Memorandum from Port of Seattle Study Staff announcing a Technical Advisory Committee meeting for January 20, 1981 to discuss the Sea-Tac noise exposure forecast update.

Minutes from a Technical Advisory Committee meeting on the Sea-Tac Airport Noise Exposure Forecast Update, an approximately $80,000 study partially funded by the FAA and expected to be completed by July 1981. The meeting covered two key study tools — the Integrated Noise Model (INM), a computer program that estimates aircraft noise using Ldn (day-night average sound level) measurements, and the Sea-Tac Noise Monitoring System (NMS). Committee members raised concerns about using averaged noise metrics, debating whether single-event noise levels or a 'misery index' tracking flights above a threshold decibel level would better reflect community impact.
