“…Although the noise levels observed on both sides seem similar, the right side showed slightly higher levels than the left side, which were caused by some engine components located on the right side of the tractor's front. Baesso et al (2017), studying noise levels observed in several distance points from comparable tractors of those investigated, found similar values in the right and left sides, which corroborates to the results found by this work.…”

Níveis de ruído emitidos por tratores agrícolas com e sem acionamento de implementos Os níveis de ruído emitidos pelas máquinas agrícolas podem ser prejudiciais à saúde do trabalhador e, por vezes, negligenciados no meio rural. Este trabalho teve como objetivo mensurar os níveis de ruído emitidos por três tratores agrícolas de diferentes potências acionando dois tipos de implementos para avaliar se havia riscos à saúde dos operadores e trabalhadores de apoio ao redor da operação. Os dados de ruído foram coletados por decibelímetro em dez pontos de cada lado da máquina (frente, trás, esquerda e direita) para um total de 40 pontos ao redor de cada trator. Três tratores diferentes foram avaliados em diferentes cenários: sem implemento, acoplando e acionando uma esparramadora de corretivo e acoplando e acionando uma enxada giratória. O trator foi estacionado no centro da mistura com uma rotação do motor que garantiu 540 rotações por minuto (RPM). para a tomada de potência (TDP) durante toda a coleta de dados. Os dados foram analisados por meio de gráficos, regressão linear e análise de agrupamento hierárquico. Os resultados indicaram que os níveis de pressão sonora em todas as situações estudadas ultrapassam os limites da norma regulamentadora (NR) 15, tornando os protetores auditivos indispensáveis durante a jornada de trabalho. Palavras-chave: ergonomia; conforto acústico; mecanização agrícola; nível de pressão sonora. ABSTRACT: The noise levels emitted by agricultural machines can be harmful to the worker's health, and it is sometimes neglected in rural areas. This work aimed to measure the noise level emitted by three agricultural tractors of different power activating two types of implements to assess whether there were risks to operators' health and the supporter workers around the tractor. The noise level data were collected using a decibel meter in ten points on each machine side (forward, rear, left, and right) for a total of 40 points around each tractor. Three different tractors were evaluated in different scenarios: without any implement, coupling and activating a spreader, and coupling and activating a rotary hoe. The tractor was parked at the centre of the mash with an engine speed that ensured 540 rotation per minute (RPM). to the power take-off (PTO) during the entire data collection. The data were analyzed by charts, linear regression, and hierarchical clustering analysis. The results indicated that the sound pressure levels in all of the studied situation exceed the standard's limits regulatory standard 15, making hearing protectors essential during the working day. Keywords: ergonomics; acoustic comfort; agricultural mechanization; sound pressure level.

“…On comparing the HAV of all the power tillers, it is found that magnitude of vibration is increased with the increase in the power rating of power tiller. The similar findings were discussed by the various researchers (Celen et al, 2003).…”

Every day, millions of agriculture workers were exposed to noise and vibration at work and all the risks of it can entail. This paper examines the noise and vibration characteristics of popularly and most commonly used power tillers having power rating of 11 kW, 9.5 kW and 4.4 kW. Data were collected at four levels of engine speeds for stationary condition of power tiller and two operation modes for tillage and puddling operations. With the increase in engine rpm from ¼ to full of power tillers, noise and vibration magnitude was increased and the allowed exposure was reduced from 7.62 h to 2.48 h for PT-I and 9.83 h to 3.14 h for PT-II and 5.76 h to 2.21 h for PT-III during puddling operation. The SPL of the power tillers under the study was more than the permissible limit of sound level for 8-hour duration/day as recommended by ISO and hence require suitable measures to protect the operator and workers around these power tillers against excessive sound. All three power tillers showed the maximum magnitude of vibration at handle which directly interacts with the body of operator.

“…According to the maximum engine speed of the MF 285 tractor (Table 1) and based on previous studies, the engine speed of 1000 and 2000 rpm was selected for sound level measurements 15,16 . Sound level measurements for both roads were performed at right ear of the operator and bystander position according to the standard method of ISO 362 17 .…”

“…The surface of paved roads increases the sound level at bystander positions 14 . Also, engine speed was related to sound levels at bystander position and right ear of the operator in New Holland L95 tractors, and when the engine speed changed from 1000 to 2000 rpm, sound levels increase by 6 dB 15 .…”

This study aimed to determine the noise levels of a Massey Fergusson 285 tractor during movement on dirt and paved roads. The Massey Fergusson 285, 75 hp tractor accompanied by a trailer with one-ton load travelled on dirt and paved roads. The test field had 20 m length and 3 m width as defined according to international standards. The sound levels were measured with different gears and for engine speeds of 1000 and 2000 rpm at bystander position and right ear of operator. The difference between A-weighted sound levels for bystanders and right ear of operator, in engine speed of 1000 for dirt and paved roads, was 13.7-15.9 and 10.9-14.7 dB and, in engine speed of 2000, was 12.7-16.1 and 9.8-13.8 dB, respectively. In the bystander position, the sound levels for both engine speeds were lower on the dirt road compared to the paved road. The sound level at the right ear of the operator at engine speed of 1000 rpm was lower than ACGIH standards (85 dB whereas it was higher in engine speed of 2000 rpm for both roads, except in first low and first high gears on the dirt road. Based on similar distance for measurement points on both roads, the lower acoustic impedance of dirt compared with pavement surface provides less noise reflection which leads to lower noise levels in bystander position. The farmers who work near dirt roads are exposed to lower sound levels than those working near paved roads.
