Netherlands, you basically can't.
