An apparatus and method for reducing noise from aircraft high power ground run-ups. The ground run-up enclosure includes a vented tall rear noise attenuating wall and a separate jet blast deflector to direct the jet blast up and out of a facility. The vented rear wall is positioned behind the jet blast deflector and extends above a discharge lip of the deflecting surface of the jet blast deflector surface. An exit port of the rear vent channel allows airflow moving through the rear vent to exit and combine with the airflow deflected along the jet blast deflecting surface discharge lip. The vent opening in the rear wall is located in the back of the rear noise attenuating wall.
