This paper uses the Boston Logan Airport Noise Study (BLANS) as a case study to explore howthe combined use of supplemental noise metrics, a Noise Analysis Protocol, and supplementaltools can help the authorities, communities, and consultants work together. The BLANS is amulti-phase effort to reduce noise impacts in the communities surrounding Boston LoganInternational Airport. The partners in this study are the Federal Aviation Administration (FAA),the Massachusetts Port Authority (MassPort), and the Community Advisory Committee (CAC).Phase 1, which was completed in early 2007, assessed flight tracks over a study area extendingfar beyond the airport’s 65 DNL contour. In addition to DNL, supplemental metrics were usedby the CAC to review and select preferred noise abatement procedures. Phase 2, which is nowunderway, began with a group consensus on the Aircraft Noise Analysis Protocol. The chiefelements of the Protocol include explanations of model accuracy and limitations; descriptions ofnoise models and tools to be used; model input data requirements; definitions of metrics; andcomparisons of noise model results to field measurements. The benefits of the Protocol are thatall stakeholders contributed and were thus informed about the details of the technical processbefore the analysis began.
