My DD is living in a student hall; the rooms are arranged as 'flats' with 5/6 bedrooms, with paper-thin walls. Everyone in hers is reasonably quiet except the boy in the room next to hers, who not only makes noise late but also has his alarm go off at 6 a.m. then leaves it on snooze until he feels like getting up, so it goes off every 9 mins. There have been a lot of complaints from others in the flat already but nothing is done about it, and he mocks anyone of the others who try to talk to him.
The point is, my DD - and the others - want to get their sleep so they can study. She has earplugs but they're not a lot of help, also if they damp the outside noise down too much she won't hear her own alarm go off. I wonder what to do? Speak personally to someone in charge of the hall?
Hire someone like Phil Mitchell to threaten him (!)
Or if not that, does anyone have experience of using acoustic foam?
I've got another 'keen'... Ouch!
