A surgical positioning system includes an emitter secured to a medical implant; at least three microphones; at least one processor; and a memory. The emitter has a speaker and a power source. The memory stores instructions for execution by the processor that, when executed, cause the processor to receive, from each of the at least three microphones, information about a detected sound; and calculate, based on position information corresponding to each of the at least three microphones and the received information, a position of the implant.
