the CDNL is less than 62. Noise‐sensitive uses are generally acceptable but
military operations may still be loud enough to be heard, or even judged to be
bothersome on occasion.
A Land Use Planning Zone (LUPZ) is defined for the upper end of Noise Zone I
and includes areas where the CDNL is between 57 and 62 or the ADNL is
between 60 and 65. It does not include land for PK15(met). This zone accounts
for variability in seasonal operations and an increased frequency in operations
during certain times of the year. Noise‐sensitive uses are generally acceptable
within this area; however, this may vary on a case‐by‐case basis.

Small Arms Noise
Due to the training that occurs at FMR, only small arms noise contours have been
modeled. Small arms weapons typically refer to hand‐held and easily portable weapons
of .50 caliber or less that are primarily used against personnel and lightly armored or
unarmored equipment. The Small Arms Range Noise Assessment Model is the computer
program used by the Army to model small arms noise zones. It uses the peak noise level
and incorporates the most up‐to‐date information available on weapons noise source
models, sound propagation, ricochet barriers, noise mitigation and safety structures, and
the direction weapons are fired to create the noise zones.
The noise zones that were modeled for FMR represent a maximum small arms training
scenario where all ranges are actively firing. This event is unlikely to occur due to the
overlap of some ranges and their associated safety zones. However, there are also
individual events where noise generated is louder than the model that is generated
based on an average. Noise Zone III falls entirely within the boundary of FMR. Noise
Zone II extends outside the boundary for approximately 4,000 feet to the east, 2,300 feet
to the south, and 3,700 feet to the west. However, there is currently minimal
development in this area, and there are very few noise‐sensitive uses. The noise zones
are illustrated on Figure 3‐5.
