A study tracking 326 schoolchildren around Munich's old and new airports found that exposure to aircraft noise impaired children's reading and long-term memory, while children who were relieved of noise when the old airport closed showed improvements in those same areas. Researchers tested the children before and after the airports switched operations, carefully matching noise-exposed and non-exposed groups by socioeconomic background. The findings suggest that aircraft noise has measurable, but potentially reversible, effects on key cognitive skills in school-age children.

A 1997 Cornell University study found that elementary school children chronically exposed to aircraft noise showed significant reading deficits, even when tested under quiet conditions — meaning the harm stems from long-term exposure, not just momentary distraction. The researchers identified impaired language acquisition, particularly speech perception, as a key reason why noise-exposed children fall behind in reading. These findings have direct relevance for communities near busy airports, where sustained noise levels may quietly undermine children's academic development.

A 1992 position statement argues that Seattle-Tacoma International Airport (Sea-Tac) has reached its operational, economic, and environmental capacity and should be capped at a maximum of 380,000 operations per year with no third runway authorized. The document contends that noise impacts on surrounding communities are severely underestimated, that a third runway would make no operational or economic sense, and that alternatives such as demand management, use of existing regional airports, and improved transportation systems should be pursued instead.

A 1975 study by Bronzaft and McCarthy examined how noise from passing elevated subway trains affected the reading ability of elementary school children at a New York City school located approximately 220 feet from the tracks. Researchers compared reading scores of students in classrooms on the noisy train-facing side of the building versus the quieter opposite side, finding that chronic exposure to loud, unpredictable noise was associated with measurable reading deficits. The findings built on earlier research suggesting that children in high-noise environments struggle to distinguish relevant speech cues, which can hinder their ability to learn to read.

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.
