    Acoustical Testing Results for SIRRPP — July 2025

    Harris Miller Miller & Hanson Inc. (HMMH) conducted sound insulation measurements at 30 homes near Seattle-Tacoma International Airport in June 2025 to determine whether interior noise levels meet the federal threshold for sound insulation assistance. Using FAA-approved testing methods, the study found that only 3 of the 30 homes had median interior Day-Night Average Sound Levels (DNL) at or above the qualifying 45 dB threshold, while an additional 3 homes had individual rooms exceeding that level. The results inform eligibility decisions under the SEA Repair and Replacement Program, which is governed by FAA Advisory Circular 150/5000-9B and the Airport Improvement Program Handbook.

    StART SIRRPP Update — Acoustic Testing Procedures and DNL Metrics — Slide 12 (February 26, 2025)

    This slide from a Seattle-Tacoma International Airport (SEA) noise remedy presentation summarizes acoustic testing procedures, stating that testing followed the FAA-approved 2017 Acoustic Testing Plan (ATP). Key metrics cited include a 70dB DNL exterior noise contour threshold within the 2014 SEA Noise Remedy Boundary and a 27dB Noise Level Reduction (NLR) example calculated from interior and façade measurements.

    Order 2024-04: Sound Insulation Repair and Replacement Pilot Program

    In February 2024, the Port of Seattle Commission proposed Order 2024-04, directing an assessment of previously installed noise insulation packages to be completed by end of 2024, with findings reported to Commissioners by January 21, 2025. The order also establishes a Sound Insulation Repair and Replacement Pilot Program, backed by an initial $5 million commitment, to identify and fix aging or ineffective insulation in homes near Seattle-Tacoma International Airport. Priority for repairs will be determined using the Port's equity index to ensure underserved communities are considered first.

    Second Chance Initiative Application Form (SC-1): San Francisco International Airport Residential Sound Insulation Program

    The San Francisco International Airport (SFO) Second Chance Noise Insulation Initiative offers free acoustical improvements to eligible residential property owners who previously declined or did not respond to earlier phases of the Noise Insulation Program. To qualify, properties must fall within the 65-decibel CNEL noise contour, have been built before October 1, 1998, and owners must agree to grant a perpetual avigation easement to SFO and the City and County of San Francisco. Eligible improvements may include window and door replacement, caulking, weather-stripping, and central fresh air ventilation installation.

Sea-Tac Airport is currently undergoing the largest and longest expansion in its history, collectively known as the Sustainable Airport Master Plan (SAMP). Some of it you can already hear, but you’re probably not aware of what it all means. Here’s what you need to know.

As the source for federal transportation grants, the Puget Sound Regional Council was charged with developing a system to meet the growing need for commercial aviation. When the search for a second airport failed, they authorized the Port of Seattle to build the Third Runway, with a mandate to develop a noise abatement and mitigation program. In their effort to stop the Third Runway, the ACC argued over every detail of the Port's efforts--including property buyouts and sound insulation. The dispute was meant to be settled by a three member Expert Arbitration Panel. This is their final report. It finds 2-1, that the Port's program was insufficient in several respects. Despite that, funding for the Third Runway was approved by the PSRC, and the 'Port Package' program, proceeded largely unchanged. Expert Arbitration Panel's final decision finding that the Port of Seattle had not shown sufficient reduction in real on-the-ground noise impacts to satisfy noise reduction conditions required for approval of a third runway at Sea-Tac International Airport. The majority decision concluded the Port's noise abatement programs were insufficient despite being impressive in scope.
