The marine sediment acoustic characteristics (such as so und speed and attenuation) as well as their relationship with physical characteristics (including soil mechanics) are two important research topics in marine sediment acoustics.A new developed real-time monitoring multi-frequency in situ sediment geoacoustic measuring sysem was introduced.The geoacoustic measuring system is designed for sound speed measurements of the seabed measuring.The measuring frequencies are 8,10,12 and 15 kHz.A transmitting waveforms,receiving gain and sampling length could be changed according to sediments.A sampling rate is designed from 500 kHz to 2 MHz,and an operating depth is 300 m.The geoacoustic measuring system has a tilt sensor and eight channels expansion.A set of in situ sound speeds of four different frequencies is observed in the Hangzhou Bay.
