Best way to soundproof a room?
For a bedroom that is on a very noisy street with large windows (sliding door in one of them), What is the best way to soundproof the room. I do not care that blocks the view of that particular room.
Concrete is one of the obstacles better sound. Plexus Multi often use concrete between floors and ceilings of the upper and lower levels, and horizontally between the walls that divide the housing units. Also You can add another panel to replace the glass or glass with a larger volume of glass, with pockets designed to help block the sound. A quick and easy adjustment would be make heavy curtains "sound blankets". Sound blankets are really heavy quilted packing blankets used by the film industry to absorb sound Junk and also to eliminate hollow sounds echo through the removal / rebound. They are a great muffler. You could try to rent houses film crew or packing moving companies.
