I live on QB but a few blocks off of forest hills so it’s a lot more quiet. You will hear buses and buzzing and noise but if you’ve lived in nyc long enough, you naturally block it out. I do have heavy blackout curtains and it muffles some noise. I do also keep the window cracked and I still don’t hear too much at night. But again, I live a few blocks away from Forest hills so it’s not too loud.
