Detection of load by sound-processing

A method for detecting load in a machine by a load detection system, the machine including a loading receptacle, the load detection system including a sound detection device, a signal-to-data processor that includes a sound-processing module, a data aggregator, a data comparator, the method comprising:

• recording a continuous rolling audio signal sample by the sound detection device, the continuous rolling audio signal sample corresponding one of:
• an inflow event fact;
• and
• an outflow event fact;
• monitoring continuous rolling audio signal sample for initial indicators of one of the inflow event fact and the outflow event fact;
• duplicating a recorded continuous rolling audio signal sample for audio pattern recognition;
• generating a filtered audio sample from the continuous rolling audio signal sample by removing noises unrelated to the inflow event fact and the outflow event fact;
• computing a score for similarity between the filtered audio sample and pre-defined inflow audio signal templates and outflow audio signal templates, thereby providing a highest scored pattern match;
• logging the highest scored pattern match upon reaching a minimum threshold, wherein a scored pattern match remains unrecognized if the highest scored pattern match fails to reach the minimum threshold;
• outputting a data event based on the highest scored pattern match on at least one of an output port and a user interface.
