President Elect JOHN SANDERSON introduced Bob Bernhard, Professor of
Mechanical Engineering and Associate VP for Research at Purdue University.
He heads the Institute for Safe, Quiet and Durable Highways at Purdue. We
learned that there are for ways the noise is made when energy is created by tires
on pavement, The Hammer; The Clapper, The Squeaker, and The Suction Cup.
This energy is amplified giving us The Horn Effect, The Pop Bottle Effect, The
Organ Pipe Effect, and The Loud Speaker Effect. Efforts are being made to
improve pavement to create less noise when rubber hits the road.
