Automotive and vehicle interior sound insulation consists of custom-cut acoustic components designed to prevent engine, tyre and aerodynamic noise from being transmitted into the cabin in passenger cars, commercial vehicles and special projects. Door felt, engine-bay insulation, panel damper and roof fill are combined. All products are compliant with FMVSS 302 / EN 45545-2 automotive fire tests.
What is automotive acoustics?
Automotive acoustics is the engineering discipline that optimises the total noise and vibration experience felt by occupants inside a vehicle. It is known as NVH (Noise, Vibration, Harshness). Premium vehicles invest seriously in this; aftermarket also has high demand for upgrades.
Which vehicle types?
- Passenger car (premium-model upgrades)
- Commercial vehicle (panel van, minibus, bus)
- Caravan / motorhome
- Special vehicle projects (armoured, ambulance)
- Truck / lorry cabin
- Construction-machine cabin
Solution components
- Panel damper (CLD): bituminous sheet reducing sheet-panel vibration
- Door felt: custom-cut sealing
- Roof fill: absorbent felt + aluminium barrier
- Engine-bay insulation: high-temperature-resistant composite
- Floor sound and heat barrier: laminated composite
- Wheel-arch barrier: tyre-noise control
Certification requirements
- FMVSS 302 (American automotive fire)
- EN 45545-2 (European rail-vehicle fire)
- RoHS / REACH (chemical compliance)
- OEM-specific test procedures
Target performance
- Cabin dB reduction: 5-10 dBA
- Engine bay-to-cabin transition: -25 dB
- Tyre / road noise reduction: -15 dB
- Fire resistance: FMVSS 302 compliant
Lead time and cost
Aftermarket passenger-car upgrade 1-3 days. Commercial-vehicle project 1-2 weeks. OEM serial-production product development 3-6 months.
