Toyota Rav4. Full Body Sound Deadening.
I was initially skeptical about whether sound deadening would work or be worth the investment. But after having it done on my car, the difference is incredible. The road noise has been significantly reduced and the sound system sounds much better than before. No more rattles or road noise. The car is now very quiet, even over speed bumps and potholes. It also feels heavier and more solid, which has noticeably improved the handling. Dimitry did the job very professionally and I’m really happy with the whole experience. This is definitely a must-do modification!

Audi A4. 4 Doors
I soundproofed all four doors, and I’m completely satisfied. All the noise is gone, and now the car feels as new as it did on the first day of delivery.

Yaris GR. 2 Doors, Boot lid.
Just had the front doors of my GR Yaris soundproofed by Dimitriy at Car Sound Deadening Solutions — and what an incredible job! He’s meticulous, uses premium materials, and the difference is night and day. My upgraded speakers now sound even better, outside noise is drastically reduced, and the car feels far more refined — almost like a high-end vehicle. Truly exceeded my expectations. Highly recommended, and I’ll definitely be back to get more work done on the rest of the car.

Mitsubishi ASX. Full Body Sound Deadening.
Loved my experience with Dimitri and his car sound deadening service. He's very passionate about his work and I really appreciated how his advice and suggestions had my best interests in mind instead of any unnecessary upselling. 100% recommend contacting him for any car sound deadening needs.

Subaru Impreza WRX. 4 Doors.
Dimitri soundproofed the doors on my WRX. I was very surprised by the difference. I knew it would be more quiet but not to the extend of how much better it was inside. He also told me the speaker quality would sound better which I was semi skeptical of but he absolutely did not lie. The speakers sounded significantly better and the bass and sound depth was a massive improvement. Highly recommend. Great job and very knowledgeable about his work

FAQ

1. Shipping & Delivery

Shipping costs are calculated at checkout based on the weight of your order and your location.

  • VIC, NSW, SA, QLD (Metro): 2–5 business days.
  • WA, TAS, NT & Regional Areas: 5–10 business days.
  • Please note regarding rural areas: Deliveries to remote locations may take slightly longer due to courier schedules.

We use trusted carrier - Direct Freight Express to ensure your sound deadening materials arrive safely. You will receive a tracking number as soon as your order is dispatched.

2. Product & Technical

Our butyl-based sound deadener is designed to withstand extreme temperatures. It will not melt, drip, or smell, even during the hottest Australian summer days. It is engineered for high heat resistance.

We have datasheets on all materials:

It depends on your vehicle size (Ute, Sedan, SUV, or 4WD) and coverage area.

  • Doors: Typically 1.5–2 sq/m per pair of doors.
  • Floor: Approx. 3–4 sq/m for a standard sedan.
  • Full Interior: Usually requires 10–14 sq/m.
  • Tip: Check our product descriptions for specific "Packs" tailored to different vehicle sizes.

In most cases, yes — using both layers gives the best result.

The first layer (vibration damping) stops the metal and plastic panels from vibrating. Without this step, panels can still rattle and amplify noise, even if insulation is added on top.

The second layer (sound absorption or sound blocking) works on airborne noise — road noise, tyre noise, wind noise, and engine sound. It absorbs or blocks sound that would otherwise pass straight into the cabin.

If you use only the second layer, vibrations may remain.
If you use only the first layer, some noise will still get through.

When both layers are combined, they work together to deliver a quieter, more comfortable, and more solid-feeling cabin — especially for long drives, family trips, or vans used for camping.

For some small or budget-focused projects, one layer may still help, but we always recommend combining layers where possible for the best long-term result.

No — when done correctly, the added weight is minimal.

For 2 doors, sound deadening typically adds around 5–6 kg. We use lightweight, premium STP materials designed to deliver maximum noise reduction without unnecessary mass.

A full body soundproofing setup usually adds around 50 kg in total, which is less than the weight of one adult passenger or a full tank of fuel. This amount of weight has a negligible impact on fuel economy, handling, or performance — especially compared to the comfort gained.

The key is using the right materials in the right places, not overloading the car. That’s exactly how we approach every build.

3. Installation

Our products are designed to be DIY-friendly and easy to install. They use a peel-and-stick adhesive backing, so no special skills are required.

We provide detailed written instructions and clear guidance for each material, explaining exactly where and how it should be installed. By following these instructions — or using our step-by-step videos — you can confidently install the right solution in your own garage over a weekend.

Professional installation is always available if you prefer, but many of our customers successfully complete their own soundproofing projects using our instructions and support.

You only need a few basic tools:

  1. A Application Roller (crucial for ensuring proper adhesion).
  2. A sharp utility knife or heavy-duty scissors.
  3. Cleaning alcohol and a rag (to clean the metal surface before applying).
  • Make sure to add a roller to your cart if you don't have one!

4. Returns & Warranty

Yes, we accept returns on unopened and undamaged boxes within 30 days of purchase. Please note that return shipping costs are the responsibility of the customer.

Yes, all our sound deadening materials come with a warranty against manufacturing defects, ensuring they won't peel or degrade over time.
