Truck Noise 1-A :

Abstract

This is a special report within a series of reports emanating from an interagency agreement with NBS to perform a wide variety of truck and passenger car tire noise research. AbstractThis report presents the A-weighted sound level and one-third octave band spectral data resulting from a study conducted to characterize the noise generated by military truck tires. The study was conducted by the National Bureau of Standards in cooperation with the U.S. Department of Transportation under the sponsorship of the U.S. Army Tank-Automotive Command. The data base established will allow for comparison of the tire noise generated by military and commercial truck tires.The study investigated the influence of load and speed on the noise generated by tires with four different tread designs: the standard Army tire, a retread of Army design and commercial tires with rib and cross-bar type tread patterns. Army and commercial trucks were utilized as test vehicles.In addition, the report includes a discussion of the measurement and analysis techniques utilized for the establishment of this data base.17.
