The Draft Environmental Impact Statement for the OLF will include a comprehensive noise study, to include both Day-Night Average Noise Levels (DNL) and Sound Exposure Levels (SEL). DNL is the commonly accepted method for measuring noise impacts to a community, and is used by the FAA to measure noise impacts around commercial airports. SEL refers to the noise experienced as a single event. The best available noise data and the most advanced noise modeling technology will be used to model noise impacts for inclusion in the EIS. Actual noise levels depend upon numerous factors such as local terrain conditions, altitude, engine settings, speed, flight duration and others. Only a comprehensive noise study such as that to be provided in the EIS can accurately depict anticipated noise levels. A fighter jet sound level is approximately 110 – 115 dBA on take-off. For comparison an ambulance siren is 100 dBA, a vacuum cleaner is 70 dBA, normal conversation is 60 dBA, and a quiet urban nighttime
