Adaptive filtering of sound pressure signals for monitoring machinery in noisy environments

A Comparative Study of the Effectiveness of Adaptive Filter Algorithms, Spectral Kurtosis and Linear Prediction in Detection of a Naturally Degraded Bearing in a Gearbox

“…More recently, the use of adaptive filters has been applied to monitor bearings [18][19][20]. This concept is based on the Wold Theorem, in which the signal can be decomposed into deterministic and non-deterministic parts [21].…”

An automated low-cost condition monitoring system for quality control of automotive speedometers

“…Most of the literature concerning automotive speedometers, such as reference [1], employs image processing methods for the inspection of systems. However, sound analysis has been reported for condition monitoring of a variety of systems such as machining operations [2], rolling element bearings [3], machinery in noisy environments [4] and uid dynamics [5]. This paper reports a novel low-cost approach for automated monitoring system and inspection of automotive speedometers that can be performed in the factory to ensure non-defective products.…”
