Noise Reduction in the Cab of a Special Vehicle

Noise is highly associated with adverse effects on health, the human psyche and performance. Current special vehicles do not possess sufficient technologies to suppress transmission of noise or vibration, which typically results in loss control, comfort, driving safety, performance tasks, etc. At same time, reduces attention work efficiency while increasing fatigue, leading hazards, dangerous situations, missions that may be completed. This article briefly presents selected parts a project included additional soundproofing armoured mobile vehicle TATRA wheeled chassis. Basic theoretical, experimental, practical information about this presented. To reduce noise, damping material was used, combination recycled PUR foam black rubber rough structure. The based repeated experimental testing sound absorption measurements from several materials. chosen for suitable corresponding technological properties (resistance high temperatures, non-flammability, etc.). In engine compartment cab vehicle, were experimentally verified after retrofitting, significantly reduced.
