Auralex offers a number of products to help with sound isolation. Please note that our Studiofoam, ProPanel, and other Absorption products are primarily used to help control reflections and standing waves inside the room, not for isolation purposes. Sound isolation is the reduction of sound transmission from one space to another. This generally requires construction materials, and may involve remodeling your space.
For a basic explanation of Sound Isolation read this, for more information regarding Construction/Isolation Products view our Quick Guide and for in-depth Sound Isolation build-out information please refer to Acoustics 101, particularly Chapters 3 and 4 and/or view our FAQ.
