Have you ever wondered the impact noise can have on our cognitive ability? Psychologist Arlene Bronzaft was curious to find out. Studying Public School 98 on the northern tip of Manhattan, Bronzaft found that children who were assigned to classrooms on the side of the school facing above-ground train tracks were on average, 11 months behind their counterparts on the quieter side of the school building.
After these findings were presented, the New York City Transit authority installed noise-abatement equipment on the tracks, and follow-up studies found no significant difference between the two groups.
