How to Reduce Noise from the Outside Inside Your Home


Although most modern homes are sufficiently insulated to keep noise transmission from outside the home at a minimum, older homes may need additional soundproofing. Interior noise, such as a loud furnace or noisy plumbing, can also be muted. A few simple materials are needed to turn a house into a quiet sanctuary.

Things You'll Need

  • Polyurethane caulk
  • Caulking gun
  • Utility knife
  • Acoustic foam
  • Staple gun
  • Explore the house for any open crevices and cracks. Typically located around windowsills or door frames, these small seams permit outside noise into the house.

  • Insert a tube of polyurethane caulk into the caulking gun. Fill any open seams with a thick, solid line of caulk. Allow all caulked seams to dry overnight or for the length of time suggested on the tube.

  • Cut several acoustic foam panels into strips of various sizes using a utility knife. Place these strips along windowsills, around door frames and along the corners of shared walls. Use the home's specific dimensions as a reference when cutting the foam.

  • Mount the foam in the areas mentioned above using a staple gun.

Tips & Warnings

  • To reduce noise transmission in new construction, ensure that proper soundproofing materials are placed within each wall (fiberglass insulation, gypsum board).
  • When attempting to reduce noise transmission in an apartment or rented space, consult the landlord before mounting foam panels or applying caulk to any seams.
