Sound Reducing methods utilizing Drywall

Updated: Dec 17, 2022

There are several methods that can be used to help soundproof a basement using drywall. Here are a few options to consider:

  1. Install sound-absorbing material: First and foremost, you should insulate to help improve sound insulation in a basement. Don't skimp on this vital step! These materials can be installed in the walls or ceiling to help absorb sound waves and reduce noise transmission. Blown-in Cellulose is recommended by most insulation proffesionals. Consult with a qualified insulation contractor when choosing the right insulation method for your needs and budget.

  2. Upgrade your regular 1/2" drywall for 5/8" Type X drywall: Not only will it provide some sound reducing benefits, 5/8" Type X drywall is engineered for fire and will provide 1 hour of fire protection where 1/2" drywall is only rated for 20 minutes.

  3. Install double layers of drywall: One effective way to improve sound insulation in a basement is to install two layers of drywall preferably 5/8" Type X.

  4. Use sound-resistant drywall: Specialized drywall products, such as QuietRock or SilentFx, are specifically designed to improve sound insulation in walls and ceilings. These products typically have a denser core and a thicker paper backing, which help to reduce noise transmission.

  5. Use resilient sound isolation clips and hat channel: Sound isolation clips and hat channel are metal brackets that are used to decouple drywall from the framing behind it. By separating the drywall from the framing, these products help to reduce sound transmission through the wall. This method is recommended when sound transfer such as walking is what you are looking to reduce.


Overall, the best method for soundproofing a basement will depend on the specific needs and characteristics of the space. It may be necessary to use a combination of these techniques to achieve the desired level of sound insulation.
