Unpleasant noise enters through your ears, but it is relayed to the stress detection centre in your brain, setting off a cascade of reactions in your body
Unpleasant noise enters your body through your ears, but it is relayed to the stress detection centre in your brain. This area, called the amygdala, sets off a cascade of reactions in your body. If the amygdala is chronically overactivated by noise, the reactions begin to produce harmful effects.
When researchers analysed the brain scans and health records of hundreds of people at Massachusetts General Hospital, they made a stunning discovery: those who lived in areas with high levels of transportation noise were more likely to have highly activated amygdalae, arterial inflammation and – within five years – major cardiac events.
Compared with a quiet room, a passing freight train peaks at about four times as many decibels. But the difference in how loud the train sounds to the ear is much more dramatic: the train sounds more than 500 times as noisy. According to the World Health Organisation, average road traffic noise above 53 dB or average aircraft noise exposure above about 45 dB are associated with adverse health effects.A study
