noise complaints!!! help

i live in a small area of student properties surrounded by ‘normal’ residential homes and flats. my student neighbours party every weekend without fail and all our homes have been receiving letters complaining about the noise with threats to call the police and contact the council, letting agency and university. the uni have already been contacted once and we had an email threatening to take action if another complaint came through. thjs is super distressing and upsetting because we haven’t been making any noise, its the other properties and although its probably so stupid its really making me anxious. i would try speak with the neighbours but there is no name or house number on the letter, its just signed with a street name. ive spoken w the other students and they dont seem to care much about making noise which is on them, if they get in trouble thats expected but i dont wish to get the blame too. has anyone else been in a similar situation?? how do you handle it?
