The Process

The 14 CFR Part 150 Noise Study is a formal process for addressing airport noise and noncompatible land uses. The following are the key steps involved in the Study process:

  1. Identification of Issues: Identify airport noise and land use issues and incompatibilities.
  2. Noise Exposure Map (NEM) Report: Create a report showing existing (year 2019) and future (2024) aircraft sound exposure levels.
  3. Noise Compatibility Program (NCP): Recommend measures to address aircraft noise, such as sound insulation, zoning changes, and alterations in aircraft operations. FAA-approved measures may be eligible for federal funding.
  4. DNL (Day-Night Average Sound Level): Quantify noise exposure over a 24-hour period using DNL, which averages sound levels and accounts for nighttime weighting.
