The measurements of the sound attenuation in sandy sediment of Yellow River(Huanghe)have been made in situ by explosive sources.The attenuation coefficients are determined for thefreqency range of 0.2-2kHz.The experimental results show that the attenuation coefficient α(dB/m)increases approximately as the square of frequency for the frequency range of 0.2-2kHz.Theexperimental results is in agreement with the theoretical results.In addition the sound velocity,density,porosity and grain size distribution of the sediment are given in this paper.
