Streszczenie: The paper explores the influence of noise within the cabin of an agricultural tractor on the health of the operator during the operation of a semi-trailed fruit tree shaker. The research aims to determine the noise levels at various rotations of the power take-off shaft during the mentioned agro-technical operation and assess the potential negative impact on the operator's health. Noise measurements were conducted on agricultural fields at the Barica Sabo Family Farm using two tractor models (John Deere 6110 MC and Hurlimann XT-910.4) in accordance with the prescribed standards HRN ISO 6394 and HRN ISO 5131. Measurements were taken on both the left and right sides of the operator in both tractor cabins under operational conditions, using equipment provided by Metrel, specifically the Multinorm MI 6201 EU device with the corresponding sound probe (Class B microphone). The highest equivalent continuous A-weighted sound level (LAeq) was measured during the operation of the power take-off shaft at 500 rpm for both tractors on the right side (John Deere, 76.7 dB) and the left side (Hurlimann, 77.2 dB). Furthermore, the highest time-averaged maximum sound level (LAFmax) was measured on the left side of the Hurlimann tractor at 79.7 dB at 500 rpm. It was determined that the measured noise levels did not exceed the permissible exposure limit values: L(EX,8h) = 87 dB(A), upper cautionary exposure limits: L(EX,8h) = 85 dB(A) and lower cautionary exposure limits: L(EX,8h) = 80 dB(A). Although the highest measured value (79.7 dB) is close to the lower cautionary limit (80 dB), it is assumed that the operator of the investigated tractors is not exposed to negative noise-related health effects.
