摘要： A noise abatement system for a large caliber gun includes a gun muffler and a projectile stop, both of which are mounted on a concrete slab. The gun muffler can be coupled at an end to a gun tube of the gun and serves to attenuate pressure waves caused by the firing of a projectile by the gun. The projectile stop is longitudinally aligned with the gun muffler and serves to selectively stop projectiles fired by the gun and to selectively permit projectiles to pass. The projectile stop preferably has an opened first end closest to the gun muffler and a second end to which a door is mounted. When it is desired to aim for a target beyond the projectile stop, the doors are opened to permit the projectile to pass through the projectile stop unhindered. When the projectile stop is used to stop projectiles, the doors are closed and the projectile stop is filled with a particulate material, such as sand.
