But while the internet is full of quick fixes and miracle products, the truth about home office soundproofing is often clouded by myths. Misinformation can lead to wasted money, time, and persistent frustration when your workspace remains noisy and distracting.

In this comprehensive guide, we’ll dissect the most common myths about DIY soundproofing for home offices. You’ll learn which strategies actually work, which are a waste of effort, and how to make targeted improvements using proven techniques. This article is packed with practical insights for homeowners of all skill levels, whether you’re setting up a new office or seeking peace in an existing space. Let’s cut through the noise and build a quieter, more productive environment together.

Myth #1: Egg Cartons Are Effective Soundproofing

Where the Myth Comes From

Egg cartons have been touted for decades as a cheap, DIY soundproofing hack. The idea is that their bumpy shape “absorbs” sound, similar to professional acoustic foam.

The Reality

While egg cartons may slightly diffuse high-frequency sound, they do not block or absorb noise in any meaningful way. They lack the density and material composition needed to prevent sound transmission through walls or doors. Professional acoustic foam, in contrast, is engineered for absorption and usually works in tandem with other materials in a full soundproofing system.

What to Do Instead

  • Use real acoustic panels: Install high-density foam or mineral wool panels designed for sound absorption.
  • Add mass: Use dense materials (like drywall, mass loaded vinyl, or insulation) to block sound transmission.

Myth #2: Thick Curtains Alone Can Make a Room Soundproof

Why This Is Misleading

Heavy curtains, sometimes sold as “soundproof” drapes, are widely marketed to block street noise. It’s true that they can help reduce echoes and slightly muffle high-frequency sounds, but they do not block low-frequency noise or prevent sound from passing through windows and walls.

The Real Effect

Thick curtains are best used as part of a larger soundproofing strategy. They reduce noise reflections within a room (improving acoustics) but don’t block sound transmission from outside. For real sound isolation, you need to address the entire window assembly and other weak points in the room.

Better Approaches

  • Seal window gaps and install weatherstripping.
  • Consider secondary window glazing or interior window inserts.
  • Pair curtains with other strategies for best results.

Myth #3: Acoustic Foam Stops Sound From Entering or Leaving a Room

The Source of Confusion

Acoustic foam is a staple in music studios and is often mistaken for a sound-blocking material. In reality, it’s designed to improve sound quality within a room by absorbing echoes and reducing reverberation, not to stop external noise from entering or leaving.

The Science

To block sound transmission, you need mass and airtight seals. Acoustic foam is lightweight and porous, so it’s excellent for acoustic treatment (improving how sound behaves inside the room) but ineffective for actual soundproofing (keeping outside noise out, or inside noise in).

What Actually Works

  • Add mass to walls: Use extra layers of drywall or mass loaded vinyl.
  • Seal gaps and cracks: Use acoustic caulk around outlets, windows, and baseboards.
  • Isolate structure: Use resilient channels or isolation clips to decouple drywall from framing.

Myth #4: Any Door Can Be Made Soundproof With Weatherstripping

Partial Truths

Weatherstripping is a useful tool for blocking air—and sound—leaks around doors. However, if your door is hollow-core (as most interior doors are), sealing the edges will not stop sound from passing through the door itself. Hollow-core doors are lightweight and transmit noise easily.

How to Truly Soundproof a Door

  • Install a solid-core door: These are much heavier and block significantly more sound.
  • Add door sweeps and perimeter seals: Ensure the door is well-sealed on all sides, including underneath.
  • Consider door gaskets for maximum performance.

Myth #5: Carpets and Rugs Can Fully Soundproof a Home Office

The Origin

It’s true that carpeting and thick rugs help absorb sound and reduce echoes within a room, making it feel quieter. However, they are not effective at blocking sound transmission through walls, floors, or ceilings.

What They Really Do

Carpets and rugs are excellent for improving room acoustics and minimizing impact noise (like footsteps), but they don’t stop airborne noise from neighbors, outside traffic, or adjacent rooms.

Complementary Solutions

  • Use in conjunction with wall and ceiling treatments.
  • For floor-to-floor noise, consider adding underlayment or soundproofing mats beneath flooring.

Myth #6: Soundproof Paint Is a Miracle Solution

Marketing vs. Reality

Soundproof paints are heavily marketed as easy fixes for noisy rooms. While they do contain additives that can slightly dampen high-frequency sounds, their effect is minimal—usually only a 1-3 decibel reduction, which is barely noticeable to the human ear.

When (and When Not) to Use

Soundproof paint is not a substitute for proper soundproofing construction. It’s best used as a minor supplement, not a primary solution.

Smarter Alternatives

  • Prioritize adding mass and air-tight seals over paint-based solutions.
  • Reserve soundproof paint for small, targeted improvements.

Myth #7: More Insulation Means Total Silence

The Insulation Fallacy

While insulation (like fiberglass batts) helps reduce sound transmission, it is not a magic bullet. Insulation absorbs some airborne noise between wall cavities but does little to stop low-frequency noise or impact sound unless paired with other methods.

