Sound speed and attenuation of plane acoustic waves in a sandy sediment

During the sediment acoustic experiment SAX99, several researchers measued sound speed and attenuation. Together, the measurements span the frequency range of about 125Hz ~ 400kHz. In this paper, in order to establish the acoustic attenuation model of buried mines, the experimental data of sediment acoustic experiment (SAX99) have been cited, sound speed and acoustic attenuation of Biot-Stoll model, Buckingham model and BICSQS model in a sandy sediment have been analyzed. The results show that, sound speed and attenuation of three prediction models have different matching characteristics with experimental data. In the frequency range of 125Hz~400kHz, the sound speed of Biot-Stoll model matches well with the experimental data; in the frequency range of 2.6kHz~50kHz, the attenuation of Biot-Stoll model matches well with the experimental data.; in the frequency range of 50kHz~400kHz, the attenuation of BICSQS model and Buckingham model match well with the experimental data.
