Soundproof Your Room With These Cheap Building Techniques

Adding a laundry next to a bedroom may be convenient, but you better get used to hearing every door slam and washing cycle. During a remodel or new build, there are some inexpensive steps you can take to mitigate the sound travelling from one room to the next.

Sound travels better through air, so make sure your walls are well insulated and there is no empty space. Spray foam insulation is the most energy-efficient and best for sound deadening.

Before you close up the walls, wrap the electrical boxes with acoustical putty pads. You may need more than one to cover the entire box. This seal creates one less way for sound to transfer between walls.

The final step is to double-hang 5/8" drywall and use acoustical sealant. The acoustical sealant won't shrink, dry or harden, which will extend its life considerably over standard caulk. These final two steps will create an impressive barrier between rooms for little money.

An additional soundproofing tip: if a room houses a vertical drainpipe through the wall, use cast-iron for those pipes instead of PVC. With PVC drainpipes you can hear water rushing through on every flush, but with a cast-iron pipe it will be silent. Check out the video above for more.

    "Sound travels better through air"

    Sorry, sound sound travels further and faster through liquids and solids than air.

      Yeah I don't know where he got that from.
      Though transition from one medium to another does attenuate the sound.

      Exactly; you're better off creating a vacuum between objects that make noise and where you are.

    Rigid spray foam insulation is terrible for sound insulation. Fluffy batts are much better.

    Steel studs are better than timber studs.... (don't know if that's referenced in the video or not, didn't watch, as designing soundproofed partitions is (part of) my job)

    Everyone has a room in the house they wish they could make their own room with soundproof. This blog helps to soundproof room with simple building techniques. Thanks for sharing this blog!!!

    Creating acoustic panels is certainly better then purchasing them. For two main reasons, one, they can be customized and the two, they become really affordable.
