Alvin And The Chipmunks Use Moving Blankets
One of the other reasons people buy quilted moving blankets besides moving is to soundproof a room. There are very thick moving blankets that would work best to create a sound barrier. The majority of people who are trying to soundproof a room are musicians or part of a band like the cartoon Alvin and the Chipmunks did. Moving blankets are a quick and economical way to build a makeshift recording studio. If you purchase the thickest ones it can absorb up to 60% of the noise. Alvin, Simon, Theodore did this in their movie and you can use curtain rods all around a room and use them to hang the quilted moving blankets. If you are still not satisfies then you can always double them up.
