Abstract:

Recent emphasis on the reduction of environmental pollution has prompted the legislation of many new standards defining maximum noise limits inside of, and in close proximity to all types of commercial and military automotive vehicles. These stantards require the collection of noise emission data on both newly produced and inservice vehicles for determination of conformance. Since every vehicle to be produced or currently in existence that falls within the jurisdiction of the standards cannot be measured individually due to time and cost constraints, a method of accurately predicting the noise profile of a large population of similar type vehicles utilizing data collected from only a limited sample of the population is required. This paper presents such a statistical method, and illustrates its application utilizing data taken on multiple samples of several types of military tactical vehicles.
