%X Based on the viscosity acoustic absorption theory, Rock material is natural low-pass filter of acoustical wave. For the different frequency response of rocks, the frequency composition of wave changes with the absorption in each kind of rocks. The degree of abundance of frequency in the receiving signal is closely related to the properties of rock materials. The harder the rock is, the more abundant the receiving acoustical signal component is. On the contrary, the receiving signal is only the low frequency component, the high frequency component fade down because of filtration. The researching achievement can be used to research the weathering, crushing, strength and anisotropy of rock-mass, and can be developed into a general experience method of rock-mass in the engineering exploration, testing and construction.
