Unsure why you're being downvoted, but in my experience, this is absolutely correct. When I lived on a busy intersection, the noise level was always there, it just became background. When I lived near a flightpath, the sound of airlines was regularly there, and it also just became background. I now live in a very quiet area, and every passing motorbike is a disturbance. Then again, the other thing that's changed is my age and expectations of life. Whether or not that's related or not, I dunno.
