An increase in the grain/pore size can cause the received echo signal to be distorted due to the preferential attenuation of the high‐frequency components of the transmitted acoustic signal. Therefore, a rock acts as a low‐pass filter and the property of the filter has a linear relation to the grain/pore size. The results have shown that P‐ and S‐wave attenuations can be used to characterize selected internal characteristics of a rock. For example, an increase in the differential stress can cause an increase in the attenuation, due to the sensitivity of the S‐wave to microcracks.
