SonicSort: Classification of Materials Using Acoustic Sensing

This invention is about material classification e.g. plastic, glass, using acoustic sensing. The object is excited acoustically and the response is analyzed. The acoustic techniques include knock-sound analysis, sound speed measurement or both, different materials can be classified based on the response of dominant frequency, sound speed or even echo decay analysis.
