Have you heard of the term ‘white noise’?

This may sound strange! But latest research has come out with certain findings that prompt us to sit up and take notice. Stacey Singer reports at Plasmid: Science and bio tech blog, that some mild back ground noise is good for Learning Disabled students if they have ADHD.

“Studies published in the October issue of Psychological Review and the August issue of the Journal of Child Psychology and Psychiatry suggest that background noise does help some of us to think: Specifically, those with below-average IQs and those with ADHD.

Both concentration and memory improved in school children with ADHD when white-noise recordings were played as they worked, according to Swedish researchers from Stockholm and Lund universities.

Higher achieving children, on the other hand, performed better in silence. Goran Soderlund, a doctoral student in Stockholm, believes that differing brain dopamine levels explain the discrepancy.

Children with lower dopamine levels have lower brain activity. "They may perform better with noise because their brains are stimulated into higher activity, Soderlund said.”
