Recent researches [1, 2, 3 and 4] showed that the vibration is one of the common occupational risks. The exposition rising to the human body vibration, in hard working that operate tractors, machines diggers and too much vehicles is incomplete, however there are evidences that the regular exhibition to the vibration, can contribute in the pains generation in the back in professional drivers such as, drivers by bus, by tractors and helicopters. According to Griffin [2], to the exhibition to the human body vibration are related to problems in the activity muscular/postural, circulatory system problems and the appearance of inter-muscular disturbances. This way, with the increasing use of off-road vehicles and of new kinds of seats, the acceleration levels investigation and necessary comfort is done, as well as, the dynamic characterization of the same. Using the prototype of a mini Baja, usually used in competitions, the level of vertical accelerations to what a stature median pilot is submitted, it was characterized when the vehicle rolling on a plane track category. The acquired data allow evaluating the exhibition to the original vibrations of the vehicle, contributing for vehicles companies manufacturers. In terms of noise it seeks to accomplish an evaluation of the emitted noise and spectrum. The obtained data of sound level will be analyzed statistically in the attempt to extract useful information, how to identify the levels and the frequencies that affect most the human beings.
