Machine and operating environment diagnostics, detection and profiling using sound
First Claim
1. A method for source profiling using pressure waves, the method comprising:
- profiling known pressure wave sources using time domain characteristics, wherein profiles of the known pressure wave sources correspond to respective cyclical pressure waves;
acquiring pressure wave data;
analyzing acquired pressure wave data by performing an audio-based autocorrelation analysis on the acquired pressure wave data to match the acquired pressure wave data to a matching profile of a known pressure wave source corresponding to a respective cyclical pressure wave from among the profiles of the known pressure wave sources; and
detecting a source to be the known pressure wave source of the matching profile upon determining the match.
