Noise pollutants in agricultural machinery drivers cabin

Abstract

Agricultural machineries are among those having the negative features with high noise emissions, especially in the vicinity of operation routes and the driver's cabin. An option for reducing this load, at the first place, is the necessity to specify the source of the noise. The main sources belong to rolling noise and the noise of the drive power of the farm machineries, significantly, the noise of vehicle propulsion. To these important resources, it is necessary to add secondary noise sources such as concomitantly induced noise from the brakes, operational velocity, frequent stop and kick-off, safety equipment, local radio, etc. The size of these adverse effects also depends on the type of the traction, route guidance, features of the terrain, technical conditions of vehicles and transport routes. In this research paper, the authors examine the noise pollutants appearing in the drivers' cabin during their performance through careful measurements. The research was conducted on combine harvesters and tractors. The core finding of this research is the presumption of the cause of the changes in noise pollutants based on the collected data.
