Paper Title
Effect of Tractor usage on Noise Level

Abstract
Noise is the most significant problem in agriculture. Most of the farmers and farm workers are exposed to noise levels greater than the recommended levels (85 dBA). This study was conducted to have information about tractor farm noise levels and their emission. The sources of noise were identified and it was found that the most of noise generation was at the transmission and muffler opening, engine, bonnet and radiator fan. Tractor needs proper maintenance for their efficient working or else noise emission will be higher with increasing tractor life. Proper scheduled repair and maintenance along with use of vibration isolators may help in noise reduction.
