The invention discloses a noise reduction guide wall for ground tests of planes. The noise reduction guide wall for the ground tests of the planes is set in a curve shape in the length direction, and surrounds the outer side of launch airflow in the ground tests of the planes. The noise reduction guide wall for the ground tests of the planes comprises a wall body connected with a ground foundation in anchoring mode, wherein a windward face of the wall body is in an arc shape which can guide the airflow obliquely upwards, a leeward face of the wall body is connected with a support truss in anchoring mode, the bottom of the support truss is connected with the ground foundation in anchoring mode, and a stainless steel plate with tiny holes, a sound absorption plate, a sound insulation plate, a cavity layer and a back seal plate are sequentially arranged on the wall body. The noise reduction guide wall for the ground tests of the planes is fastened on the ground foundation, reduces noise by using a plurality of sound absorption structures on the windward face, can guide the jetted airflow to the sky through the windward face in the arc shape, guarantees safety of objects, vehicles and personnel, on the outer side of the noise reduction guide wall for the ground tests of the planes, from two aspects of reducing noise and reducing air speed, guarantees normal work, eliminates all potential safety hazards, strengthens noise pollution treatment, benefits residents in and around airports, and builds the green airports.
