Othman, A. Elkholy, A. Seireg] An experimental investigation into the nature of the noise generated when a stylus travels over a frictional surface has been carried out using several engineering materials. The relation between the sound pressure level (SPL) and surface roughness under various contact loads was established. An acoustic device was designed and constructed to be used as a reliable tool for measuring roughness. For each tested material, it has been found that the filtered noise signal within a certain spectrum bandwidth contains a specified frequency at which the amplitude is maximum. This frequency was named the dominating frequency and was found to be a material constant independent of surface roughness and contact load. It was also found that the dominating frequency for a given material is proportional to the sonic speed in that material. Society for Experimental Mechanics, Inc., 1990 Othman M.
