    In the present paper, determination of the dynamic Young’s modulus of broken speleothems originated in Baradla-Domica cave system (Northern Hungary and Southern Slovakia) is presented. The dynamic Young’s modulus can be calculated based on P and S-wave velocities and bulk density of tested specimens. Two different approaches to determination of bulk density of irregular speleothem specimens are presented - determination of bulk density by standard Water displacement method and by X-Ray Computed Tomography.
