    Abstract

    The author employs the Kjartansson absorption model to prove that intrinsic dispersion of seismic wave velocities in absorbing
    media is a basic factor responsible for the differences between elastic rock parameters measured dynamically and statically.
    Dispersion of Young’s modulus predicted by this model for a frequency range from millihertz to tens of kilohertz matches well
    the experimental data obtained for polyvinyl chloride plastic used as a test material in the study case.
