FICAN conducted a pilot study on the relationship between aircraft noise reduction in schools and standardized test scores. The results suggest that there is a strong relationship between noise reduction in schools and reduced failure rates (i.e., improvement) as measured by state mandated test scores, at the high school level. A summary of the study is provided here:
The European Union has recently published findings of its Road Traffic & Aircraft Noise & Children's Cognition & Health Study, which suggests a relationship between high aircraft noise levels and reduced academic performance.
