    Ground Noise Study Progress Update

    • Sound level decreases by 6 dB per doubling of distance • Additional losses due to atmospheric absorption Ground Effect: • Sound levels are lower when reflected off of soft ground vs. hard ground Sound Propagation Refraction due to Temperature: • Gradients in temperature cause the bending of sound paths • Sound bends upward during a temperature lapse (cool air over warm) • Sound bends downward during a temperature inversion (warm air over cool) Sound Propagation Refraction due to Wind: • Gradients in wind speed cause the bending of sound paths • Sound bends upward causing sound shadows in the upwind direction • Sound bends downward increasing sound levels in the downwind direction • Differences between upwind and downwind directions can be 20 dB Scope of Services ✓Ground Noise Data Research • Meet with StART • Identify ground noise sources and locations • Identify atmospheric conditions that may increase ground noise • Noise Monitoring (in progress – data acquisition complete) • Obtain and analyze data from permanent monitors • Collect and analyze additional temporary noise monitoring data • Identify Mitigation Options • Present findings on ground noise sources and levels and solicit input on mitigation measures • May include changes in aircraft operating procedures or utilization of new or existing structures to reduce community noise exposure • Report Project Results Noise Measurement Locations • Site 1: Northeast • Taxiing/queueing • Start-of-takeoff roll • Engine run-ups • Site 2: East • Terminal din • Auxiliary Power Units (APU) and taxi •…
