An impact acoustic free-fall setup was developed to distinguish the difference between the frequency of undamaged and damaged rice kernels using frequency analysis. The study determined the different design parameters of the impact acoustic system that would classify undamaged and damaged rice kernel for a particular/specific microphone. Two cardiods and one hypercardiod (AKG CK 91, Neumann KM 184, and Shure Beta 58A) microphones were used for this study. All three microphones underwent the… CONTINUE READING
