Garages aren’t just for cars anymore. Many people use their garages as home offices, studios, or workshops where soundproofing is essential. Whether you’re a musician needing a practice space, a woodworker tired of complaints about noisy equipment, or a fitness enthusiast creating a home gym, soundproofing a garage can transform your space into a quieter, more functional area.

In this guide, we’ll walk you through how to soundproof a garage and explore effective garage soundproofing techniques that keep noise from disturbing neighbors or other household members.

Why Soundproofing a Garage Matters

Garages often amplify noise due to their hard surfaces and lack of insulation. Without proper soundproofing, activities like band practice, loud machinery, or even hosting gatherings can lead to excessive sound transmission. Soundproofing your garage ensures:

  • Reduced noise transmission to neighboring homes or rooms.
  • Improved acoustics for music practice or recording.
  • Enhanced comfort for any activity that requires focus and minimal distractions.

How to Soundproof a Garage: Step-by-Step

Soundproofing a Garage - Be sure to insulate the structure of the building. This will help the overall STC rating of the structure.

1. Soundproof the Garage Door

Garage doors are one of the largest openings in your space, making them a significant source of sound leakage.

  • Seal Gaps and Cracks: Use a weatherproof seal along the edges to prevent sound from escaping.
  • Install Acoustic Blankets: Cover the door with PrivacyShield® Sound Blankets to absorb and block sound. These blankets are easy to attach and provide excellent soundproofing without permanent modifications.
  • Add Mass: Consider attaching AudioSeal® Mass Loaded Vinyl (MLV) to the door’s interior. This heavy, flexible material helps block sound transmission effectively.

2. Treat Garage Walls

The walls of most garages are thin and lack insulation, making soundproofing a must.

  • Install Soundproof Drywall: Double-layered drywall with a sound-damping compound like Green Glue sandwiched between is a popular choice for reducing sound transfer.
  • Use Acoustic Panels: Add AlphaSorb® Acoustic Panels to absorb sound inside the garage and reduce echo. These panels are available in customizable colors and sizes to match your space.
  • Insulate the Walls: If your garage walls are unfinished, fill them with dense insulation like rockwool to absorb airborne noise.

3. Soundproof the Ceiling

If there’s living space above your garage, soundproofing the ceiling is important to minimize noise transfer.

  • Install Ceiling Panels: Use AlphaSorb® Fabric-Wrapped Acoustic Ceiling Panels for effective sound absorption.
  • Add Insulation: Install fiberglass or rockwool insulation between ceiling joists to dampen sound.
  • Decouple the Ceiling: Use resilient channels to separate the drywall from the ceiling structure, reducing vibrations and sound transfer.

4. Address the Garage Floor

Floors often amplify impact noise, especially if you’re using heavy equipment or exercising.

5. Seal Doors and Windows

Small gaps around doors and windows can allow sound to escape.

Garage Soundproofing Tips for Specialized Use Cases

For Music Studios

For Workshops

  • Surround noisy tools with PrivacyShield® Sound Blankets to isolate sound.
  • Add vibration isolation pads under machinery to prevent noise transfer through the floor.

For Gyms or Fitness Areas

  • Use rubber flooring and wall-mounted acoustic panels to control impact noise and echo.
  • Ensure weights or equipment don’t vibrate against bare walls or floors.

Common Mistakes to Avoid When Soundproofing a Garage

  • Ignoring Gaps and Cracks: Even small gaps can undermine your efforts. Use sealants and acoustic caulking for complete coverage.
  • Relying on Single Solutions: Combine absorption (acoustic panels) with mass (MLV or drywall) for the best results.
  • Seal Around Outlets: If the walls will have electrical outlets and switches, now would be a good time to seal the gang boxes with something like putty pads.
  • Overlooking the Garage Door: This is one of the biggest weak points for sound leakage.

FAQs About Garage Soundproofing

1. Can I completely soundproof my garage?

While you can significantly reduce noise transmission, achieving complete soundproofing may require professional construction modifications.

2. What’s the best material for soundproofing a garage?

For blocking sound, Mass Loaded Vinyl (MLV) is highly effective. For absorption, AlphaSorb® Acoustic Panels and PrivacyShield® Sound Blankets are excellent choices.

3. Is soundproofing a garage expensive?

It depends on the size of your garage and the materials used. DIY solutions like sound blankets and acoustic panels can be budget-friendly compared to full-scale renovations.

Thank you! We are opening a coworking space and want our conference rooms “sound-blocked” but also want to create a podcast booth for recording. I learned so much from you!
