Hi, I can hear My neighbors TV loud at night, as well as her talking and her dog barking. How will be the cheapest most effective way of sound proofing my bedroom wall to stop her noise? Its only a 3 meter wall and i think its dot&dab. Also the best place to order the materials online? I had a look in b&q but they only had loft installation. I can do the work myself and was thinking of putting carpet tiles on the new plasterboard to save paying to have it plastered. I have made a quick diagram, the red line is where i can hear the noise. Thanks for any help.
