the internal defects of any materials. During the processing stages these techniques are very crucial task to be considered because earlier rejection of the compacted materials capable to save the manufacturing costs before they are experienced further processing levels. In this work, sound generated during the powder compaction of metallic and nonmetallic powders are studied. Different reinforcing percentages are used to examine their effect on the sound generations. Sound detectors are attached on the surface of the mould and identical sound filtering software package is used to filter out the unwanted sound. Prior to compaction, surface roughness of the internal mould is determined and it is followed the industrial value of the surface roughness and another mould is highly polished. It is found that higher fraction of the reinforcing elements and the influence of surface roughness affected the rate of sound generation during the quasi-static powder compactions.
