Abstract

The feasibility of the Finite Difference Time Domain (FDTD) technique for acoustic wave created an opportunity for underground cavity detection that poses strong potential for acoustic wave spectrum application. The numerous significant advance has been attained to date, and more technological challenge awaits the optimization of an acoustic system to fill the gap between expectations and practical performance. Despite this tremendous progress, challenging issues related to the FDTD technique for acoustic wave simulation within the underground cavity detection yet to conclude. This review presents the development of the numerical approach in the acoustic wave simulation to excite pulse from the source, with particular emphasis being placed on the recent progress, a portion of travelling waves interact with the underground cavity structure and the cavity properties measurement of the cavity through different approaches.
