features at work. Exposure also depends strictly on the noise produced by the working equipment
(walking tractor or tractor). Considering the data in the literature relating to similar equipment, it can
be considered an approximate value of exposure to the noise (determined by the machine and the

walking tractor or tractor) between 90 dB (A) and 95 dB (A).
Verify the level of exposure to the noise with the proper instruments each time any work is performed. Follow the legislative
references of your country to identify the personal protective necessary equipment.
