A) Producer’s Choice sound blankets are designed to absorb sound waves, especially of high and medium frequencies and reduce reverberation. These sound blankets are used, for example, in a room that has an echo as an acoustic room treatment.
If you use these blankets to hang over a window – it will dampen the incoming sound of the cars, but will not completely block it.
For better soundproofing, try one of our Window Sound Blocking Curtains. They are double thick to provide a superior sound blocking panel to quiet the room noise down to a more normal level.
