we live in a 1900s terrace house and both us, and now our neighbours have bare floorboards in the adjacent bedrooms. I have read the other posts on here and have come up with a plan to minimise the transmitted sound, but was hoping for some advice from some wiser souls.
The wall itself already has sound insulating board on it with a skim on top, so the sound appears to transmitted through the floor. My plan is to lift the boards near the wall and check for any holes in the mortar and fill if required, then to stuff the gaps between the joists with acoustic wadding/ high density rockwool stuff at that end of the room. Would there be any benfit in doing the whole floor as it is just sound from next door which is the problem. My concern is that maybe the joists (ours and the neighbours) are butted up against each other in the wall, in which case doing what i suggest wouldnt make any difference. Do they usually butt the joist up together or is there usually a gap? Clearly putting carpets down would be a simple solution but we really like the look of the floorboards. Any advice would be greatly appreciated. Thanks
