hi i have just moved into a ground floor flat with 1 flat about above me i can hear everything comming from upstairs people talking arguing and even going to the loo which is disturbing i was wondering if i took the plaster board off and put loft insulation up and re boarded and plastered would this cut down on the noise as my flat is not soundproofed although there is concrete between me and the people above there is a good enough space between the concrete and my plaster ceiling could anyone please advise?
