Scientists discover brain patterns affect response to noise
Some individuals are more susceptible to sounds as they are sleeping in bed than others, due to the patterns in their brain waves, according to new research.
Scientists at Harvard Medical School have published findings in the latest edition of Current Biology which show the importance of brain rhythms on sleep disruption.
Sleep spindles can help to block out the effect of noise and allow certain people to rest without interruption, researcher Jeffrey Ellenbogen explained.
He said: “The more sleep spindles your brain produces, the more likely you’ll stay asleep, even when confronted with noise.”
Volunteers were monitored over three nights in a test lab where they were exposed to a series of sounds at varying levels.
It is hoped that the results will go some way towards aiding the production of devices or techniques which will enhance better sleeping.
Elsewhere, a study into the effect heavy traffic sounds have on slumber found that a person’s alertness was reduced and their reaction times slowed following exposure to loud noise.
