PURPOSE: A soundproof wall is provided to block noise from road or railroad with improved noise elimination effect and prevent the exposure of posts. CONSTITUTION: A soundproof wall comprises a back plate(10), an assembly member(20), an interference member(30), and a sound absorbing material. The interference member includes an anti-drooping part which is bent to the top and bottom between a fixing protrusion and an interference slit and supported by the outer wall of a protrusion of the assembly member to prevent the drooping of the interference slit. The shock absorbing material is installed inside the back plate and absorbs noise flowing in between interference slits.
