Acoustic profile recognition for discriminating between hazardous emissions and non-hazardous emissions
First Claim
Patent Images
1. A method for classifying an emission, the method comprising:
- generating a first acoustic profile at a first acoustic sensor;
generating a second acoustic profile at a second acoustic sensor;
generating a third acoustic profile at a third 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;
comparing the third acoustic profile to a third reference acoustic profile to generate a third difference; and
classifying the emission as a non-hazardous emission when (i) the first difference is greater than a first threshold (ii) the second difference is less than a second threshold and (iii) the third difference is less than a third threshold.

Abstract
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.
