Hi, Ok, my new neighbors have 2 young kids that constantly run up and down the stair and bang about constantly and it’s driving me crazy! Had older couple before and was great! Now I feel constantly on edge and want to punch a hole through the wall and tell them to shut the **** up. But it’s kids.. and I can’t ask them to stop playing.. It’s a new build house with a brick dividing wall with timer and plasterboard walls. Their stair case runs down the side where the party wall is and can constantly hear them thumping about. It must be noisey as hell in that house! Put my ear up against the wall and all I could hear was screaming.. Is there any insulation or sound proofing I can install behind my plasterboard walls to cut out this noise!? People are saying aucostic sound proofing won’t work in reviews I’ve read. Would thick slab insulation cut out the noise and banging? I’m willing to take down all my plasterboard walls in the party wall to install soundproofing but not sure what to get! Help!!
