Abstract

Abstract: The J-divergence has been brought forward as an improvement of directive divergence. By introducing a
new kind of evaluation index called Normalized Key-points Height(NKH), a simulation and a cabinet model test has been
proposed to evaluate the effectivness of five different distance concepts including Euclidean distance on four kinds of acoustic
faults. The result shows that the J-divergence is the best choice for acoustic fault detection.
