I had to use ear plugs at some of the jobs I had when I was working, as they were noisy places. I don't need them now, as I live alone, and don't go out much. It is easier to take the noises when I am out now that I know I can go home to a quiet home, as I now live alone. My place is a haven for me. Of course, there is noise from the neighbors, but it's not too bad. When I sleep I do use white noise though, to help blur other noises. I get it by tuning the radio to static instead of a station. That definitely helps blur the other noises, so they are less intrusive when I am sleeping.
