DIY: Soundproofing Your Home Theater-Part Two

Last month's Part One on home theater soundproofing received an excellent response, including rather vociferous discussion on other sites (and in emails to me), encouraging the use of a substance called "Green Glue" in place of silicone caulk. Further research indicates there is a range of various soundproofing caulks and glues available from a variety of vendors at widely varying prices. To sum up, it's the sealing properties and elasto-viscous nature of these materials that all help, but do-it-yourselfers should be cautious about some extravagant claims made for some of these materials.

Specialty Materials

One reader sent along a link to which markets a popular specialty soundproofing drywall called QuietRock, comprised of three layers of viscoelastic, ceramic and gypsum material. QuietRock's QR-525, which incorporates these layers, claims to be remarkably effective -- one 5/8-inch layer of it is said to be the equivalent of up to eight layers of standard drywall and achieve STC ratings of "up to 72". It's certainly worth exploring these and other options.

That said, there is still no substitute for the tried and true construction techniques outlined in Part One -- staggered-stud walls with double layers of drywall on each side, interior wall cavities loosely filled with sound-deadening insulation, solid-core doors (or double doors), weather-stripping, using dissimilar materials and/or air spaces and so on.
