Abstract
From its very beginning, agriculture has been associated with hazards. Most hazards associated with early-day farmers were linked with animals. Today’s highly mechanized agriculture has greatly increased the number of perils, many of them related to tractors and machinery. One type of hazard which is evolving from modern farming methods is that of occupational deafness caused by tractor noise. This is a by-product of farm mechanization, and unless future tractors are quieter than those presently in use, the incidence of this occupational disease will increase.
Unlike many physical injuries, occupational deafness usually occurs without discomfort or pain in the ears. Because of this most people affected are unaware of any hearing loss until the noise exposure has been of sufficient severity and duration to cause considerable hearing damage.
The primary objective of this study was to analyze the effects of the tractor exhaust stack location on the noise levels at the operator’s station.
