Assessment of Effective Variables on the Acoustic Response for Eggshell Crack Detection

Eggshell crack detection in grading lines is very important. In recent years, various methods have been studied for this purpose. One of the conventional methods used in the eggshell crack detection is acoustic response. With this method, types of cracks which are apparent defects by analyzing the acoustic response to mechanical impact will be recognizable. In this research, the effects of factors related to acoustic system such as ball material, impact angle and microphone position on acoustic response in detection of cracks types were investigated. Accordingly, factorial experiments in a completely randomized design with three replications were performed. The results showed that levels of ball material, impact angle and microphone position and cracks types had significant effects (P
