Noise may not make kids dumb, but it does make it hard for them to learn. The Road Traffic and Aircraft Noise Exposure and Children’s Cognition and Health (RANCH) project is a multinational study designed to assess the relationships among road and aircraft traffic noise and reading comprehension. Included in its 2006 findings are data from more than 2,000 kids ages 9 and 10, enrolled in 89 schools near airports in three European cities. The verdict: A direct relationship exists between aircraft noise exposure at schools and problems with reading comprehension, even after the investigators account for socio-demographic factors known to interact with reading comprehension.
