Proper sensor placement is the crucial step and a premise for precise AE source location estimate. Using the algorithm for finding the shortest ways in discretely defined bodies it is possible to design three parallel tools how to evaluate problematic areas, namely the location sensitivity, similarity and ambiguity maps, available even for non-continuous or anisotropic materials. To check the numerical forecast of location capabilities of given sensor configuration, theoretical results were reviewed with the data measured during real experiment.
