The utility model discloses a metal heat preservation layer with a noise reduction structure, and relates to the technical field of metal materials, according to the metal heat preservation layer with the noise reduction structure, due to the fact that a sound absorption layer is made of sound absorption cotton materials and has the characteristic of absorbing sound waves, most sound wave energy cannot penetrate through the sound absorption layer, and noise is reduced. The noise reduction function of the metal heat preservation layer is achieved, the rubber soft cushion layer is attached to the metal panel, noise generated by collision between metal and the outside is reduced, certain noise consumption is formed through the first through hole and the second through hole, meanwhile, the absorption effect of the sound absorption layer on sound wave energy is improved, multiple noise reduction modes are matched, and the noise reduction effect is improved. The noise reduction function of the metal heat preservati
