A while back, a customer came to us needing a quiet space to record voiceovers from home. His issue? Too much background noise in his apartment, paper-thin walls, and constant traffic noise. He wasn’t ready to invest in a studio rental or major remodel. What he needed was a personal, sound-isolated space he could build himself. That’s where the concept of a DIY soundproof booth came in. As a musician, podcaster, remote worker, or content creator, having a quiet space to focus or record clean audio makes a big difference in your work. In this article, we’ll walk you through how to build your own DIY soundproof booth—and also share when a ready-made booth might be the better option.

Should You Build or Buy a Soundproof Booth?

Before you dive into construction, ask yourself: should I build a booth from scratch or buy a pre-assembled model?

DIY Soundproof Booth Pros:

  • Lower cost
  • Full customization
  • Great for tinkerers and hands-on builders

DIY Soundproof Booth Cons:

  • Time-consuming
  • Requires basic construction skills and tools
  • Can be difficult to get truly soundproof without the right materials

Pre-Made Soundproof Booth Pros:

  • Quick setup
  • Professionally engineered for performance
  • Portable and modular options available

Pre-Made Soundproof Booth Cons:

  • Higher initial investment
  • Fewer customization options

If you're short on time or want plug-and-play performance, check out Acoustical Solutions’ line of modular soundproof booths, office pods, and isolation enclosures—designed for serious acoustic control right out of the box.

Planning Your DIY Soundproof Booth

Start by defining your goals. Are you creating a vocal booth? A private office pod? A content creation space? Your booth's function will impact the size, layout, and material choices.

Key planning questions:

  • How much space do you have?
  • Will the booth be permanent or portable?
  • Do you need room for a desk, mic stand, or chair?
  • Do you need ventilation?
  • What is your budget?

Also, be realistic about your skill level. If basic framing, insulation, and finishing are new to you, keep your design simple—or consult a contractor.

Materials You’ll Need

Here’s what goes into a basic DIY soundproof booth:

  • Framing Lumber—Usually 2x4s to create the structure
  • Mass Loaded Vinyl (MLV)—Blocks sound transmission (we recommend AudioSeal® Mass Loaded Vinyl (MLV) Soundproofing Barrier)
  • Insulation—Use mineral wool or fiberglass batts to absorb sound inside the walls
  • Drywall, MDF, or Plywood—Sheathing for both interior and exterior surfaces
  • Acoustic Caulk or Sealant—Seals gaps to prevent sound leaks
  • Soundproofing Foam or Panels—Improves sound quality inside (e.g., PrivacyShield® Soundproofing Composite Foam>)
  • Solid-Core Door—Better at blocking sound than hollow-core doors
  • PrivacyShield® Door Seal Kit—Prevents sound leaks around the door
  • Ventilation Kit (Optional)—Ensures airflow without sacrificing sound isolation

How to Build a DIY Soundproof Booth

If you’re planning to build your own booth from the ground up, the following steps will walk you through the basics—from framing to sealing and treatment. These DIY methods give you complete control over size and materials.

1. Build the Frame

Construct a simple wooden frame for your walls, floor, and ceiling using 2x4s. Design it modular if you plan to move it later.

2. Add Insulation

Fill each wall cavity with high-density acoustic insulation. This absorbs sound within the structure.

3. Add Mass-Loaded Vinyl (MLV)

Apply MLV over the insulation and framing, ensuring full coverage. Overlap seams and seal edges with acoustic caulk.

4. Close the Walls

Attach drywall, MDF, or plywood over the MLV. Double layers will offer better sound isolation.

5. Seal the Seams

Use acoustic caulk at every seam, joint, or opening—including corners and where the ceiling meets the walls.

6. Install the Door

Use a solid-core door with proper framing, and apply the PrivacyShield® Door Seal Kit to block air gaps.

7. Treat the Interior

Use foam, panels, or bass traps on the interior surfaces to prevent reflections and create clean sound. AlphaSorb® Composite Foam is great for this.

Ventilation Tips for Soundproof Booths

A sealed booth needs airflow—but you can’t just cut a hole and call it a day.

Options:

  • Use a quiet inline fan with ducting to move air silently
  • Build a baffled air vent using MDF and acoustic foam
  • Run passive air ducts with turns and absorption inside to reduce sound leaks

Just make sure air enters and exits without compromising isolation.

When a Pre-Made Soundproof Booth May be the Better Option

DIY booths are cost-effective, but they’re not always easy. If you’re:

  • Short on time
  • Uncomfortable with tools
  • Concerned about the finish quality
  • Needing something portable or reconfigurable
…then a pre-fabricated booth may be the better route. At Acoustical Solutions, we offer modular soundproof booths, vocal isolation pods, and office enclosures that are ready to install with minimal effort.
