The university dormitory is originally a public area, where everyone has the right to speak, if you like quiet. When you are noisy at night, you can wear headphones to listen to some songs, do some exercises and read some books, because everyone has his own right to speak and you can't control others. Besides, everyone is an adult and can't talk about others, so you should adjust your life and try to stay in the library during the day instead of going back to the dormitory. After all, the dormitory is not so quiet. You should like quiet words.
