problem is pro- posed.Acoustic source localization in a three- dimensional structure is
realized by the time difference information and space coordinates of sensors.The operation and
calculation are simple.The experiment cost is also reduced.This experimental method can not
only intuitively realize the three - dimensional acoustic emission source localization
process，but also realize the measurement of sound velocity. This simple experiment method
can deepen students' understanding of physics issues and increase their interest in
acoustic emission technology and source localization technology. The proposed experimental
method is suitable for popularization.
