A soundproof panel is provided to reduce the construction cost of a structure by integrating a noise reduction apparatus noise in the conventional soundproof panel. A soundproof panel(1) includes at least one cavity formed inside the panel, a wind pressure and noise reducing apparatus(4) which is built in the cavity, and a casing having a plurality of air inlets(2b) and air outlets on the front and rear surfaces to help smooth air flow. The wind pressure and noise reducing apparatus comprises an inner casing having a plurality of air inlets(4c) and air outlets, a fan(4e) with a bearing, an end cap(4b) mounted on both ends of the inner casing to fix the rotation axis of the fan, and a gasket(4d) formed on the top and bottom inside the inner casing to reduce the rotation noise of the fan.
