Abstract
A system and method for determining material yield and/or loss from a harvesting machine using acoustic sensors and advanced signal processing capabilities is presented. The system consists of a sensor housing with an opening on one side of the sensor housing, a strike plate designed to fit into the opening, and an electronics module comprising a microphone and a signal processor designed to capture the sound waves created when material impacts on the strike plate, and convert them into an audio signal indicating the amount of material impacting the sensor at a given time.
