Mean reflection coefficients of plane acoustic waves incident on a liquid-polycrystals interface are examined experimentally and numerically. The mean reflection coefficient is defined as the complex average value of the reflection coefficient for all the crystals existing in the measurement area. Experiments are performed for a texture controlled low-carbon steel which can be identified as the transversely isotropic polycrystalline material. The measured reflection coefficient agrees qualitatively with the mean reflection coefficient calculated by the integration of the reflection coefficients for each single crystal on the measurement area.
