This utility model discloses a decorative wall panel with good noise reduction effect, belonging to the technical field of decorative wall panels. It includes a wall panel body, with outer shells fixedly connected to both sides of the wall panel body. A locking block is slidably engaged within the outer shell. When installing this decorative wall panel, the operator places the wall panel body in a suitable position and pushes the locking block to slide within the outer shell. The locking block pushes the connecting plate to move, causing a first spring to retract and simultaneously pushing the column upwards, causing a second spring to retract.
