    Response to comments on the Sea-Tac/Communities Plan Draft Environmental Impact Statement

    This document is a formal response to public comments on the Sea-Tac/Communities Plan Draft Environmental Impact Statement, addressing concerns about the airport's Noise Remedy Program. It explains that noise program classifications for petition signers were upgraded due to factors such as summer flight patterns and proximity to approach paths, and that most signers were moved into the Purchase Guarantee area or recommended for the Cost Sharing Insulation Program. The response also notes that no specific schedule exists for noise remedy implementation due to uncertainties in federal funding, and that detailed land-use planning for acquisition areas will involve full citizen participation after properties are acquired.
  • Acoustic Weighting Curves 100Hz Red Arrow

    A standard audio engineering graph showing the frequency response curves for A-weighting (blue), B-weighting (yellow), C-weighting (red), and D-weighting (black) filters, plotted as Gain in dB versus frequency from 10 Hz to 100 kHz. A red arrow highlights the low-frequency region (~50-80 Hz) where the curves diverge most significantly, particularly relevant to aircraft noise assessment where D-weighting was developed specifically for aircraft noise measurement.
