Weatherstrip Windows Windows and doors tend to be the weakest link in your sound defense. Weatherstrip all points where sashes meet jambs, headers, and sills. In addition, fill any tiny gaps around moldings with an acoustical caulk sealant.
trick for small windows - mount a mirror lengthwise under the window, then hang floor length window panels from above the window. Place a lamp in the middle of the dresser to camouflage the mirror and help integrate it with the window above.
