A 1972 University of Washington environmental health report examines the serious physical and psychological effects of aircraft noise on residents living near Seattle-Tacoma Airport. On-site measurements recorded up to 95 dBA indoors, with hundreds of daily flyovers exceeding 75 dBA—levels shown by research to disrupt sleep, impair children's school performance, and pose long-term mental and physical health risks. The report also highlights how excessive ambient noise in nearby schools interferes with speech comprehension and the learning process.Open full document
