Summary:

TIRE thump has gained prominence as passenger cars have become quieter and roads smoother. Studies at the CM Proving Ground dating back to 1940 have shown thump to be a very complex example of the simple phenomenon that combining two closely spaced frequency components will produce a certain beat.Here the authors detail what has been learned about the physical characteristics of car and tire which go into producing thump of various frequencies and loudnesses. They also describe a newly developed portable instrument which measures the depth of modulation of the beat between two frequencies, thus serving as a uniform standard of tire thump severity
