Title Evaluation of noise levels caused by different groups of mechanical equipment
Original title Avaliação do nível de ruído causado por diferentes conjuntos mecanizados [in Portuguese]

Abstract The purpose of this study was to evaluate the noise levels emitted by various agricultural machines in order to determine the risks faced by operators during work in the fields. The equipment evaluated included a tractor coupled to a plough, a grader, a liquid manure spreader and a sower, as well as a harvester. Trials were carried out with the tractor coupled to each of these devices while being driven at different speeds with the engine turning at 1700 rpm. The harvester was also tested at different speeds. Noise levels recorded to the left and right of the operator were very high and exceeded permissible levels. The noise generated by the equipment was unpleasant to the operator, the most unpleasant being that generated by the harvester. The noise levels of the tractor and harvester engines at standstill were also very high and presented a risk not only to the operator but also to persons situated near the machines.
