          - Changed from S8 to N1
          - Collaborative effort among ARP, AEE and Tech Center
          -  Began with Community Noise Survey in FY12
          - Three survey follow-on were funded with FY 16 and started in Fy17, wrapping up within the next few months. 
          - 5 new Noise Research Requests 
          - N2.1 postponed – FY18/FY19?

RPA N1 – Noise ProgramsN1.1 National Noise Survey
        - Information regarding survey results will be disseminated appropriately and include:
        - New aviation-only Dose Response Curve
        - Supporting Materials
        - FAA will review dose-response curve and determine what, if any, actions, policy, or guidance will be needed
        - FAA internal policy research and review programs have been initiated
        - FAA will coordinate with other Federal Agencies, including coordination through the Federal Interagency Committee on Aviation Noise (FICAN), regarding survey results
        - A public review and comment process will occur prior to making any policy determinations

RPA N1 – Noise ProgramsN1.2 - 1.4 Research on Potential Policy Implications of Noise Survey
        - NEPA significant impact criteria review
        - Developing options for possible noise significance criteria and comparing their application under alternative dose-response relationships
        - Considerations for land use compatibility also being reviewed
        - Sound insulation efficacy for alternative eligibility criteria
        - Evaluating effectiveness of standard sound insulation treatments over range of alternative eligibility criteria
        - Alternative mitigation options for noise levels below 65dB DNL
        - Considering alternative mitigation options to standard sound insulation treatments

Each research project will yield “possibility” menus to inform policy makers as they consider results from noise annoyance survey

RPA N1 – Noise ProgramsN1.5 National Survey Phone Analysis
        - Using phone data collected, research WHY people are more or less annoyed by aircraft noise.
        - 2,328 phone interviews
        - Develop analysis plan to determine what additional information can be identified regarding annoyance responses and people’s experiences. 
        - Same research team
        - 12 month effort
