I wonder whether you can help.
I am looking for a DIY or an affordable soundproofing insulation solution to the impact thudding sounds that seems to be travelling along the wood laminate floor of my flat from my neighbour next door to me dropping weights on his floor.
I have had acoustic membrane / barrier shield and acoustic plasterboard added to the wall already, which has improved the acoustic insulation of the wall, and I have some spare Barrier shield left over.
I have also added foam underneath the legs of my bed which has also helped a little to absorb the vibration from the dropped weights. But the noise still remains.
