A sound-proofing installation for testing aircraft engines (34) has a sound-proofing wall (1) which consists of a partially circular, fixed section (2) and of at least one partially circular door (3, 4) which can be moved concentrically to the common vertical central axis (11). A parking place for an aircraft (27) is designed as a rotary table (17) which can rotate around the central axis (11). An exhaust jet deflecting fence (13) which can also be moved concentrically to the central axis (11) is provided between the rotary table (17) and the sound-proofing wall (1).
