2025-02-26StART SIRRPP Update: Interior DNL Eligibility Threshold and Acoustic Testing Results — Slide 14 (February 26, 2025)
Slide 14 of a presentation on acoustic testing for a Sea-Tac Airport noise insulation program, explaining that interior DNL (calculated as Exterior DNL minus Noise Level Reduction) is the eligibility metric, with a threshold of 45dB DNL. All 30 homes tested fell below the FAA's 45dB DNL interior noise threshold, including five Pre-1993 homes evaluated under the FAA re-insulation program. -

2025-01-14Aviation Impacted Communities Act: Fact Sheet
The Aviation Impacted Communities Act, introduced by Rep. Adam Smith (WA-09), aims to give residents and local leaders a stronger voice in addressing excessive airplane noise and environmental impacts by requiring the FAA to engage directly with affected communities through newly established community boards. The bill would create an 'aviation impacted communities' designation, allow communities to petition for comprehensive impact studies, and expand funding for noise mitigation beyond current sound-level boundaries. It also establishes a sustainable revenue stream for ongoing relief efforts through the Airport and Airways Trust Fund. -

2025-01-07Aviation-Impacted Communities Act: House Bill Text (119th Congress, 1st Session)
The Aviation-Impacted Communities Act, introduced in the 119th Congress by Rep. Smith of Washington, would require the FAA to provide noise mitigation funding to communities affected by airport noise even if they fall outside the current 65 DNL sound threshold. The bill would make these communities eligible for Airport Improvement Program funds, allow them to establish local boards to address airport noise, and direct the National Academy of Sciences to study aviation impacts at major hub airports — including King County, WA (Sea-Tac) — across the country. -
