Learn how to block, absorb, and isolate sound using proven soundproofing methods for studios, home offices, bedrooms, and more.
Soundproofing a room involves four key methods: blocking sound with mass, absorbing sound with fibrous materials, dampening vibrations, and decoupling structural elements. The right approach depends on your room type, budget, and the level of sound reduction needed.
To block outside noise, focus on sealing gaps around windows and doors, installing double-glazed windows, adding Mass Loaded Vinyl to walls, and using heavy curtains. For maximum effect, fill wall cavities with acoustic insulation and add an extra layer of acoustic plasterboard.
Budget-friendly options include adding heavy curtains, placing rugs on hard floors, using draft snakes under doors, mounting acoustic foam panels on walls, and sealing gaps with weather stripping. These won't provide studio-grade isolation but will noticeably reduce noise.
How Sound Travels
Sound waves lose energy as they pass through mass. Adding more layers reduces transmission significantly.

The answers depend on the room's purpose and the type of sound you're dealing with.
Start by asking yourself: do I need to stop sound entering or leaving the room, control sound within it, or both? Then determine whether you're dealing with airborne sound, impact sound, or both.
Regardless of your goal, you'll need to employ one or more of the four basic soundproofing methods shown here. Knowing which to use will determine which products you need.oms, and more.
Sound Blocking
Adding mass to walls, floors or ceilings to stop sound from traveling through the structure.
Sound Absorption
Using fibrous materials to absorb and control sound energy within the space.
Sound Dampening
Reducing vibrational energy of soundwaves to prevent them from traveling through structures.
Sound Decoupling
Isolating construction elements to prevent sound waves from traveling between them.
You can soundproof any room, but some benefit more than others. We start with the most complex.
Recording Studios
Room-within-room for isolation.
MLV, Acoustic Batts, Resilient Clips
Home Theater
Solid, non-vibrating walls for immersive sound.
Acoustic Insulation, MLV, Plasterboard
Home Office
Block distractions for focus and productivity.
Acoustic Panels, Insulation Batts
Bedrooms
Peaceful rest and undisturbed sleep.
Soundbreak 90mm Batts
Bathrooms
Privacy and reduced plumbing noise.
Acoustic Batts, Pipe Lagging
Laundry Rooms
Eliminate washer and dryer vibration noise.
Acoustic Insulation, Anti-vibration
Recording studios require the highest level of soundproofing. Ideally, you'd build a "room within a room" — a fully decoupled inner structure that prevents virtually all sound transfer.
Both rooms are typically constructed from timber frames, lined with high-density acoustic batts, Mass Loaded Vinyl, and acoustic plasterboard. All gaps around doors, windows, and electrical fittings are sealed to prevent sound leakage.
Recommended Materials
Mass Loaded Vinyl
Acoustic Batts (Polyester, Rockwool, or Glasswool)
Heavy-density Acoustic Plasterboard
Resilient Mount Clips
Needle-punched Polyester Acoustic Panels
Acoustic Sealant for gaps
Unlike studios, a home theater usually doesn't need a "room within a room." Instead, focus on creating solid walls that don't vibrate. These walls should include:
Recommended Materials
1 Heavy-density acoustic insulation inside walls to absorb sound
2 Mass Loaded Vinyl or similar heavy dampening material layer
3 Acoustic plasterboard for additional mass
4 Resilient mount clips to decouple plasterboard from studs
Using resilient mount clips creates a vibration break between the plasterboard and studs, further reducing sound transmission significantly.
Working from home requires a quiet sanctuary free from distractions. Proper soundproofing can make a BIG difference, helping you stay focused and productive throughout the day.
It works both ways — it prevents your calls and conversations from disturbing the family, while keeping household noise out of your workspace.
Common Noise Sources:
Kids
Lawnmower
Street Noise
Neighbours
Adding acoustic insulation during construction costs little compared to the total home budget and provides lasting comfort for years.
Bedrooms
Your bedroom should be tranquil and restful. The minimum we recommend is a high-quality acoustic insulation batt within the walls — the Soundbreak 90mm Batts are ideal for creating a peaceful sleeping environment.
Bathrooms
Privacy is the obvious benefit. Using acoustic insulation batts within walls is a must. For bathrooms, we highly recommend Nuwrap5 Pipe Lagging to silence flushing and shower sounds that disturb adjacent rooms.
Laundry Rooms
Noisy washing machines and dryers are all too familiar. Soundproofing eliminates spinning, whirring, banging, and beeping noises to ensure peace and quiet throughout the home.

The best time to soundproof is during construction, but don't despair if your home is already built. Depending on your budget and requirements, follow these steps:
Common Noise Sources:
Step 1: Add Soft Furnishings
Heavy curtains, carpets, and rugs to reduce sound bouncing in open-plan spaces.
Step 2: Install Acoustic Panels
Mount decorative sound-absorbing tiles on walls and ceilings — strategically placed for maximum effect.
Step 3: Add Mass Loaded Vinyl
Apply MLV to existing walls. This high-density, thin, flexible vinyl sheet significantly reduces sound transfer.
Step 4: Add Acoustic Plasterboard
Install an additional layer of acoustic plasterboard over the MLV for approximately 80% sound reduction.
Step 5: Fill Wall Cavities
For loud rooms, remove plasterboard, fill cavities with fibreglass, polyester, or rockwool insulation, then reinstall on resilient mounts.
You can soundproof any room, but some benefit more than others. We start with the most complex.
Recording Studios
Don't forget to soundproof floors and ceilings as well as walls for complete room isolation.
Solid Core Doors
Modern hollow doors are terrible for blocking sound. Replace with solid core doors or add MLV to existing ones.
Seal All Gaps
Use door sweeps and weather stripping. A door sweep falls into place when closed, sealing the gap automatically.
Double Glazed Windows
Install double-glazed windows for maximum sound and heat blocking. They make a significant difference.
Secondary Glazing
If replacing windows isn't an option, install a second window 50mm behind the original for a double-glazed effect.
