Abstract
One of the most important parameters determining the operational quality of farm tractors and sales results is the noise level in the cab. In this study the level of noise to which the operator in the cab is exposed and which negatively affects their psychophysical condition was measured and analysed. Tractor manufacturers in Europe and on other continents have effectively reduced the noise level generated by their products. None of 385 models of 20 brands exceeded the noise limit of 115 dB(A) set by the Polish law. However, there were models where the daily 8 hour noise exposure level exceeded 85 dB(A). Our research showed that this parameter still needs to be improved.
