  • AAAE National Aviation Environmental Management Conference Steven M. TaberChevalier, Allen & Lichman, LLPAviation NoiseTampa, FloridaFebruary 9-10, 2009

  • IntroductionNoise is highly subjective Try to make it less disagreeable to most peopleThings are getting quieter, but who cares?Two AreasAssessing the ProblemSolutions to the Problem

  • Assessing The ProblemAssessing and Tracking=Three ThingsHow is the noise created?How is the noise transmitted?What is the communitys response to the noise?Recent updatesAssessment and tracking of aircraft noiseUnderstanding the effect of aircraft noise on the community

  • Assessing and Tracking NoiseTwo Updates over the past yearFAA continues development of Aviation Environmental Design Tool (AEDT)Lochard development of WebTrak FlyQuiet

  • AEDT to Be Released in 2011One-Stop Shopping AEDT will replace EDMSINMNIRSInclude the capabilities for national and global analyses.

  • Lochards WebTrak FlyQuiet ProductIdentifies flights that do not comply with airport noise procedures and communicates that information to the airport operator Enables airports to reinforce procedures and improve future complianceAircraft operators can quickly investigate noise and flight track violations themselveshttp://www.lochard.com/content/view/110/20/lang,uk_us/

  • The Effect of Aviation Noise on the Community

    FICAN recommends using ANSI Standard S12.9-2008 to predict Aircraft noise awakeningsNew PARTNER studies focus on annoyance, sleep disturbance, sound transmission

  • FICAN Recommends ANSI Standard S12.9-2008Federal Interagency Committee on Aviation Noise (FICAN) updated its recommendation regarding how to predict people being awakened by aircraft noiseFICAN now recommends the use of ANSI S12.9-2008, Quantities and Procedures for Description and Measurement of Environmental Sound Part 6: Methods for estimation of Awakenings Associated with Outdoor Noise Events Heard in Homes

  • FICAN Recommends ANSI Standard S12.9-2008 (p.2)FICAN: ANSI S12.9-2008 provides a method to predict sleep disturbance in terms of percent awakenings or numbers of people awakened associated with noise levels in terms of indoor A-weighted sound exposure level. See, http://www.fican.org/pdf/Final_Sleep_Dec2008.pdfNew standard enables estimation of awakenings from an entire night of noise events

  • PARTNER StudiesThe Partnership for Air Transportation Noise and Emissions Reduction (PARTNER) An FAA/NASA/Transport Canada sponsored Center of ExcellenceThree projects to assess, model and predict annoyance, sleep disturbance, and sound structural transmissionProject 24, Noise Exposure Response: Annoyance. http://web.mit.edu/aeroastro/partner/projects/project24.htmlProject 25, Noise Exposure Response: Sleep Disturbance http://web.mit.edu/aeroastro/partner/projects/project25.htmlProject 26, Sound Structural Transmission http://web.mit.edu/aeroastro/partner/projects/project26.html

  • Project 24, Noise Exposure Response: AnnoyanceOutgrowth of PARTNER Project No. 2Goal is to develop a deeper understanding how noise affects annoyance in communities in proximity to airports.Looking at the impact of low frequency noise on annoyance level.Will investigate whether knowledge of the noise source influences annoyance.

  • Project 25, Noise Exposure Response: Sleep DisturbanceGoal=understand the impact of aircraft noise on sleep and develop models that predict sleep disturbanceA more robust sleep disturbance modelCoupled with noise prediction tools

  • Project 26, Sound Structural TransmissionDevelopment of numerical models to evaluate the transmission of low frequency noise through windows, doors, walls, and roofsFocus is on residential buildingsWill help manufacturers establish criteria for classifying acoustic performance

  • IntroductionNoise is highly subjective Try to make it less disagreeable to most people Two AreasAssessing the ProblemSolutions to the Problem

  • Solutions to the ProblemTwo aspects of limiting the effect of aviation noiseNoise mitigation, i.e., limiting the population affected by noise and limiting the effect of noise on the populationEffective Community outreach

  • Noise MitigationFour types of noise mitigationLand use compatibility planning and managementNoise abatement operational proceduresNoise reduction at the source (i.e., the aircraft)Aircraft operational restrictions

  • Noise Mitigation Type 1: Land Use Compatibility Planning and ManagementPARTNER Study. Land Use Management and Airport Controls: A Further Study of Trends and Indicators of Incompatible Land Use http://web.mit.edu/aeroastro/partner/reports/proj6/proj6-landmgt-aptcontrol.pdfFunding for noise mitigation.

