Full Body Sound Deadening
Price: from 700 Aud
Duration: 4 days
What is included:
First Layer: Vibration damping material is applied to both the inner and outer sides of all major metal panels — including doors, floor, trunk, roof, inner arches. This drastically reduces structural resonance and body panel vibrations caused by road, engine, and suspension.
Second Layer (Optional): Sound-absorbing acoustic foam is installed over the first layer in key cabin zones. It reduces airborne noise such as tire hum, wind, and engine roar — making conversations clearer and highway driving more relaxed.
Maximum Effect: This is our most complete package — delivering luxury-level cabin comfort. It ensures the highest possible reduction in road noise, significantly enhances speaker performance, and adds thermal insulation benefits. You’ll feel the difference from the very first drive.

What problems we solve
Noise & Vibration Protection
We apply multi-layer sound deadening treatments that eliminate road noise, creaks, and low-frequency hums. This protects your health and patience—especially on long drives.
Improved Sound System Performance
By reducing structural vibrations in the car body using vibration-damping materials, we create an acoustically optimized space. Foamed sound absorbers help capture and scatter sound waves, enhancing clarity and depth of your audio system.
Thermal Insulation
We use specialized materials with heat-insulating properties to treat the vehicle. This helps keep the cabin warmer in winter and cooler in summer, improving overall driving comfort.
Better Road Stability
Proper sound deadening improves driving feel. The car becomes more stable in turns, and vibrations from passing traffic are significantly reduced—resulting in a smoother, more controlled ride.
Corrosion Protection
We use materials with anti-corrosion and sealing properties to add long-term protection to your vehicle's body panels and cavities.
Body Reinforcement
Our treatments help increase the rigidity of the car body, reducing flex and enhancing the vehicle’s structural integrity.

Yes, we do offer mobile service — provided that your space is clean, well-lit, dry, and warm (especially in winter).
We can, but a sound level meter and decibel readings don’t reflect the perceived difference accurately. Decibels are a logarithmic unit — a 3 dB change (from 46 dB to 43 dB) means the noise level is cut in half, and a 6 dB change means it’s reduced by four times.
In all our experience — and the experience of the manufacturer Shumoff — we’ve never encountered a single case of door sagging caused by sound deadening, as long as the materials were properly selected for the vehicle.
If the metal surface is properly cleaned and the vibration-damping material is firmly applied, it can actually act as an anti-corrosion layer.
- Corrosion under sound deadening only happens when the surface isn’t prepared correctly or the installation process is done improperly.
