My flatmate has decided to take up the hobby of opera singing, especially late at night. He isn’t very good, IS very loud (could hear him singing outside and I know someone who lives next to us and she said she could hear him when I mentioned it) and doesn’t actually sing the words (just la la la and making noises). We live in quiet accommodation so when he was singing at gone 10:30 the other night I asked him to be quiet and he refused and was quite rude about it (I sent a message on the gc asking for the music to be turned down, not naming him). He has since been regularly singing VERY loudly past 10:30 and 11 at night. Does anyone know what I can do? I feel like I might go insane if he doesn’t pack it in. There must be places on campus he can go to sing. Am I right in thinking it is inconsiderate to sing in such a loud manner in quiet accommodation?
