The invention belongs to the technical field of sediment acoustics and particularly relates to a high-pressure triaxial acoustic testing system. According to the high-pressure triaxial acoustic testing system, a pressure chamber is a vertical cabin, and the upper end and the lower end of the cabin are provided with an upper end cover and a lower end cover respectively; the upper end cover is provided with a spoke type pressure transmitter and an exhaust hole; the lower end cover is provided with a water filling/draining hole, a confining pressure loading hole, a counter pressure loading hole,a hole pressure detecting hole and a watertight cable connecting hole; the lower end cover is connected with a confining pressure loading system, a counter pressure loading system and an axial loadingcylinder, wherein the axial loading cylinder is connected with an axial pressure loading system; a sample testing unit is arranged inside the cabin. The high-pressure triaxial acoustic testing systemcan achieve sound velocity