How to Use Insulation Effectively

  • Use high-density insulation (mineral wool or rockwool) for superior sound absorption.
  • Combine with double drywall, resilient channels, or sound-damping compounds for real results.

Myth #8: DIY Soundproofing Is Always Cheaper and Just as Good as Professional Work

Balancing Budget and Results

DIY soundproofing can be highly cost-effective for minor improvements, such as sealing gaps, adding rugs, or installing door sweeps. However, for complete isolation or if you’re dealing with complex noise issues (like shared walls or ceilings in multi-family housing), professional assessment and installation may be necessary.

When to DIY and When to Hire Pros

  • DIY is suitable for: Addressing small gaps, installing thick curtains, or adding surface treatments.
  • Hire a pro for: Structural changes, complex wall/ceiling assemblies, or if building codes and permits are required.

Effective DIY Soundproofing Strategies That Work

Seal All Air Gaps

Use high-quality acoustic caulk to seal gaps around electrical outlets, baseboards, window frames, and anywhere air can leak. Even tiny cracks can transmit surprising amounts of noise.

Upgrade Doors and Windows

  • Replace hollow-core doors with solid-core models.
  • Add weatherstripping and door sweeps.
  • Install window inserts or secondary glazing for better noise reduction.

Add Mass to Walls

  • Install additional layers of drywall, ideally with sound-damping compound (like Green Glue) in between.
  • Mass loaded vinyl (MLV) can be added behind drywall for extra performance.

Isolate and Decouple Structures

  • Use resilient channels or isolation clips to separate drywall from framing, limiting vibration transfer.
  • Install floating floors or isolated ceiling assemblies in extreme cases.

Improve Room Acoustics

  • Install acoustic panels or thick wall hangings to tame echoes.
  • Use plush rugs and heavy curtains as secondary acoustic treatments.

Frequently Asked Questions About DIY Soundproofing

Does soundproofing always require major construction?

No. Many effective soundproofing steps, like sealing gaps or upgrading doors, can be done with basic tools and materials. However, for maximum noise isolation, adding mass and structural decoupling may be necessary.

Can I combine different methods for better results?

Absolutely. The best soundproofing solutions are layered—combining absorption, mass, and air sealing for comprehensive results.

How do I test if my soundproofing is working?

Use a smartphone decibel meter to measure before-and-after noise levels. Also, listen for specific problem noises and see if they’re reduced after improvements.

Conclusion: Building a Quieter, More Productive Home Office

Soundproofing your home office is crucial for focus, productivity, and even your sanity—especially in today’s world of remote work. But separating myth from reality is the first step towards meaningful improvement. Egg cartons, carpets, and miracle paints won’t deliver professional results, and relying on them can lead to disappointment and wasted resources.

28 thoughts on “Common Myths Debunked: The Truth About DIY Soundproofing for Home Offices

  1. I’ve heard a lot about using egg cartons for soundproofing, so I’m surprised they don’t really work. For someone on a tight budget, what’s the most affordable alternative to egg cartons that actually helps block noise between rooms?

    1. Egg cartons are a common myth but don’t actually block sound effectively. For a budget-friendly alternative, try using thick moving blankets or heavy curtains on shared walls or doors. Adding a bookshelf filled with books against the wall can also help absorb sound. These solutions are inexpensive and offer much better noise reduction than egg cartons.

  2. I’ve tried some DIY hacks in my office and it still feels noisy. Based on what you shared about egg carton and curtain myths, what are the first two changes you would recommend someone make if they need quick results?

    1. If you need quick results, start by sealing any gaps or cracks around doors and windows with weatherstripping or caulk, since noise easily gets in through those spots. Next, add thick, dense rugs or carpets to the floor to help absorb sound. Both steps are much more effective than egg cartons or regular curtains.

  3. When you talk about creating a full soundproofing system, how important is it to combine absorption (like acoustic foam) with heavier barriers? Can I get decent results with just one or the other if my budget is tight?

    1. Combining absorption materials like acoustic foam with heavier barriers is key for effective soundproofing, as each deals with different types of noise. Acoustic foam mainly reduces echo and manages sound within the room, while barriers block outside noise. If your budget is tight, start by identifying your main issue—if it’s echoes, foam can help; if it’s blocking external noise, invest in barriers. For full results, though, both together work best.

  4. If adding a second layer of drywall is suggested for more mass, how much of a difference does that really make for blocking out conversations or loud TVs from the next room? Is it worth the effort if I just want a quieter workspace?

    1. Adding a second layer of drywall can make a noticeable difference in reducing sound transmission, especially for voices and TV noise. The extra mass helps block more sound by making the wall harder for vibrations to pass through. While it won’t create total silence, it’s generally worth the effort if you’re looking for a quieter workspace, particularly when combined with sealing gaps and using insulation.

  5. If egg cartons and thick curtains are mostly ineffective, what mistakes do people usually make when trying to soundproof their home office for the first time? Are there any common pitfalls to watch out for during the process?

