Paper Abstract
This paper compares six different filtering protocols used in Acoustic Emission (AE) monitoring of fatigue crack
growth. The filtering protocols are combination of three different filtering techniques which are based on Swansong-like
filters and load filters. The filters are compared deterministically and probabilistically. The deterministic
comparison is based on the coefficient of determination of the resulting AE data, while the probabilistic comparison
is based on the quantification of the uncertainty of the different filtering protocols. The uncertainty of the filtering
protocols is quantified by calculating the entropy of the probability distribution of some AE and fracture mechanics
parameters for the given filtering protocol. The methodology is useful in cases where several filtering protocols are
available and there is no reason to choose one over the others. Acoustic Emission data from a compact tension
specimen tested under cyclic load is used for the comparison.
