I need silence, or white noise. If I hear talking, or sound effects, I can not sleep at all.
I keep 2 pcs in my master bedroom, and these 2 boxes are kept on at all times. The hum of the computers makes it so that I don't hear the neighbors in the townhouse next door when they run up or down their stairs, and I don't hear the cars that have too much bass so bad. I would prefer silence, however, that's impossible to achieve here, so white noise will do.
I have never in my life been able to fall asleep with a tv on or music on.
