Hiya guys, i want to soundproof an internal wall, what is the best and easiest way to do it, i was going to use some soundproof boards and dot and dab them to the wall, but i have seen videos where people mount them on battens and stuff, is that really necessary? is the barrier more effective with a gap between the boards and the wall? and also, will my plasterer be able to plaster straight over them?
thanks in advance guys...
