Hi guys, this is my first post here on this forum and thought i would let you all know what components i am using and what room i view my passion in. Its a dedicated building 8.5m x 5.5m and has a "hanson block outside wall structure" 200mm thick filled with concrete.It has been rendered then texture coated on the outside for appearances sake.On the inside i have placed timber batterns on the walls and lined them with 2 layers of "Boral soundstop plasterboard' 26mm thick(13mm each).The celing is a standard 8 feet and also has 2 layers of 13mm sound stop board and insulated with accoustic Gold celing bats rated at a value of 7.0.The carpet is an axminster commercial grade and the tiles are 400x400.There are no windows and there is 2 hardwood doors on a metal door frame to keep unwanted noise out. All work was done by myself except for the laying of the carpet.
