Classifying machinery sounds to detect abnormal operation such as bearing noise, belt squeal, pump cavitation, or motor imbalance without physical contact sensors. Uses audio spectral analysis instead of accelerometer-based vibration monitoring. Deployed as a non-invasive retrofit on existing equipment — mount a microphone near the machine, no mechanical attachment required. Particularly useful for legacy equipment where installing contact sensors is impractical.
