Underwater acoustic engineering is a national key discipline. As one of the most important research units in the basic research of underwater acoustic technology in China, the State Key Laboratory of Underwater Acoustic Technology basically covers all research fields of underwater acoustic technology, with the harmonious development of basic research, applied technology research, underwater acoustic equipment development and system integration technology research. This subject trains high-level underwater acoustic research talents who take into account acoustics, vibration and signal processing. Degree winners should have a solid knowledge of acoustic vibration theory, master the characteristics and development direction of underwater acoustics, and have the ability to engage in basic research on underwater acoustic engineering applications. Through the training of master's study and thesis work, we can cultivate the independent working ability of theory and practice and make innovative research results on practical problems related to this discipline.
