This paper investigates the problem of reflection of longitudinal displacement waves in a medium containing a distribution of void pores. It is observed that three types of waves, traveling at three distinct speeds, may exist in an elastic medium with void pores. The critical frequency has been detected. Amplitude ratios have been presented. It is found that the presence of void pores modulates the wave velocities and amplitude ratios to a considerable extent. Numerical calculations have been made and graphs are drawn to exhibit the role of void pores in the problem under consideration.
