The elevator double-layer sound insulation structure comprises a first sound insulation structure, a second sound insulation structure and an anti-disengaging limiting structure, and the second sound insulation structure comprises a car top plate and a car wall plate; the anti-falling limiting structure is used for preventing the first sound insulation structure from falling off from the second sound insulation structure; the first sound insulation structure comprises supporting frames fixedly arranged on the second sound insulation structure, and the supporting frames form a rectangular lattice-shaped array. The elastic film covers the supporting frame; the closed cavity is defined by the supporting frame, the elastic film and the second sound insulation structure; and the resonance sound absorber is arranged on the elastic film. The sound insulation performance of the lift car can be effectively improved, and external noise entering the lift car through the lift car is reduced. 本发明公开了一种电梯双层隔音结构，包括第一隔音结构、第二隔
