Answers:    ..i have answered this one various times ..the answers all ways impossible to tell apart ...first do NOT build the wall in timber ..it transmit nouns very resourcefully ..use metal studs ..available from most builders merchants ..set at 400mm ..infill with rock wool nouns proofing bats .. product sure you fill every perforation and you buy proper soundproofing bats ..these come within various thicknesses and i would move about for 75mm minimum ...the cover wall in nouns proofing plasterboard's ...these have a blue boundary ..this will stop 90% of sound...polystryene and uninteresting fibre cup are a wast of time and money
