Ship cabin noise transmission path analysis method

The invention discloses a ship cabin noise transmission path analysis method, which comprises the steps of establishing a statistical energy analysis model according to a ship drawing; setting attributes of each subsystem in the statistical energy analysis model according to drawings and data; calculating an internal loss factor of each subsystem and a coupling loss factor between the subsystems,and establishing a loss factor matrix of the whole system; converting the loss factor matrix into a path efficiency matrix, and establishing a path efficiency weighting graph for noise transmission path analysis; and solving the first k shortest paths of the weighted graph by using an algorithm of the shortest path problem, so as to obtain the first k noise energy transfer paths from the noise source to the target cabin. The cabin noise transmission path analysis work can be completed at the initial stage of ship design, the limitation that real ship test analysis can only be conducted after aship is built is overcome
