Factors Affecting the Accuracy of Acoustic Emission Sources Localization,designed and conducted where the velocity-free methods and traditional methods are applied to source localization. The results reveal some regulations concerning location accuracy and based on them some suggestions are put forward to improve location accuracy in different conditions.

wave velocity changes dynamically in time and space.Improve.In this book, we proposed velocity-free localization methods for acoustic and microseismic sources. This method does not require predetermination of wave velocity, which is a dynamically adjusted free real-time parameter. These methods sol
