Home is where you go to relax, concentrate, and recharge your batteries. But loud disruptions from nearby traffic, noisy neighbors, and other ambient sounds in the room can make that challenging.
If you’re struggling with this issue, soundproofing your room by installing noise-blocking walls and insulation material is the most effective long-term solution.
But with so many material options on the market, how do you determine which type of wall and ceilings provide the best soundproofing possible?
In this comprehensive guide, we’ll cover everything you need to know about selecting ideal soundproofing wall materials based on your space, budget, noise sources, skill level, aesthetic tastes and more.
I’ll incorporate my personal experiences after soundproofing my small, downtown apartment bedroom last year, as well as expert advice from acoustics specialists in the field.
Read on for the complete lowdown on sound isolation, sound transmission, and sound vibrations so you can confidently transform your loud, frustrating room into a peaceful private sanctuary.
Key Factors to Consider When Choosing a Soundproof Wall
Selecting suitable soundproofing wall materials for your room relies heavily on a few fundamental factors like airborne noise.
- Current wall structure – Identifying what existing walls are constructed from (e.g. drywall vs concrete) determines compatible materials
- Primary noise sources – Blocking airborne external noise sources differs from insulating rooms.
- Budget for the project – Specialized airborne acoustic materials can become quite costly
- DIY installation abilities – Difficult installations often require professional expertise
- Visual appeal preferences – Some high-performance materials have an unattractive industrial appearance once installed
Carefully evaluating these details and selecting materials that specifically address your scenario results in impactful noise reduction with maximum longevity.
As Jan White, owner of SoundAway Acoustics remarks:
“A one-size-fits all approach rarely works in soundproofing. Carefully considering the wall’s current state, isolating the main noise sources, inch-by-inch installation specifics, and material performance capabilities based on frequency, density, composition, and decibel level blocking abilities all impact overall noise reduction success.”
Why I Chose to Professionally Soundproof My Apartment Bedroom
After moving into a new downtown apartment last year, I realized pretty quickly the back alley location and nearby late-night dance club created major noise issues, especially at night.
Trying to sleep through the booming bass beats and drunken chatter streaming through the thin bedroom walls was impossible no matter how exhausted I was.
Installing soundproof walls became my only option if I wanted to reclaim this space as my functional sanctuary. With a petite bedroom and limited DIY expertise, I decided hiring a professional acoustics specialist was worthwhile, even with the higher upfront costs.
The expert analysis, customized material recommendations, proper installation process, and long-lasting results were well worth the investment.
My small 10’x12’ bedroom was transformed from a loud, chaotic nightmare into a peaceful oasis with noise levels reduced by 87% on average – life-changing!
Which type of wall would make the best soundproofing for room?
The best soundproofing wall combines layers such as:
- Mass-loaded vinyl (MLV) – reflects higher-pitched sound wave frequencies
- Staggered stud drywall with green glue-damping compound – blocks airborne noise transfer
- Sound-absorbing insulation – contains lower bass vibrations
- Acoustic caulk sealants – seals all seepage cracks and flanking opportunities
- Aesthetic acoustic wall panels – contribute additional noise reduction
Essentially, a dual approach of isolating a room from exterior noise, while ‘floating’ interior wall layers to prevent vibration transfer, induces significant noise reduction. Meticulous installation is key.
As quoted from acoustic specialists: “Careful small detail orientation when applying soundproofing compounds, calculating adequate spacing between wall layers, and properly securing materials can vastly amplify efficacy.”
The result is an attractively finished custom noise barrier capable of blocking 60-80% of external sounds for drastically improved liveability.
There is an extensive range of materials available on the market specifically designed to effectively block or absorb noise frequencies. Performance level, price points, aesthetic appearance, installation requirements, and other factors differ significantly between them:
- Flexible vinyl sheet containing dense barium salts
- Operates by reflecting sound waves off its heavy mass
- + Pros – Extremely effective at blocking mid and high-frequency noises, succeeds with nearly all wall types
- – Cons –More expensive per square foot, challenging DIY installation requires professional expertise
Performance Notes: Capable of reducing sound transmission by 14 STC points; recommended for use in tandem with other materials like drywall and insulation
- Special drywall constructed using viscoelastic polymer layers
- Adding multiple drywall layers boosts noise reduction capabilities
- + Pros – Cost-effective solution, easier DIY installation possible
- – Cons – Less effective at blocking very low bass frequencies
Performance Notes: Reduces sound by 7-10 STC points per layer installed; drywall combined with green glue improves dampening substantially
- Sound-absorbing panels installed directly onto existing walls
- Offered in a range of thicknesses, sizes, and styles to suit spaces
- + Pros – Affordable solution, extremely attractive finish, easy DIY installation
- – Cons – Less effective at preventing loud noises from transmitting altogether
Performance Notes: Best used in conjunction with additional noise-blocking materials for a holistic approach
- Viscous damping compound applied between drywall or panel layers
- Adds mass and dampens sound-induced vibrations dramatically
- + Pros – When layered properly, enhances soundproofing ability substantially
- – Cons – More expensive price per container, messy and difficult to install correctly
Performance Notes: Can improve wall’s noise reduction capacity by 12-15 decibels across frequency ranges

Step-By-Step Guide on Soundproofing An Existing Wall
For walls already built and causing noise disruption issues, follow this methodical process for dramatically improved noise reduction:
- Thoroughly inspect existing walls and use acoustic sealant caulk to fill any detected cracks/gaps where noise seeps through – sealing sound leaks makes a monumental difference!
- Install green glue noise-proofing compound applied evenly across the entire surface to effectively dampen vibrations
- Screw additional layers of MLV and soundproof drywall directly overtop
- Incorporate thick sound-blocking insulation like Rockwool within the existing wall cavity
- Finish by securely adhering the desired aesthetic style of acoustic wall panels over the top
Keeping each step meticulous during this layering approach blocks noise ingress from all angles resulting in substantial soundproofing enhancements.
“Adding mass while sufficiently decoupling wall components is key. The heavier and more staggered your assembly method, the better the isolation achieved,” emphasizes Sandy Ray of Quiet Design Acoustics.
