DEN 3rd Quarter 2006 Noise Report
October 31, 2006 Denver International Airport Noise Office
Third Quarter 2006 News
The number of potential Class II NEPS violations registered during the third
quarter of 2006 is two. During the third quarter 2005, there were five potential
Class II NEPS violation. Please see page six for DEN NEPS information.
Inside this issue: There was no potential 65 DNL noise contour violation for the quarter. The 65
DNL contour continued to be completely contained within the boundaries of the
ANOMS System 2 City and County of Denver. Please see page five for DEN contour map.
There were 66% fewer noise complaints received during this quarter, as corn-
Hotline Policy 3 pared to the second quarter of 2005 (265 vs. 776 in 2005).
The number of households registering at least one complaint increased by 1%
NEPS and RMT map 4 (83 vs. 81 in 2005). Five households registered a combined 36% of total com-
plaints.

DEN Airport Noise and Operations System
•
The DEN Airport Noise and Operations Monitoring System (ANOMS) is a
state-of-the-art computer system designed to enable the City and County of
Denver to monitor aircraft noise in the vicinity of the airport. In addition to
monitoring noise levels, the system calculates Noise Exposure Performance
Standards. (NEPS) at 101 grid points in Adams County (see map on page 4
for NEPS locations).
The DEN ANOMS system monitors noise levels at 27 permanent and 4
portable noise monitoring terminals. These terminals are located through-
out the Denver metro area (see map on page 4 for RMT locations).
The system also records the movement of all aircraft in the vicinity of
'`• t: .k DEN by utilizing FAA air traffic control radar data. This makes it possible to
Remote Monitoring match actual flights with noise events.
Terminal (RMT)with In addition, the ANOMS system records weather information from three
a weather collecting Y
station. remote stations, which include a RACAL recording device to record pilot/
controller radio transmissions.
ARTSMAP
ARTSMAP is a specially designed noise modeling program that automatically
creates noise contours. ARTSMAP is designed to create contours from actual ra- tt
dar flight tracks that our office receives from the FAA ARTS system which is sent
via modem, eliminating the need for manual data manipulation. The ARTSMAP
software is installed on a computer in the Noise Abatement Office. The program
analyzes, views, reports, and stores the data. Currently, ARTSMAP is used at sev-
eral major airports nationally. It allows the DEN Noise Abatement Office to per-
form noise data analysis, generate daily automated noise contours, receive de-
tailed runway utilization, and airline fleet mix identification. DENto terminal

Land Use and Zoning
Urban growth and development in the areas surrounding DEN, particularly non-
compatible residential and other noise-sensitive land uses, is of utmost concern to
the City and County of Denver. The Noise Office has developed noise contours
surrounding the airport, inside which certain types of land uses are not recom-
mended. The 65 Ldn noise contour (average decibel level with a 10 decibel pen-
alty applied to nighttime operations) is a line inside
which, under Federal guidelines, no residential develop-
ment should occur.
The operational 65 Ldn noise contour for the air
port, as created by ARTSMAP, is included in this report.
However, for DEN, the 60 Ldn noise contour is used for
compatible land use planning by the surrounding juris-
dictions, in accordance with guidelines promulgated by
the Denver Regional Council of Governments and the
Denver/Adams County Intergovernmental Agree- s '
ment. Additional mapping for DEN that includes the --
applicable noise contours is available upon request. wt.acamm:.thb M contours roc Land u..Triomf

DEN Noise Hotline Policy
The purpose of the DEN Noise Complaint Hotline is to provide an opportunity for individuals to express
their concerns regarding noise generated by aircraft operating at DEN. Citizens are asked to leave their
name, address and the date and time of their complaint on the hotline. Complaints are downloaded daily
by our Noise Analysts and then transcribed into the ANOMS system, where specific complaints can be
matched to individual flight tracks. It is essential for all information to be entered correctly in order for
the system to be effective.
Profanity will not be tolerated, and will result in the complaint not being
registered. Any attempt to deliberately tie-up or abuse the Hotline may result
in police action. Phone harassment is a state criminal offense and can carry a iFilv
jail sentence and/or fine. Threats involving aircraft and/or the airport are a
very serious matter and are a federal criminal offense. To make a threat, even a y.�
jokingly, will result in a notification to the Denver Police Department and may
involve an FBI investigation. p .

Glossary Of Terms
Sound: A rapid variation in air pressure, which is perceived by the ear and brain as sound.
Noise: Generally considered to be any sound, which is deemed undesirable by an individual.
Decibel: Sound is measured by its pressure or energy in terms of decibels. The decibel scale is logarith-
mic; when the decibel level increases by 6 dB, the measured sound is twice as loud.
Noise Abatement: A measure or action that minimizes the amount or impact of noise on the environs of
an airport. Noise abatement measures include aircraft operating procedures and use or disuse of certain
runways or flight tracks. These operating procedures are controlled by the FAA.
A-Weighted Sound Level (dBA): A type of sound level measurement which reduces the effect of very
high and very low frequencies in order to mimic the response of the human ear. Nearly all aircraft sound
level measurement is conducted using A-weighting.
Equivalent Continuous Sound Level (Leq): A measurement of the average sound energy experienced
over a period of time. This average sound level is expressed in decibels, and includes a notation of the
period of time, which it covers (such as Leq (24) for an average of the sound level over a 24-hour period).
Day Night Level (Ldn): Also referred to as DNL. Similar to a Leq measurement, but is conducted over at
least a 24-hour time span and includes a 10dB nighttime penalty. For an Ldn calculation, all noise that
occurs at night (defined as 10:00 pm to 7:00 am) is artificially increased for the public's increased sensi-
tivity to noise during these hours.
Noise Contour: A line surrounding an airport that encloses a geographic region, which is exposed to a
particular Ldn level. These contour lines are nested in such a way that contours closer to the airport gen-
erally surround areas that experience higher noise levels than contours farther out. Annual Ldn contours
are used to determine whether certain types of zoning or land uses are compatible with particular annual
Ldn noise levels. 65 Ldn is considered by many federal agencies to be the level at which residential land
use becomes incompatible.
Remote Monitoring Terminal (RMT): Consists of a noise level analyzer, a weatherproof microphone, a
system controller, a power supply, and a dedicated telephone line to download noise data to the ANOMS
system, all mounted in a weatherproof cabinet.
