摘要

Tractor noise consists of engine noise, exhaust, intake fan and mechanical noise created by combustion, gears, cams, bearings and pumps, etc. Its noise spectra cover the entire audible range from 20 Hz to 20 kHz.The severity associated with noisy tractor may be annoying to varying degrees, lack of concentration, fatigue, rhythm disturbance and damage to hearing. In this paper noise of the tractor (John Deere (5103)) at the operator's ear level and for bystander position was measured during no load (NL) and spraying operation using an areo blast sprayer at different engine speeds. The results showed that noise level during spraying operation higher than during NL condition. It is found that the effect of engine speed was significant at the 5 percent level of significance. It is observed that noise at a tractor operator's ear level during spraying operation using an areo blast sprayer was higher than the permissible level (85 dB (A)) which was given by Occupational Safety and Health Administration (OSHA) and National Institute for Occupational Safety and Health (NIOSH).
