Hello. What's the best way to soundproof my bedroom(keeping the sound in)? The main issue is the door as it is very hollow. It it advisable to carpet the door? or are there other alternatives that are under $100? If i were to carpet the door, what would be the best material to use and where can i find it most cheaply? Thanks
just squeeze both side, and pull the cover off, try doing from where the trunking begin. but if it is old or not so good quality, u may have problem putting it back
