本航空航天推荐规程（ARP）提供了两种测量建筑物正面飞机噪声级降低的方法。机场及其顾问可以使用本ARP中提出的任何一种方法来确定暴露于飞机噪声中的结构是否有资格参与FAA资助的机场噪声缓解项目，确定满足项目目标所需的处理方法，并验证这些目标是否得到满足。

This Aerospace Recommended Practice (ARP) provides two methods for measuring the aircraft noise level reduction of building fa¿¿ades. Airports and their consultants can use either of the methods presented in this ARP to determine the eligibility of structures exposed to aircraft noise to participate in an FAA-funded Airport Noise Mitigation Project, to determine the treatments required to meet project objectives, and to verify that such objectives are satisfied.
