Determination of the effectes of tractor cabins in different structures on noise isolation

In this research, noise pressure levels were evaluated among tractors, which are the power machines that play an important role in agricaltural mechanization. Measurements were performed with Brüel&Kjaer 2250 type sound levelmeter. During measurement, noise level values were analyzed.The aim of this study is to determine the noise level spreading throughout the environment during aricultural processes in which tractors are used and to determine the effects of tractor cabin features with different structures on the internal cabin isolation.Consequently, varying result were obtained for he noise pressure levels in the experiments performed with tractors having different cabin features in sationary state at 540 r/min. The noise pressure reaches levels that can threaten the driver?s health. Some psychological and psychological helath problems may also ocur when working time is increased.
