Abstract
The acoustic emission of rotary drilling rigs consists of the partial sound sources of the diesel engine, the fans of the cooling system and the rotary drive. Usually, the machines are acoustically characterised according to the outdoor noise directive 2000/14/EC with a value for the averaged sound power. However, the subjective noise exposure for construction site employees can differ from the measured sound power level depending on their location on the construction site. In our test setup, we examine the acoustic emission of the device from the perspective of the construction site workers, once from the machine operator in the operator’s cab and once from the site assistant giving instructions outside. Using artificial head measurements, we analyse the psychoacoustic parameters of loudness, sharpness, roughness and tonality at different operating points of the drilling rig. It turns out that, despite similar values for the sound power, the psychoacoustic parameters can characterise the sound radiation of the drilling rig in a more differentiated way at specific operating points.
