Acoustic profile recognition for discriminating between hazardous emissions and non-hazardous emissions

摘要

A method for classifying an emission includes generating a first acoustic profile at a first acoustic sensor; generating a second acoustic profile at a second acoustic sensor; comparing the first acoustic profile to a first reference acoustic profile to generate a first difference; comparing the second acoustic profile to a second reference acoustic profile to generate a second difference; and classifying the emission as one of a hazardous emission or a non-hazardous emission in response to the first difference and the second difference.
