Agricultural tractor noise is a serious problem of vital concern for tractor operators. Work has been done at South Dakota State University and other institutions to reduce the noise level produced by the agricultural tractor by utilizing various exhaust control methods and insulating cabs. Acoustical ear muffs have not been evaluated as a noise control method. These ear muffs have great potential to offer immediate noise reduction for a very low cost. The objective of this study was to evaluate a commercial acoustical ear muff for use by farm tractor operators as a noise control method under field conditions.
