Noise Control for Heavy Duty Trucks, a Systems Approach

This paper describes a general noise control system design process. The methodology is applied to heavy duty trucks. The paper describes the benefits, for optimization purposes, of a systems approach versus a component approach. The role of both experimental and predictive approaches on the design process is outlined. Available noise control materials are briefly described, and lastly, an example of the results of the development of a noise control system by the experimental systems approach is provided.
