- The research evidence suggests that chronic exposure to noise affects cognitive functions involving central processing and language comprehension.

- Noise-exposed children have difficulties in concentrating in comparison with children from quieter school.

- Children exposed to chronic environmental noise have been found to have poorer auditory discrimination, speech perception,  poor reading ability and poorer memory requiring high processing demands.

Cognition

In the Los Angeles Airport Study, chronic exposure to aircraft noise was found to be associated with raised systolic and diastolic blood pressure.

Cardiovascular effects

In the cross-sectional study at the old airport, endocrine levels were significantly higher in the noise-exposed children, indicating raised stress levels. 

Endocrine disturbance

In London, child-adapted, standard self-report questions48,80 were used to assess annoyance and showed higher annoyance levels in noise-exposed children.

Noise annoyance

  In the Los Angeles Airport Study, children exposed to chronic aircraft noise were less likely to solve a difficult puzzle involving a success or failure experience and were more likely to give up.
