The invention relates to a noise reduction interior system for a special vehicle cab. The system comprises any one or a combination of more of a sound absorption interior structure, a high-strength multi-layer composite floor structure and an engine compartment sound absorption and insulation structure. The roof sound absorption structure sequentially comprises a first sound absorption material and a first protective surface layer from inside to outside, and the first sound absorption material is attached to the roof. The high-strength multi-layer composite floor structure sequentially comprises floor leather, a damping composite sandwich structure and a second sound absorption material from top to bottom, and the second sound absorption material is attached to the ground. The engine compartment sound absorption and insulation structure sequentially comprises a third sound absorption material, a damping steel plate, a fourth sound absorption material and a second protective surface layer from inside to outside, the third sound absorption material is attached to the inner side of the compartment plate, and the fourth sound absorption material is attached to the outer side of the compartment plate. Compared with the prior art, the noise reduction frequency range is wide, and the application range is wide.
