The invention discloses splicing units of a noise reduction flow guide wall for an aircraft ground test. The splicing units are transversely spliced to form the wall, and windward sides of the splicing units are in arc shapes capable of guiding the air flow into air in an inclining manner; the splicing units comprise a stainless steel micro-hole plate, a sound absorption material plate and a galvanized steel plate in sequence from the windward sides to leeward sides; the flow guide wall is fastened on the ground foundation, and a multi-way sound absorption structure is adopted in the windward sides to reduce the noise; the arc-shaped windward sides can guide the jetted airflow into the air, and therefore the noise and the wind speed are reduced to ensure safety of objects, vehicles and persons of the outer side of the flow guide wall and normal work; any safety hidden troubles are eliminated, noise pollution treatment is reinforced, residents in an airport and periphery are benefited, and the green airport is built.
