An Example of Noise Control Treatment for Construction Machinery Cab Interiors

The effect of noise on the operator has become of increasing concern to manufacturers of construction machinery in recent years.

Although the noise generated by heavy duty construction equipment is much greater when compared to other types of machines such as the passenger car, the problems are similar. Many of the lessons learned in reducing interior noise within the automobile can be used to reduce noise within the operator's cab of construction machinery. This paper represents the results of a joint effort between Fiat-Allis Construction Machinery, Inc., and Globe Industries, Inc. to apply these lessons to reduce the noise within the cab of a medium sized crawler tractor.
