Níveis de ruído no posto de operação de um trator agrícola na operação de semeadura

Abstract: A utilização de tratores agrícolas expõe os operadores a diferentes agentes que podem ser nocivos à saúde, dentre eles, o ruído, que dependendo da intensidade, leva à perda gradual da sensibilidade auditiva dos operadores. Neste sentido, este trabalho teve como objetivo avaliar o nível de ruído que chega ao posto de operação em um trator agrícola tracionando uma semeadora-adubadora de precisão, equipada com dois tipos de mecanismos sulcadores de fertilizante, em quatro velocidades de trabalho e duas configuraç… Show more

“…The development of agricultural tractors occurred through the modernization of the agrarian sector, thus, the wheeled agricultural tractor became the most used vehicle in rural properties around the world, with a fleet of about 29 million tractors, with Brazil being one of the world's largest producers of tractors, with 98% of the machines sold in the country of national manufacture (BAESSO et al, 2015;NUNES et al, 2016;FARIAS & SCHLOSSER, 2020). In 2020, of the total production of agricultural machinery, 70.9% were wheeled tractors, 11.3% backhoe loaders and 10.4% grain harvesters, according to data from the National Association of Automotive Vehicle Manufacturers -ANFAVEA.…”

“…Na agricultura brasileira, estudos acadêmicos têm sido realizados com tratores agrícolas e seus implementos, avaliando-se separadamente os agentes de risco ruído (MAGALHÃES; CORTEZ;NAGAHAMA, 2012;BAESSO et al, 2017;SILVA et al, 2018;DAMASCENO et al, 2019;OLIVEIRA et al, 2020;FARIAS;SCHLOSSER, 2020;SILVA et al, 2021) e vibração (SANTOS et al, 2016;SANDI et al, 2018;SANDI et al, 2020) existindo, no entanto, poucos trabalhos que considerem a exposição simultânea a estes agentes de riscos ambientais, especialmente nos tratos culturais do cafeeiro.…”
