It depends on background noise, not sure how objectively it can be measured.
My apartment is super quiet, you hardly hear anything from the outside, so I can hear a HDD in the living room during the silent parts of movies. In some relative’s house, however, you only notice how loud is the background noise when the power goes off. No wonder why I always have a headache when I go there.
