This invention provides a tunable gradient-curved sound barrier structure and method based on 3D printing, belonging to the field of environmental noise control technology. The sound barrier unit is fabricated using an integrated molding process. Its core lies in the internal construction of a folded, curled topological skeleton with a gradient distribution along the sound wave propagation direction. This skeleton extends vertically to form a three-dimensional solid. The geometry and spacing of the internal folded channels can be parametrically adjusted to achieve precise matching with the target noise spectrum characteristics. In terms of manufacturing process and materials, this invention employs selective laser sintering technology, using modified microporous nylon composite material as raw material. For highway traffic noise scenarios, this structure effectively extends the sound wave propagation path and induces sound energy dissipation by utilizing gradient-changing folded channels, achieving efficient insertion loss in the two energy-concentrated frequency bands of 315-500Hz and 800-1250Hz. Simultaneously, combined with the micropores and high damping characteristics of the material, it effectively suppresses the coincidence effect.
