The weakly compressible viscoelastic medium permeated with micro-bubbles has strong dispersive because of *** effective sound speed which can be obtained by effective medium method is very small at low frequency *** on the acoustic wave equations and boundary conditions,a method is applied to analyze the reduction of underwater structure-borne noise generated by an axially symmetric ring force on the interior of cylindrical *** structure-borne noise reduction is simulated for the baffle layer of slightly compressible porous *** effects of porosity,thickness,damping and shear modulus of matrix are *** simulations have confirmed that the underwater structure-borne noise can be reduced effectively by the porous *** work is helpful for designing the underwater noise control material.
