Acoustic conditions on self-propelled forage harvesters

Stanek, J.; Siska, J.

Zemedelska Technika 25(4): 225-237


The sound levels with the A weighting and the power spectra of the vibrations were recorded in the driver's cab of 4 different models of self-propelled forage harvester with the machine at rest and in operation, and the engine idling, running at its rated speed or at high speed, with the door open or closed. The noise emission was measured at distances of 3 and 10 m from the machine, to either side, the front and rear.
