Acoustic reflection from the bottom and sound propagation are closely connected. In this paper reflection coefficient behavior at high frequencies (above 1 kHz) for the layered absorbing bottom was investigated. Influence of the layered bottom parameters on acoustic propagation was considered. It was shown that for the same set of bottom parameters the sound reflection coefficient at low grazing angles decreases when the grazing angle decreases. Behavior of frequency and angle resonances of the reflection coefficients was analyzed. Two types of bottom connections between sets of bottom parameters and sound losses in a wide frequency band were ascertained.
