Insights

Children exposed to higher levels of aircraft and road traffic noise at school made more errors on complex cognitive tasks. Simple tasks were less affected by noise, indicating noise impacts more demanding cognitive functions.

Area of Science:

  • Environmental Psychology
  • Cognitive Neuroscience
  • Child Development

Background:

  • Limited research exists on noise exposure and children's cognitive performance.
  • Previous studies lacked source-specific exposure-effect relationships for noise impacts.

Purpose of the Study:

  • Investigate the effects of aircraft and road traffic noise on primary schoolchildren's cognitive performance.
  • Examine noise impacts in both home and school environments.

Main Methods:

  • 553 children (9-11 years) from 24 schools near Schiphol Amsterdam Airport participated.
  • Cognitive performance assessed using the Neurobehavioral Evaluation System (NES) and paper-and-pencil tests.
  • Multilevel regression analyses controlled for demographic and school-related confounders.

Main Results:

  • Higher school noise levels (road and aircraft) correlated with increased errors on difficult parts of the Switching Attention Test (SAT).
  • Strong coherence observed between neurobehavioral and paper-and-pencil test results.
  • Noise exposure significantly affected performance on more complex cognitive tasks.

Conclusions:

  • Cognitive performance on complex tasks is more susceptible to noise pollution than simple tasks.
  • Noise at school negatively impacts children's cognitive functioning, particularly on demanding tasks.
  • Findings highlight the importance of managing noise environments for optimal child cognitive development.
