Having lived in the dorms during college, I know exactly what you mean by no peace. What I had to do sometimes was just take a long bath with a radio in the bathroom. It might drown out some of the noise. I dont know how things are in your home, but have you tried making them take it outside? Perhaps if everytime there was an argument and they had to take it outside in the cold, they might be less likely to be so loud about it.
