The operative claimChronic environmental-noise exposure, particularly aircraft noise around schools, is associated with poorer reading comprehension and long-term memory in children.
A broad evidence base supports a narrow association between chronic aircraft noise at school and poorer reading, with some support for long-term memory; one relevant prospective follow-up was null on its primary group comparison.
The clearest evidence concerns chronic aircraft noise and school-age reading or long-term memory. Evidence for attention, executive function, other cognitive domains, road traffic, and other noise sources is weaker or less consistent.

Systematic review · school age
The review found moderate-quality evidence for associations between aircraft noise and poorer reading comprehension and long-term memory; other cognitive domains and noise sources were less consistent.
Bearing on this claim: Systematic review directly supports the narrowed aircraft-noise, reading, and long-term-memory proposition.

Cross-sectional · school age
Chronic aircraft noise was associated with poorer reading comprehension across countries; the study did not support the same cognitive conclusion for road-traffic noise.
Bearing on this claim: Cross-national RANCH study supports an aircraft-noise and reading association while distinguishing road-traffic noise.

Longitudinal · childhood into adolescence
Aircraft-noise exposure at primary school may have impaired later reading comprehension and increased annoyance, but no significant psychological-health effect was found.
Bearing on this claim: Six-year RANCH follow-up supports possible persistence for reading but not psychological health.

Longitudinal · N = 732 · mean ages 11.1-13.1 years
The follow-up found no significant group effect on reading comprehension across testing periods, although the authors cautiously suggested that earlier exposure might have lasting effects; home language significantly predicted reading.
Bearing on this claim: South African prospective follow-up found no significant group effect on reading across testing periods and is retained as relevant counterevidence.

Meta-analytic heterogeneity is high; reviews and primary-study reports overlap; RANCH appears in multiple publications; and findings are weaker or inconsistent for non-aircraft sources, attention, executive function, psychological health, and other cognitive domains.
Last reviewed August 19, 2026
The review associated elevated classroom and external transportation noise with greater processing load and poorer attention, verbal memory, and reading performance.
Bearing on this claim: Systematic review adds classroom and environmental-noise evidence while retaining domain-specific limits.

Meta-analysis · children and adolescents
Across 152 effect sizes, noise had a moderate negative association with cognitive and academic performance, especially at ages 6-12; heterogeneity across noise types and study designs was high.
Bearing on this claim: Meta-analysis supports a moderate negative relationship between noise and learning while documenting high heterogeneity.

Longitudinal · N = 275 · ages 8-11
At one-year follow-up, chronic aircraft-noise exposure was associated with poorer reading comprehension and sustained attention after adjustment; reading and annoyance effects did not habituate.
Bearing on this claim: Repeated-measures Heathrow study supports poorer reading after adjustment and finds no habituation over one year.

Meta-analysis · school age
Aircraft noise at school was associated with lower reading scores and greater odds of below-average reading performance, but not with emotional symptoms, conduct problems, or total difficulties.
Bearing on this claim: Focused meta-analysis supports lower reading performance with school aircraft noise but not broader psychological difficulties.

Meta-analysis · children and adults
The review found moderate evidence that aircraft noise adversely affects reading and language outcomes in children; evidence and quality varied by population and cognitive domain.
Bearing on this claim: Updated synthesis finds moderate evidence for aircraft-noise effects on children's reading and language.

Longitudinal · N = 326 · mean age 10.4 years
Across three waves, new aircraft-noise exposure impaired long-term memory and reading, while reading and short-term memory improved after the old airport closed.
Bearing on this claim: Prospective airport opening-and-closure study supports changes in reading and memory with changes in exposure.
