Frequently Asked Questions
What is car soundproofing?
Car soundproofing involves adding specialist acoustic materials to areas such as doors, boot, floor, and arches to reduce road noise, vibration, and rattles, improving overall cabin comfort.
What benefits will soundproofing give me?
Soundproofing results in a quieter cabin, clearer audio, improved bass response, and reduced road and tyre noise, making long journeys more comfortable and music sound better.
Will soundproofing make a noticeable difference?
Yes. Most customers notice a significant reduction in noise and vibration, especially at motorway speeds, along with improved speaker performance.
Will soundproofing add a lot of weight to my car?
No. We use modern lightweight sound-deadening materials, adding minimal weight while delivering maximum noise reduction.
