The effect and mechanism of seafloor sediments acoustic properties were investigated under various pressure environments through controlling the pressure environment of seafloor sediments. According to the pressure control requirement of acoustic properties experiment of seafloor sediments, the pressure auto-control system was designed and realized. Moreover, mathematical models of its mechanical transmission device and testing chamber were built. The performance analysis on the system was carried out through simulation and experimental research. The experimental result shows that the pressure auto-control system of seafloor sediments satisfies with system design index based on specific control strategy. Therefore, the acoustic properties will be investigated under the good experimental research conditions based on that system.
