摘要

The "Comparisonics" sound-matching algorithm computes signatures to characterize audio data and compares the signatures to measure the similarity of sounds. This algorithm is general purpose: it can compare any sounds and can monitor sounds from any machine. After a baseline recording is characterized, signatures are derived from the current sound and compared in real time with the baseline signatures. Similarity scores are computed continuously, reflecting the similarity of the current sound to the baseline, and an alert can be given if the similarity falls below a threshold. In addition, the current sound can be compared with known "error" sounds to identify specific faults. This algorithm can operate in a wireless sensor network and be deployed in a factory or on a ship to monitor an unlimited variety of machinery.
