Technical Field

Background

The seabed is the lower interface of a marine sound field environment, and the acoustic characteristic information of seabed sediments needs to be mastered in the researches of marine engineering, marine acoustics and the like. However, due to the diversity of the submarine sediments and the complex marine environment, various research results have strong regional limitations, and almost no research result of a sea area can be completely applied to another sea area, so that the method is of particular significance to the direct in-situ measurement of submarine acoustic parameters.
