An Experiment for Relating Objective and Subjective Assessments of Truck Tire Noise 720928

The SAE Truck Tire Noise Subcommittee, as a part of its efforts toward writing a measurement and evaluation procedure, conducted an experimental test program for relating objective and subjective assessments of truck tire noise. The program comprised a series of designed experiments involving 6 trucks, 18 sets of tires, and 5 vehicle operating modes. The test runs were presented in random fashion to a jury situated alongside a highway. The subjective noisiness ratings and the A-weighted sound levels obtained verified the design objectives of the experiment and, further, correlated well with each other.
