The invention discloses a ballast injection type device and a method for measuring acoustic characteristics of a submarine sediment in situ. The device comprises three parts including an external support mechanism, an injection driving mechanism and a monitoring and measuring mechanism, wherein the external support mechanism comprises a polygonal support frame and a guide pipe which are fastened by bolts; the injection driving mechanism comprises a hoisting head, a guide rod, a movable press plate, a mounting flange, ballast lead blocks, probing rods and other components; the monitoring and measuring mechanism comprises a state monitoring sensor module, an acoustic sensor module and a monitoring and measuring circuit module. The measurement process is completed in a real-time monitoring mode and a self-containing mode according to the fact that whether a communication cable is connected between the measuring device and a deck control platform. By means of the external support mechanism, the stability of the m
