My house is a semi and I soundproofed my bedroom party wall with battens to wall, insulation inbetween, resilient bars and 2 layers of 15mm plasterboard with membrane sandwhiched inbetween and its done naff all. I can still hear the neighbours washing machine and kettle boiling in their kitchen from my upstairs bedroom so i've built a stud wall in my kitchen 75mm off the kitchen party wall, insulated inbetween and 1 layer of 15mm plasterboard and again its done nothing. I can constantly hear doors banging, the female arguing, draws in the bedroom closing, washing running at 4am on a morning, female singing like a strangled cat, the list goes on.
Everything i've done hasn't worked. What am i doing wrong? will i need to soundproof the living room and second bedroom which are divided by the neighbouring party wall to see/hear any difference?
Many thanks
