Soundproofing and acoustics in 
vehicles and vessels

Sound insulation and acoustic treatment are applied to cars, buses and trucks, marine vessels, aircraft and rail transportation. The purpose of vehicle sound insulation may be to increase comfort, comply with norms or specific requirements for vehicles used as "work" vehicles.

DECIBEL has experience in silencing specialized vehicles, rail and sea vessels. The challenge in this engineering task lies in the design of a lightweight but highly efficient system with the aim of minimizing the added weight of the vehicle and achieving optimum effect at the same time. The sound insulation systems for vehicles must also comply with the relevant classes of combustibility and set standards for each type of land, sea or air transportation.

The sound insulation levels depend on the specific tasks. We at DECIBEL have achieved up to 42 dB sound insulation of a tractor with a diesel generator set for electricity used in the movie industry.
