The soundproofing is apparently non existent between myself and next door but in addition to this, their door slamming and loud voices dont help. I feel like I live in the same house as them. I hear the lightswitch go on (clear, not muffled), their conversations - not always word for word but if its late at night then I can clearly hear their conversations. They seem to enjoy lengthy phone calls, perhaps they are shouted across the room. I’m just tired of it and feeling like I know their every move but mainly having to follow their sleep (or lack of) patterns. Being kept awake til midnight/woken during the early hours at the weekend listening to talking/shrieking style laughs. I am a light sleeper so that doesn’t help. I now put my tv on louder to drown them out and use white/brown noise but I wonder if there are other suggestions. I have tried earbuds but they hurt my ears so can’t sleep in them. I have put a polite note through the door and knocked and explained and the person was polite back and “oh no, oh dear” but nothing has changed really. It isn’t ridiculously loud constant parties but it is affecting me. Any advice appreciated!
