Aircraft Noise Monitoring at Denver International Airportby Andrew S. Harris, Harris Miller Miller & Hanson, Inc, Lexington, United States,
Abstract: This paper describes design of the noise monitoring system for Denver International Airport. When the airport opens in 1993, the system must monitor compliance with two standards established by the Intergovernmental Agreement that allowed Denver to annex the land required for the airport. The system will monitor: (1) the location of the contour for an Ldn of 65 dBA; and (2) noise exposure at an additional 100 points where the 24-hour Leq from aircraft will be in the range from 34 dB to 52 dB. Because the Intergovernmental Agreement calls for severe monetary penalties if the levels exceed the standards, it is essential that the system not identify any non-aircraft noise as coming from aircraft sources. The system design employs two microphones for each monitoring point to allow positive identification of noise from aircraft and elimination of noise from non-aircraft sources.
