“…Productivity in agricultural operations depends not only on the machinery employed, but on the health and well-being of the operator and auxiliary workers (SILVA et al, 2004;GOMES et al, 2021). Thus, it is essential to identify the working conditions that generate higher noise levels, and the influence of engine power, year of manufacture, presence of cabin, and activation of implements (BAESSO et al, 2017;GOMES et al, 2021).…”

“…Older tractors, due to the materials used in their components and ergonomic deprivation, emit higher noise levels and, for the most part, do not have a cab for acoustic insulation (MION et al, 2009;BAESSO et al, 2017;CHAIBEN NETO et al, 2020;GOMES et al, 2021). The absence of a cabin causes an increase of approximately 15 dB(A) in the noise level, since noise occurs around the cabin above the recommended limit of 85 dB(A), indicating extremely uncomfortable working conditions (SANTOS FILHO et al, 2004;RINALDI et al, 2008;DAMASCENO et al, 2019;FARIAS & SCHLOSSER, 2020).…”

“…Due to the greater effort of the engine, required by the implements, soil preparation operations with plows, harrows, subsoilers and scarifiers, present the highest noise levels, exceeding the daily exposure limits established by NR-15, reaching a value above 96 dB(A), making the use of PPE necessary (ARCOVERDE et al, 2011;WEDGE;SOUZA, 2012;EGELA & HAMED, 2017). The increase in sound levels at the rear of the tractor is due to the activation of implements (SANTOS FILHO et al, 2004;GOMES et al, 2021).…”

The evolution of agricultural mechanization improved operational and productive performance, reducing human physical effort, and increasing productivity per area. However, the worker remains exposed to various occupational risks when operating an agricultural machine, whether physical, chemical, or biological, increasing the incidence of occupational diseases. The noise generated by agricultural operations is considered one of the main ergonomic factors harmful to the machinery operator and people close to the noise range, affecting not only hearing, but well-being and performance when carrying out work, increasing the possibility of accidents. In research carried out using a mechanized tractor-sprayer set with air assistance in the spray bars, as a way of evaluating the influence of implementing implements on the noise levels emitted by agricultural tractors, an increase in sound intensity was observed when air assistance was used. it was switched on, mainly, in places closer to the noise source, and when the tractor was operating at higher engine speeds. The effects of exposure to noise generated by machinery and agricultural implements are better perceived in the long run, when their effects become more severe. The modernization of the mechanization sector has made it possible to attenuate the noise perceived by operators using cabins, however, employees working in proximity are also exposed to sound emissions, making it essential to use personal protective equipment (PPE), such as ear protectors.
