If you have a home workshop in the basement or garage, it may be necessary to reduce noise through soundproofing. Soundproofing helps keep those inside your house and your neighbors stay comfortable while you’re working with your power tools like your diamond blade saw. It may also be needed to adhere to your area’s local safety laws and regulations.
Engineers measure sound in decibels or dB. The lower dB, the quieter the sound. Most of your power tools will churn out 85 to 100 dB of sound while you’re using them which is the same as a noisy manufacturing plant.
If you’re looking for a cost-effective and viable solution that can help you reduce noise from your workshop, here’s what you can do:
Removing or Repairing Cracks that Can Leak Noise Out
Your drywall can absorb a considerable amount of sound. However, holes in the walls or ceiling can be a way for sound to leak out. To seal up the walls, you can use drywall tape and a joint compound which can cover the board-to-board cracks on the wall. With these cracks covered, using fire code compliant drywall which is 5/8” thick can help absorb more sound. Also, consider adding flexible acoustic caulking which can contribute to preventing more sound leaks.
Improving the Sound Resistance of Your Walls and Ceilings
The resistance of your walls to sound leakage is measured in Sound Transmission Class (STC). The greater the STC, the better the material is at block sound. A typical drywall is ½” with an STC of 30. That isn’t enough to keep your workshop noise within the room.
To improve the sound resistance, you can consider installing the 5/8” thick fire code compliant drywalls over metal strips called resilient channel. These fasten onto floors joists and separate the drywall from the wood which helps in blocking sound transmission better.
Also, consider adding fiberglass batts between the joists before you add the drywall so you can boost your workshops STC to about 50.
With these techniques, you can perform all your usual workshop projects without worrying about your family or neighbors complaining about the noise. For more information on power tool applications or safety tips, check out GilaTools.com!
