Aircraft Noise Measurement and Modeling

Community exposure to aircraft noise can be both measured and modeled. Modeling (i.e., prediction) of noise exposure is unavoidable in prospective applications, such as disclosure of the impacts of proposed airport infrastructure construction, since noise that has not yet been created cannot be directly measured. Measurement is more useful for retrospective purposes, such as monitoring and reporting of noise created by ongoing airport operations, and also for aircraft noise certification, per FAR Part 36.
