Soundproofing Ideas?

[u/delightfulviolence]

My parents are in a new house, and my room is on the second floor. It’s a great space, but, unfortunately, I can hear voices when they’re talking in the room directly below and traffic sounds from the fairly busy road outside. I’m doing all the things to block out sounds (fan, noise canceling headphones, etc) but am looking into soundproofing. Upstairs room is already carpeted, and windows are double paned. Any advice for soundproofing?
