Acoustic Dampening Treatment for Sprinter & Transit Vans

Precision-Controlled Cabin Quieting for High-Fidelity Travel

Engineered for: Mercedes Sprinter, Ford Transit, Winnebago Revel, Winnebago Ekko, Tiffin GH1/GH2, and Tiffin Open Trail.

A van is an extraordinary travel platform but acoustically, it is a difficult space. Thin metal panels, large flat surfaces, and minimal insulation create a constant undercurrent of mechanical noise and vibration. This environment masks clarity, reduces comfort, and prevents even the best audio systems from performing as intended.

Our acoustic dampening treatment is designed to correct these inherent limitations at the structural level.

The Experience: A Quieter, Calmer, More Refined Cabin

Our protocol targets three primary acoustic intrusions:

• Structure-Borne Vibration
• The shaking and flexing of metal panels that create unwanted resonance and “buzz.”
• Road Noise Intrusion
• Tire, wind, and surface noise entering through the cab floor and door cavities.
• Acoustic Masking

By treating the cab floor and front doors with engineered damping materials, we reduce resonance at the source and lower the noise floor of the entire cabin.

What You Will Notice Immediately

Lower Noise Floor
The cabin quiets. Subtle details emerge. Conversations become easier. Music becomes more intelligible at lower volume.

Reduced Resonance & Panel Buzz
Door skins and floor panels become structurally stable, eliminating vibration that often accompanies bumps, engine load, or bass response.

Improved Perceived Power in Your Audio System
With less noise competing for attention, the existing speakers — or upgraded ones — sound clearer, stronger, and more defined.

Enhanced Long-Distance Comfort
A calmer cabin reduces cognitive fatigue during multi-hour drives.

The Engineering: Material Science Meets Acoustics

We do not use off-the-shelf insulation rolls or lightweight hobby materials.
We use automotive-grade composite dampers that bond to metal and convert vibrational energy into heat, neutralizing resonance instead of merely covering it.

Two Thickness Options Available

Standard Dampening Layer (Approx. 80 mil)
• Ideal for van owners seeking refinement without adding significant mass
• Excellent for reducing mid-frequency vibration in doors
• A balanced choice for daily drivers and long-distance touring

Advanced Hybrid Dampening Layer (Approx. 200 mil)
• A multi-layer, thermally bonded composite
• Optimized for high-intensity resonance in cab floors and door panels
• Provides the most noticeable drop in perceived road noise
• Ideal for owners pairing this treatment with an audio upgrade

Both materials undergo the same installation protocol. The difference is simply the degree of vibration isolation desired.

Installation Protocol

Every van receives a controlled, methodical application:

1. Full Panel Preparation

Panels are cleaned, decontaminated, and prepped to ensure a chemical bond between metal and damping layer.

2. Strategic Acoustic Mapping

We identify resonance-prone zones in the doors and cab floor using a combination of empirical testing and known chassis patterns.

3. Precision Material Application

Damping layers are cut, rolled, and pressure-set to ensure long-term adhesion and maximum vibration conversion.

4. Reassembly Without Compromise

All factory clips, vapor barriers, and hardware are reinstalled exactly to OEM specification. Nothing rattles. Nothing is forced. Nothing is improvised.

Why This Matters for Audio Performance

Even a premium audio system struggles in a noisy cabin. Dampening creates a cleaner acoustic foundation so high-quality speakers, subwoofers, and amplifiers can perform with accuracy and depth.

This is why our dampening treatment is often chosen:

• before an audio upgrade,
• alongside a speaker upgrade, or
• as part of our Integrated Audio System.

A quieter cabin is the first step to a higher-fidelity vehicle.
