The article presents the results of studies of pile continuity by seismic acoustic flaw detection. The test results revealed the dependence of soil homogeneity on the signal frequency. At the interface of two different density soils, the sound wave is reflected and partially passes on, creating characteristic peaks of false defects. In order to eliminate false defects, geological studies of soils with layer-by-layer occurrence are necessary.
