The invention relates to the field of vibration and noise reduction plates, and provides a vibration and noise reduction super-hybrid laminate and a preparation method and application thereof. The vibration and noise reduction super-hybrid laminate comprises a plurality of layers of metal plates, a functional layer is arranged between every two adjacent metal plates, and each functional layer comprises a polyether-ether-ketone adhesive film layer, an aramid fiber textile layer and a carbon fiber reinforced polyether-ether-ketone prepreg layer; the number of the metal plates is larger than or equal to 2. Furthermore, the vibration and noise reduction super-hybrid laminate further comprises a damping material layer. The vibration and noise reduction super-hybrid laminate provided by the invention has the characteristics of a metal plate and a polyether-ether-ketone composite material, gives full play to the viscoelastic characteristic of a polymer polyether-ether-ketone adhesive, and obtains a laminate structure with a high damping coefficient by utilizing the constraint damping structure principle of interfaces among layers and the noise reduction characteristic of a hollow structure of an aramid fiber textile; vibration of sound waves in laminate transmission is effectively reduced, and the effect of vibration and noise reduction is achieved.