  • PARTNER Study: Land Use Management and Airport ControlsConcludes that earlier land-use policies may have led to some of todays conflictsMakes three recommendations:A proactive and effective communication link should be established and maintained between, city, county, airport, neighborhood communities, and real estate developersA nationally standardized method of complaint collection and reporting should be designedSuggested that local jurisdictions put in place an ordinance making it mandatory for any individual, city, county or real estate developer to obtain approval from the Airport Director for any substantial structure or zoning change occurring within the immediate vicinity of an airport and under flight paths.

  • Funding for Noise Mitigation$2.86 billion of total PFC revenue devoted to noise mitigation projectsNoise grants (from AIP) totaling $272.7 million awarded to 48 airports in fiscal 2008That funding level is $15.6 million less than the $288.3 in AIP noise mitigation grants awarded to 63 airports in fiscal 2007.

  • AIP Funding For Noise Mitigation 2007-2008

  • Noise Mitigation Type 2: Noise abatement operational proceduresDraft update of Part 150 advisory circular (AC 150/5020-1)

  • Draft AC 150/5020-1 Airport Noise and Land Use Compatibility PlanningSection 7.10 Proposes noise mitigation measures that reduce noise impact beyond the 65 dB DNL contour line. Here is the issue:Airports must demonstrate that the proposed mitigation measure will have a noise benefit Noise benefit=when the number of people located on a noise map is reduced due to a mitigation measure.Most airport noise maps end at the 65 dB DNL contour.

  • Draft AC 150/5020-1 p.2Perplexing issuesBecause CDAs reduce noise impact beyond the 65 DNL contour, the definition of a noise benefit cannot be metIf local jurisdictions adopt more distant contour as the level of significant noise impact then that contour can be used to show a noise benefitMost airports would need to get local jurisdictions to change their planning documents

  • Draft AC 150/5020-1 (p.3)Second Perplexing Issue:The Part 150 and 161 regulations are linkedIf demonstrated noise benefits occur beyond the 65 dB DNL contour line, then airports could more easily impose noise and access restrictions under Part 161FAA does not want to make it any easier to obtain a Part 161 approval

  • Third Type of Noise Mitigation: Noise reduction at source (i.e., the aircraft) Newer aircraft are quieterAirlines continue to retire noisier, less fuel efficient aircraft FAAs Continuous Lower Energy, Emissions, and Noise (CLEEN) technologies initiative

  • Fourth Type of Noise Mitigation: Aircraft Operational Restrictions. Disfavored, but still possibleFAA remains opposed to restricting aircraft as a method to reduce noise. Proposed changes to Burbank/Bob Hope airport

  • Solutions to the ProblemTwo aspects of limiting the effect of aviation noiseNoise mitigation, i.e., limiting the population affected by noise and limiting the effect of noise on the populationEffective Community outreach

  • Effective Community OutreachLand Use Management and Airport Controls: A Further Study of Trends and Indicators of Incompatible Land Use. PARTNER, Sept. 2008. FAA InitiativesPARTNER project to develop a website Development of a guidebook

  • Lawsuits Involving NoiseLawsuits that were resolved this past yearTown of Winthrop v. FAA, No. 07-1953 (1st Cir. July 23, 2008). http://www.ca1.uscourts.gov/pdf.opinions/07-1953-01A.pdf

  • Lawsuits Involving Noise (p.2)Lawsuits that have been filed that may be resolved this yearAirspace Redesign (County of Rockland, NY v. FAA, Case No. 07-1363 (D.C. Circuit))Petitioners Reply Brief due March 6, 2009Oral Argument on May 7, 2009

  • Lawsuits Involving Noise (p.3)Lawsuits that probably will be filed in the near future Ft. Lauderdale, FL Lawsuit will challenge the expansion of the Fort Lauderdale-Hollywood Airport.City of Dania Beach has stated that it intends to file a lawsuitSomerville, MAChallenge to the sharp increase in takeoffs from Runway 33LClaim is that this has generated significant noise levels in the community
