If you have any questions regarding these reports, or if I can be of further assistance, please contact me at (303) 342-2360. Sincerely, Andrea C. Christensen Denver International Airport Aviation Noise Analyst DENVER INTERNATIONAL AIRPORT Department of Aviation Airport Office Building 8500 Pena Boulevard Denver,Colorado 80249 303.342.2200 www.FlyDenveccom C ONsr Att p4 cc : 11 1- 05--,242 cq296, — /R?9 DEN 1St Quarter 2006 Noise Report May 1, 2006 Denver International Airport Noise Office First Quarter 2006 News The number of potential Class II NEPS violations registered during the first quarter of 2006 was zero. During the first quarter 2005, there were zero po- tential Class II NEPS violations. Please see page six for 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 ANOMS System z the City and County of Denver. Please see page five for DEN contour map. There were 75% fewer noise complaints received during the quarter, as Hotline Policy 3 compared to the first quarter of 2005 (1 26 vs. 506 in 2005). The number of households registering at least one complaint decreased by NEPS and RMT map 4 28% (33 vs. 46 in 2005). Four households registered a combined 48% of total complaints. 1st Quarter Contour S .., .� Please see pages seven and eight for complaint and operational statis Din's Jeppesen Tarminkl at dusk. r NEPS Table 6 tics.

However, a home • Complaint map, page B. near a major airport may not be a good solution for everyone. This guide will inform people of the noise issues they may face by purchasing property near DIA. It will also inform homeowners about future development at the airport and how they may be impacted by such development. Denver Noise Office -Denver International Airport-Airport Office Building- 8500 Pena Boulevard-Denver, CO 80249 DEN 1st Quarter Noise Report 2006 May 1,2006 Page 2 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 3 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 3 for RMT locations). .111111111 The system also records the movement of all aircraft in the vicinity of 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- 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 .. 'x. 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. DENtent s Terminal t roof view from the South. 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 F 7 the Denver Regional Council of Governments and the �• Denver/Adams County Intergovernmental Agree- ment. Additional mapping for DEN that includes the --- applicable licable noise contours is available upon request. DEN Recommend Noise Contours for us us.manning DEN 1st Quarter Noise Report 2006 May 1,2006 Page 3 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 jail sentence and/or fine. Threats involving aircraft and/or the airport are a VtAlin,.r,,- very serious matter and are a federal criminal offense. To make a threat, even "'". jokingly, will result in a notification to the Denver Police Department and may involve an FBI investigation. "ft"a -a"--ti T TT`rrf DEN Arrival 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.