    1. People often focus on blocking sound with materials like egg cartons or thick curtains, but these aren’t designed to actually reduce noise. A common mistake is neglecting small gaps around doors and windows, where sound can easily leak in or out. Another pitfall is overlooking the need for dense, airtight materials—lightweight or porous items just won’t work. It’s also important to remember that true soundproofing often requires treating both walls and floors for best results.

  6. I noticed the article emphasizes using high-density materials like mass loaded vinyl and mineral wool for better soundproofing. Is it possible to retrofit these into an existing home office without major renovations, or would installing them always involve significant wall or ceiling modifications?

    1. You can retrofit materials like mass loaded vinyl and mineral wool into an existing home office without completely tearing down walls, but some modifications are typically needed. For example, mass loaded vinyl can sometimes be added over existing drywall and covered with a new layer, while mineral wool may require removing drywall to fit it inside wall cavities. If you want minimal disruption, consider using soundproof curtains, door sweeps, or acoustic panels as alternatives.

  7. Based on your suggestions, how much of a difference can I realistically expect if I only install high-density foam panels without making major structural changes, like adding another layer of drywall?

    1. Installing high-density foam panels can noticeably reduce echoes and improve the acoustics in your home office, making it sound less hollow. However, these panels mainly absorb sound within the room rather than blocking noise from entering or leaving. If you’re dealing with loud external noises, the improvement may be limited without adding mass, like another drywall layer. For moderate noise issues and better sound quality inside the office, foam panels are a practical, non-invasive option.

  8. If I’ve already put up heavy curtains and still hear a lot of outside noise, what should be my next step? Would adding acoustic panels at specific spots be enough, or do I need to address windows and doors separately?

    1. If heavy curtains haven’t made a big difference, it’s likely that noise is getting in through gaps or thin spots like windows and doors. Acoustic panels help reduce echoes inside a room but won’t block noise coming from outside. Check your windows and doors for air gaps or thin glass, and consider sealing them or using weatherstripping. Addressing those areas will usually have a bigger impact than adding panels alone.

  9. If I already tried using thick curtains and furniture but still hear footsteps and outside sounds, which proven soundproofing technique should I prioritize next based on your recommendations?

    1. Since thick curtains and furniture haven’t solved the issue, the next most effective step is sealing gaps and cracks around doors and windows. Use weatherstripping or acoustic sealant to block sound leaks. After that, consider adding mass-loaded vinyl or installing a solid-core door, as these can significantly reduce noise transmission.

  10. You mention mass loaded vinyl as a material to block sound. For someone trying to retrofit an existing office, how complicated and time-consuming is it to install compared to just adding more drywall or foam panels?

    1. Mass loaded vinyl (MLV) is more involved to install than foam panels, but less invasive than adding an extra layer of drywall. You’ll need to cut MLV sheets to fit your walls, attach them securely (usually with nails or screws), and then seal the seams for best results. It can be done in a day for a small office, whereas new drywall requires more prep, finishing, and drying time. Foam panels are quickest, but don’t block sound as effectively as MLV.

  11. On the topic of adding mass to walls, do you have any recommendations for situations where you can’t do major construction (like in a rental)? Are there effective temporary solutions that don’t involve installing new drywall or using mass loaded vinyl permanently?

    1. If you can’t make permanent changes, you still have some solid options. Try using heavy moving blankets or thick curtains hung over your walls—they add mass and dampen sound. Bookshelves filled with books or dense furniture placed against walls can also help absorb and block noise. These solutions are temporary, effective, and easy to remove when you move out.

  12. The article says that egg cartons only diffuse high-frequency sounds a little. If footsteps from upstairs are the main issue, would mineral wool panels make a noticeable difference, or do I need to focus on something else for that kind of noise?

    1. Mineral wool panels are effective mainly for absorbing airborne noise, like voices or music, but they’re not very helpful for impact sounds such as footsteps from upstairs. To address footstep noise, you’ll want to focus on isolating or adding mass to ceilings, using solutions like resilient channels, acoustic underlay, or thicker drywall. Mineral wool might help a bit, but it’s not the main fix for impact noise.

  13. You mention that professional acoustic foam needs to be combined with other materials for a full soundproofing system. Could you elaborate on what those additional materials are and how they should be layered or installed for best results?

    1. Professional acoustic foam is effective at absorbing sound within a room but doesn’t block noise from entering or leaving. For full soundproofing, it’s best to combine it with materials like mass loaded vinyl (MLV), dense drywall, and resilient channels. Typically, you’d start by installing MLV or extra drywall to add mass to your walls, then use resilient channels to minimize vibration transfer, and finally add acoustic foam panels to control echoes inside the room. Each layer serves a distinct purpose for optimal noise isolation.

  14. I’ve already tried using thick curtains in my home office, but I still notice a lot of outside noise coming through. Do you have any suggestions for affordable next steps that don’t require major construction?

    1. If thick curtains haven’t done the trick, try adding draft stoppers or weatherstripping around doors and windows to seal gaps where sound may be entering. Bookshelves filled with books against exterior walls can also help absorb sound. Adding rugs or carpet on the floor and using acoustic panels or foam tiles are effective, budget-friendly options that don’t involve major renovations.
