QUOTE : One study found that the reading scores of students in a New York City elementary school were significantly lower if their classrooms were situated close to elevated subway tracks on which trains rattled past every four to five minutes. When the researchers, armed with their findings, pressed NYC transit system officials and Board of Education members to install noise-dampening materials on the tracks and in the classrooms, students’ scores jumped back up. Similar results have been found for children near airplane flight paths. When the city of Munich, Germany, moved its airport, the memory and reading scores of children near the new location plummeted, while those near the old location rose significantly.
