Noise Exposure Maps
On Feb. 4, 2013, the Federal Aviation Administration (FAA) issued a notice of determination that Nashville International Airport's Noise Exposure Maps for Existing (2012) Conditions and Future (2017) Conditions meet all applicable regulatory requirements.
The notice of the FAA's determination was published in the Feb. 12, 2013 Federal Register (Volume 78, Number 29, page 9988). Use the following link to view an Adobe PDF version of the Federal Register announcement: Federal Register Notice.
The draft document was made available for a 30-day public comment period from November 1 – November 30, 2012. One public comment was received during the comment period. A copy of this comment was incorporated into the final document and submitted to the FAA for review in December of 2012. On Feb. 4, 2013, the FAA issued a notice of determination that Nashville International Airport’s Noise Exposure Maps for Existing (2012) Conditions and Future (2017) Conditions met all applicable regulatory requirements.
The Noise Exposure Map Update report contains Existing (2012) and Future (2017) Noise Exposure Maps (NEMs) and accompanying documentation for Nashville International Airport.

An airport's noise environment is defined and illustrated by the Day-Night Average A-Weighted Sound Level metric known as DNL. The DNL was introduced by the U.S. Environmental Protection Agency (EPA) as a method for predicting the effects on a population of the long-term exposure to environmental noise. The DNL metric is required under 14 CFR Part 150 as the single system for measuring aircraft noise impact and for determining land-use compatibility.
NEMs (sometimes called "noise contours" or "noise contour maps") do not illustrate flight paths. They simply illustrate where most of the aircraft noise is. The number of aircraft heard and the noise level on any given day will depend on which runways are used, weather, flight schedules and community background noise. Aircraft altitudes will depend upon the type of aircraft and the destination or origin of the flight.
NEMs typically depict the DNL 65dB contour, as this is generally identified by federal guidelines as the threshold of significance for aviation noise and other sources of community noise. In general, most land uses are considered to be compatible with DNLs of less than 65 dB.
Nashville's NEMs were generated through use of the Federal Aviation Administration's computerized Integrated Noise Model (INM), which determines the aircraft sound levels associated with an average annual day's activity.
