The invention discloses a method for controlling structural acoustic transmission on the basis of a combined type vibration isolation device. The method includes steps of S1, determining the required combined type vibration isolation device according to parameters of isolated mechanical equipment; S2, vertically placing the isolated mechanical equipment on the combined type vibration isolation device; S3, adjusting the weight of a middle counterweight of the combined type vibration isolation device; S4, adjusting the natural frequency of the combined type vibration isolation device so that the natural frequency of the combined type vibration isolation device is lower than the structural vibration acoustic transmission frequency generated during operation of the isolated mechanical equipment; and S5, fixing the isolated mechanical equipment. The method has the advantages that propagation of noise of high-frequency structure is controlled by a combined type vibration isolation system, the vibration isolation device is arranged between the isolated mechanical equipment and a carrying foundation, performance parameters of upper and lower vibration isolators, a damper and the middle counterweight are matched with one another, the middle counterweight absorbs energy, and the spring and rubber isolators effectively isolate vibration, so that energy transmission of the structural noise is reduced, and the structural acoustic transmission of mechanical vibrating equipment is efficiently isolated.
