摘要：This paper analyzes the magnitude of the acoustic pressure contribution of a combine harvester’s thresher drum to the overall noise situation with the goal of providing the regulatory parameters for the workplace conditions. In the course of the current research the velocity and pressure graphics for the airflow on the parts of a rotating thresher drum as well as the sound intensity parameters by frequency spectra and sound pressure magnitudes were calculated.
