ABSTRACT:
An acoustic sensor system for detection of insects in agricultural commodities. The system includes isolation structure for isolating the agricultural commodities from external noise and vibration, an improved acoustic sensor for detecting sound from within the agricultural commodities and for generating a signal in response to sound so detected, and a user recognizable output such as earphones or a light emitting diode for producing user recognizable output in response to signals generated by the acoustic sensor.
