摘要：

The paper discusses the results of numerical and experimental investigation of detecting an additional mass placed on an isotropic rod, using changes in propagating waves. For the numerical modeling the spectral element method was applied. The proposed numerical model was verified experimentally with the IFFM PAS laboratory equipment.
