Why Sound Deaden Your Vehicle?
Professional sound deadening significantly reduces unwanted noise and improves overall driving comfort. Based in Bromsgrove, Ultimate Audio provides expert sound deadening solutions for vans, campervans, and cars, helping create a quieter, more refined interior environment.
Sound deadening can:
Reduce road, engine, wind, and speaker vibration noise
Improve interior acoustics for music and conversation
Enhance comfort for both driving and living spaces
Our Proven 3-Stage Sound Deadening Process
To effectively make a vehicle quieter and more comfortable, we use a proven three-stage sound deadening process, tailored to each vehicle and application.
Step 1: Vibration Control (Sound Deadening Mat)
The first stage involves applying a sound deadening mat directly to exposed metal panels throughout the vehicle. Vibrations caused by the engine, tyres, speakers, and road surface cause metal panels to resonate and amplify unwanted noise inside the cabin.
By applying a sound deadening mat, these vibrations are dampened at the source, immediately reducing overall noise levels. These mats are typically manufactured using a high-density mastic adhesive combined with an aluminium foil layer and are available in various thicknesses to suit different areas of the vehicle and performance requirements.
Step 2: Sound Isolation (Multi-Layer Barrier Materials)
The second stage focuses on blocking and isolating noise before it enters the cabin. This involves installing a dense sound isolation layer designed to stop sound waves passing through the vehicle structure.
For this, we typically use Comfort Mat Blockshot, an 8mm multi-layer barrier material capable of blocking up to 80% of unwanted noise, or 6mm Integra Space, depending on space and application requirements. These materials are commonly installed on the cabin floor, bulkhead, and boot floor once the metal panels have been treated with sound deadening matting.
Step 3: Airborne Noise Absorption (Foams & Wave Diffusers)
The final stage involves absorbing any remaining airborne noise that travels through doors, floors, and roof panels. We use a range of high-quality foam-based acoustic materials, including:
Closed-cell foam, which provides excellent thermal insulation alongside effective acoustic absorption
Wave diffusers, which can absorb up to 40% more sound than flat materials
Foam materials also help eliminate rattles and squeaks from plastic trims and panels, further improving refinement.
Wave diffusers and foam linings are highly effective sound-absorbing and sealing materials. Their wavy surface, combined with an open-cell microporous elastic structure and high density, allows for excellent noise absorption across a wide frequency range. The material’s shape-memory and flexibility enable installation even in tight or irregular spaces.
