Soundproof and reduce noise in wheel arches in a vehicle – for a quieter and more comfortable driving experience
Road noise is one of the most common sources of noise in a vehicle, and the wheel arches are among the biggest contributing factors. The wheel arches are located close to the tires and the road surface, which means that vibrations and noise from the ground are transmitted into the vehicle cabin. By soundproofing the wheel arches, you can significantly reduce disturbing road noise and create a quieter and more pleasant driving experience.
Why soundproof the wheel arches?
When the car travels over different road surfaces, noise is generated from the tires' contact with asphalt, gravel, or uneven surfaces. This noise propagates through the wheel arches and into the cabin, which can affect both comfort and driving pleasure.
Common problems that can be solved by soundproofing the wheel arches:
Reduced tire noise
Rough road surfaces, studded tires, and low-profile tires can create high rolling resistance and thus a higher noise level in the cabin.
Dampened vibrations
Shocks and irregularities from the road can be amplified through the wheel arches and spread further through the vehicle’s chassis.
Increased driving comfort
A quieter cabin provides a more relaxed driving experience and makes it easier to have conversations or listen to music without disturbances.
Which vehicles benefit most from wheel arch insulation?
All cars can benefit from improved soundproofing, but some types of vehicles have more issues with road noise than others:
Electric cars and hybrids
Since these vehicles lack engine noise, tire and road noise become more prominent.
SUVs and vans
Larger wheels and higher ground clearance allow more noise to enter the cabin.
Older cars
Many older models have poorer soundproofing compared to modern vehicles.
Cars with low-profile tires
Sportier tires with thinner sidewalls can generate more road noise than traditional tires.
How much can wheel arch soundproofing reduce the noise level?
Effective soundproofing can reduce road noise in the cabin by 3–8 decibels, depending on the road surface, tire type, and the vehicle’s original soundproofing. The greatest improvement is noticeable at higher speeds and on rough roads, where the noise can otherwise be very intrusive.
Soundproofing the wheel arches is a relatively simple measure that can make a big difference in the driving experience. With the right method and materials, you can create a quieter, more comfortable, and enjoyable ride – no matter the road conditions.
