A nondestructive quality inspection technique using acoustic impulse response method was developed for eggahell inspection, An experimental system was built to generate the impact force, to measure the response signal and to analyze the frequency spectrum This system includes an impulse generating unit, an egg holding seat, a microphone with preamplifier, and a DSP board installed on Personal Computer A simple algorithm was developed for crack detection Using the developed system with algorithm, crack detection ability was evaluated and the error rate to estimate the normal egg as cracked was found to be 4% and the error rate to estimate the cracked egg as normal was also found to be 4% This system could be adopted in industry with some modification.
