Noise created through military operations is
consistently one of the most common nuisances
military bases impose upon the neighboring
communities. Because of this, noise contours
were created in the Seymour Johnson AFB
2011 AICUZ study that illustrate the areas near
the base that are impacted by noise from the
base’s military operations. The noise contours
for Seymour Johnson AFB are depicted on
Figure 11.

The city of Goldsboro is the municipality that is
affected by noise the most. There is a small
area southwest of Seymour Johnson AFB that is
located within the 85 Day‐Night Average Sound
Level (DNL) noise contour, which sounds like the
equivalent of a diesel truck driving from 50 feet
away. This is the area that experiences the
loudest noise from Seymour Johnson AFB
military operations. Most other areas of
Goldsboro, both north and south of the
installation, are located within the 65 DNL and
70 DNL noise contours, which are equivalent to
a regular conversation being held with someone
five feet away.
