Ish. 30-40db in my bedroom. Unfortunately I live in a very noisy building in the middle of tourist hell. I did get a white noise machine when I unplugged.
"Do you sleep in a loud environment?"
If one's home is quiet, it makes it more likely that one wakes up if a car drives by in the middle of the night, or if a neighbour starts up his/her car in the morning.
Mmm yes! When I was sleeping without plugs, it was very frustrating to hear neighbours. My building has 21 apartments, 11 of which are AirBNB. There are drunk people coming home in the small hours, as well as people getting up for flights and work a bit later. I can also hear cars from the street. No plugs was very tough. I don't think I could go back to not sleeping with plugs unless I moved somewhere very quiet.
