Roommate conflict

Any creative ideas to address roommate conflicts? My daughter’s really struggling with her roommate having the TV volume up too high while she’s trying to study… Any suggestions?

Can they agree on quiet hours? Are there other places to watch TV/study close by? Like if the dorm has a lounge, TV watcher could go watch there during quiet times. Can studier move to a quiet place when the key TV shows are on? Or does roommate like to study with the TV on in the background? If yes, how about headphones for roommate?

We have Roku at our house which allows someone to watch TV with headphones. Is that a possibility?
