| Abstract: |
| The sound produced by combines is one of the main sources of sound production in agricultural machines. The noise produced can cause irreparable damage to the drivers of agricultural machines; Therefore, it is necessary to determine the level of noise annoyance on such people and to take measures to reduce it. In this research, the signals of Sempo combine model 3065 and Jandeer combine model 1055 were used. The main factors were the position of the microphone and the type of operation in three repetitions. In order to evaluate subjective data, a jury test was used. The results showed that in the Sampo combine, the main factors mentioned on the average sound annoyance are 24.16% in free movement conditions and 63.00% during harvesting. Also, in the position of the microphone next to the driver's ear inside the cabin, the average sound annoyance was 58.51% and outside the cabin was 74.89% in Jandir combine. |
