FEASIBILITY STUDY OF CONCEPTS FOR AN ALL-WEATHER NOISE TEST FACILITY FOR TRUCKS

A feasibility study was performed to both generate and evaluate concepts that would have potential for developing an all-weather method for truck noise testing. Although trucks were emphasized, buses were taken into consideration, and the final choice of method was based on accommodating both vehicle types. As a basis for starting, it was determined that the vehicle had to remain in place within a weather-proofed enclosure. Thus, dynamometer systems and building design were included as part of the analysis. A more fundamental issue involved the purpose of the measurements: should the test method be designed to simulate a driveby test, that is SAE J366b, and thereby correlate with an established, existing data base; or should the method provide another, possibly more useful measure of noise such as sound power? Rather than choose either/or, the study was directed toward both viewpoints. /HSRI/
