Parents with children who attend school in congested areas should be aware of the dangers of learning fears.

PARENTS HAVE BEEN WARNED that their children’s brain development will be slowed at schools in noise-polluted areas.

Scientists tested the effects of noise pollution on children’s development in a new study, and the results were shocking.

The Barcelona Institute for Global Health conducted a study comparing children’s cognitive development and noise pollution.

Students learning in louder environments developed slower in terms of attention and working memory, according to the findings.

“The finding suggests that noise peaks inside the classroom may be more disruptive to neurodevelopment than the average decibel level,” said Professor Foraster.

This is significant because it lends support to the hypothesis that noise characteristics can be modified.

Working memory is what we use to store the information we gather while focusing. Attention is the ability to focus on a task for an extended period of time.

Professor Maria Foraster and her colleagues examined 2,680 children aged 7 to 10 from 38 different schools.

During the academic year, each student took four cognitive tests, and the researchers compared the results to the level of noise measured outside the schools and playgrounds.

The experiment concluded that there was a direct relationship between high outdoor noise levels and poorer student performance in all cognitive tests administered throughout the year.

Researchers discovered that a five-decibel increase in outdoor noise level reduced average complex working memory development by just over 23%.
