28 4 Practices and Guidelines for Using Spatiotemporal Population Data with Aviation Noise Studies 4.1 Introduction A crucial part of this research was to identify the elements of aviation noise study practices that will be affected by the introduction of spatiotemporal population data. We examined the applicability of spatiotemporal population data, limitations of the approach, and further research needs.

30 4.5 Types of Aviation Noise Studies 4.5.1 NEPA Studies Noise impact studies typically come under the requirements of NEPA as implemented in FAA Order 1050.1F, Environmental Impacts: Policies and Procedures, and its associated Desk Reference. According to NEPA, major federal actions that have the potential to affect the environment are subject to environmental review.
