The Peace Corps was formed by President Kennedy on this day in 1961. "Peace" and "quiet" are terms that go together, and soundproofing is how you can achieve that serene state. Think more insulation is all you need? Think again. There are four parts to better soundproofing. Adding insulation -- to absorb sound -- is just one. The other three? One is blocking noise with a non-hardening caulk to close-off airborne sound paths. Another is breaking the sound path using resilient wood studs with metal clips. The final step is isolating and eliminating vibration with special acoustical matting that isolates the wall structure from floor vibrations. You can get all four items needed all together in soundproofing kits for both interior and exterior residential walls. Besides blocking most noise transmission, an obvious benefit is better energy-efficiency with greater "r-values" that help both heating and cooling. If you want more peace and quiet, think insulation times four. Use them all and you'll keep noise outside and next door. And that's the On The House tip for today.
