1 Environmental Affairs Seminar Noise Briefing April 15, 2010 Dan Frazee, San Diego County Regional Airport Authority Mary Ellen Eagan, HMMH

2 Topics CAEP PARTNER ACRP FAA Environmental Noise Policy FAA Noise Research Roadmap Modeling UC Davis Noise & Air Quality Symposium Summary

3 ICAO Committee on Aviation Environmental Protection CAEP/8: Approved evaluation of possible new noise stringency options for discussion at CAEP/9 (2013) Will look at brackets that range from -3 db to -12 db (relative to current Stage 4 standard) Phase-out of Stage 3 aircraft will not be addressed Driven be EU needs (esp UK) Work begins in June

4 Partnership for AiR Transportation Noise and Emissions Reduction (PARTNER) Project Objective Status 1. Low Frequency Noise Study 2. Source Emission and Propagation 8. Sonic Boom Mitigation Evaluated the perceptual impact of low frequency aircraft noise Provide a better understanding of aviation noise problems and contribute to the development of improved noise impact prediction tools Determine if sufficient new data exists to warrant a reevaluation of the FAA s regulation prohibiting supersonic flight over land Final report complete Enhanced propagation study complete; work continuing on en route propagation, sonic boom reflectivity. Listening environment testing complete, pilot study comparing physiological and subjective measures of startle conducted.

5 Partnership for AiR Transportation Noise and Emissions Reduction (PARTNER) - continued Project Objective Status 10. Outreach Provide educational information on aviation noise 19. Health Effects of Noise 24. Noise Exposure Response - Annoyance 25. Noise Exposure Response: Sleep Disturbance Quantify the impact of noise accurately for CBA. Develop a deeper understanding of how noise affects annoyance in communities in proximity to airports Understand the impact of aircraft noise on sleep, and to develop models that predict sleep disruption Ongoing. See NOISEQUEST Examined sharpness, tonalness, roughness, and fluctuation strength. Evaluating Number Events metrics. Comparing sleep disturbance metrics: awakenings vs. Lnight.

6 Partnership for AiR Transportation Noise and Emissions Reduction (PARTNER) - continued Project Objective Status 26. Sound Structural Transmission 35. Open Rotor Noise Impact On Airport Communities Develop numerical models to evaluate the transmission of low frequency noise (LFN) through elastic panels such as windows, doors, walls and roofs Assess a large set of metrics to evaluate turbofan and open rotor engines Developing tools for assessing, modeling and predicting LFN propagation through windows under various mounting conditions. Comparing SEL v. EPNdB for evaluating annoyance to open rotor.

9 FAA Revised Draft Environmental Policy: Noise Community noise is the primary environmental concern that can undermine efforts to increase airport capacity. Land uses are considered compatible with airport operations in areas where the annual average aircraft noise exposure is below 65 dba DNL. NextGen noise policy, airport compatibility guidelines, environmental significance thresholds, and mitigation solutions will need to be based on advanced scientific understanding of the public health and welfare impacts of aviation noise using measures of noise exposure that correlate best with such impacts, and based on understanding how non-acoustic factors within control of stakeholders can improve community response / reaction to aircraft operations.

10 FAA Revised Draft Environmental Policy: Noise In summary, the FAA s noise goal is to reduce the number of people residing in areas of significant noise exposure around U.S. airports. As stated above, DNL is the FAA s recommended metric for quantifying cumulative exposure of individuals to noise. Through research, FAA will continue to explore ways to reduce aircraft noise impacts on people.

11 FAA Noise Research Roadmap Motivation: update FAA policy Goal: Identify actionable hypotheses for additional research Outreach Process: stakeholder meetings Status: finishing report ACI-NA input: Members at 3rd workshop sent clear message that noise outside DNL 65 is still a major issue, and there are serious policy implications for changing land use compatibility threshold to DNL 60.

12 Modeling: AEDT Status First Beta release Spring 2010 Focuses on regional capabilities (NIRS) DRG will evaluate Public release late 2011 (?) Tool assessment Uncertainties Real-world comparisons Future investments ACI members should start thinking about integration

13 UC Davis Noise & Air Quality Symposium Summary Noise Beyond 65 Non-acoustic measures Land use compatibility Is it time to advocate for changes to Part 150? Looking for stronger role from airports in 2011 an opportunity for ACI
