Are Soundproof Curtains Effective? (The Truth Revealed)

When it comes to soundproofing a room, installing soundproof curtains is one of the simplest and most affordable solutions. But are they really effective at blocking noise?

Soundproof curtains are very effective at absorbing echo and reverberation within a room. However, they are less effective at blocking loud exterior noises than purpose-built acoustic materials like soundproof doors and walls.

Moving on, in this article we’ll examine how soundproof curtains work, their key benefits and limitations, tips for choosing the most effective curtains, and how they can be combined with other treatments for optimal noise control. Let’s get into it.

How Do Soundproof Curtains Work?

Soundproof curtains are made from thick, dense fabrics like velvet, suede, or heavyweight polyester. The porous surface absorbs sound waves rather than reflecting them, which reduces reverberation and echo in a room.

The multilayered construction also creates a heavy barrier that obstructs external noise penetration to some degree. While not as impenetrable as professional soundproofing, quality curtains can decrease noise levels by up to 80-90% according to some manufacturers.

So while they won’t completely mute loud exterior sounds, soundproof curtains effectively deaden echoes and significantly muffle outside noise. To learn more, check out this guide on how sound absorbing materials work.

Key Benefits of Soundproof Curtains

There are several advantages to using soundproof curtains for noise reduction:

  • Affordable – Curtains cost much less than soundproof drywall or windows. Expect to pay $20-$100 per panel.
  • Easy installation – They mount on existing rods/brackets with no permanent modifications required.
  • Stylish – Choose from various colors and patterns to complement your decor.
  • Portable – Easily move the curtains to other windows as needed.
  • Some insulation – The thick fabric also provides some thermal insulation.
  • Absorbs echo – Greatly reduces reverberation and echo within a room.

For these reasons, soundproof curtains are a great inexpensive first step to treat noise issues in a space. Learn more about whether soundproofing really works in this in-depth article.

Limitations of Soundproof Curtains

However, soundproof curtains do have some limitations:

  • Not as effective for exterior noise – They don’t block loud outside sounds as well as purpose-built acoustic materials.
  • Heavy to install – The dense fabric can be cumbersome to hang and maintain.
  • Block natural light – When closed, the opaque curtains will darken rooms.
  • Must be closed – Gaps or billowing allow sound to penetrate through.

So in severe noise environments, soundproof curtains alone may not suffice. But for most applications, they provide meaningful noise reduction in an inexpensive, non-permanent way.

Choosing Effective Soundproof Curtains

Not all soundproof curtains are equal when it comes to noise blocking. Here are some tips for picking quality curtains:

  • Multiple layers – More layers increases density and absorption.
  • Heavy fabrics – Heavier curtains obstruct more sound. Look for 400+ GSM weight.
  • Tight weave – Tightly woven materials perform better than loose knits.
  • Full coverage – Floor-to-ceiling curtains with wide overlap are best.
  • Sealed edges – Prevents sound leaks around the perimeter.
  • Ceiling mounted – Mounting close to ceiling improves coverage area.

Some top brands for soundproof curtains include Nicetown, Nichiei, and H.Versailtex. Compare laboratory tested noise reduction ratings when available.

DIY Soundproof Curtain Tips

If buying specialty soundproof curtains isn’t feasible, here are some tips to make your own:

  • Use thick moving blankets or quilts for the fabric. Layer multiple for density.
  • Hang blankets with grommets or tape directly to walls around window.
  • Add mass loaded vinyl in between layers to block sound waves.
  • Seal all edges with acoustic caulk to prevent noise leaks.
  • Mount curtains on ceiling rods or tracks for best coverage.

While not as decorative, DIY sound blankets can also notably reduce noise. To learn about other natural sound absorbing materials, check out this helpful guide.

Using Curtains With Other Acoustic Treatments

For optimal soundproofing in spaces like home theaters or music studios, combine curtains with other acoustic treatments.

Some examples:

  • Install curtains to block exterior noise entering through windows.
  • Use absorption panels on walls to reduce reverberation.
  • Place bass traps in room corners to absorb low frequencies.
  • Seal doors and windows with sweeps and gaskets.
  • Float ceilings/walls for greater sound isolation if needed.

Together, these treatments can make rooms remarkably quiet. Though more labor intensive than just hanging curtains, the combination achieves superior noise reduction overall. Learn more about the difference between soundproofing versus acoustic treatment in this helpful guide.

“Major players in the soundproof curtains market include Acoustical Surfaces Inc., Great Lakes Textiles, Sound Seal, Steel Guard Safety Corp, Moondream, Quiet Curtains, Flexshield Group Pty Ltd, and Hofa” according to this market research.

Professional Soundproof Curtains

In severe noise environments where maximum blocking is essential, companies like AcousticCurtains make specialized soundproof curtains.

These commercial-grade curtains incorporate dense mass loaded vinyl layers from ceiling to floor. Some feature vinyl weighing 1 lb/sq. ft or more for superior noise control.

Though expensive at around $300-$500 per window, professional acoustic curtains can achieve noise reduction comparable to soundproof windows. They are ideal for notably noisy spaces.

“The revenue of the soundproof curtains market is expected to grow at a CAGR of 8.59% by 2029” according to this report.


While not as effective as purpose-built soundproofing materials, quality soundproof curtains significantly reduce noise and echo within a room. They provide meaningful acoustic absorption through an inexpensive, non-disruptive solution.

When combined with other treatments like bass traps and absorption panels, soundproof curtains create an optimal listening environment.

So if you’re looking to inexpensively dampen noise at home or work, installing soundproof curtains is a great first step!

Key Takeaways

  • Soundproof curtains absorb echo but don’t block exterior noise as well as other treatments.
  • Benefits include affordability, easy installation, and design flexibility.
  • Look for thick, multilayered curtains with sealed edges for best noise reduction.
  • For maximum sound blocking, combine curtains with additional acoustic treatments.
  • Professional soundproof curtains offer the highest noise reduction capability.

Frequently Asked Questions

Are soundproof curtains as effective as soundproof windows?

No, purpose-built soundproof windows with multiple panes and air gaps block more exterior noise than curtains alone. But soundproof curtains still provide meaningful noise reduction, especially for inside echoes, at a much lower cost.

How much noise do soundproof curtains block?

It depends on the quality, but high-end soundproof curtains can block 80-90% of noise versus regular curtains. More noise will penetrate than soundproof walls or windows, but it’s a significant improvement.

Should soundproof curtains touch the floor?

Yes, curtains should fully cover the window from ceiling to floor for maximum sound blocking effectiveness. Using a ceiling mount curtain rod provides the best coverage.

Where should I install soundproof curtains?

Bedrooms, offices, nurseries, and home theaters benefit most from reduced noise and echoes. Living spaces where the curtains must remain open are not ideal candidates.
