proper sound booth either solid or material

Thanks for the blankets!! They work very well. They are almost twice the size of the window so I doubled each one and draped them over the compressed rubber sheets that fit snugly in the window frame. The birds have been cancelled out and 75% of aircraft noise too so I am delighted. If this new venture of mine does well then I shall go in for a proper sound booth either solid or material. Bottom line is cost really!!!

Thanks again for the good customer service.
