2.1 The Measurement of Noise on Agricultural Machinery
with Human Staff
The noise level measurement was done using an 80 hp New Holland TD80D tractor,
aggregated with the miscanthus planting machine and the forest seedlings planting
machine. Figure 5 shows four images of the noise measurement activity in the neighbourhood of the tractor. Also, in Fig. 5, it shows the position of the referential system
fixed to the tractor (do with the machine). The background noise level was 53.2 dB.
