![]() Yes!! You read that correctly, sustained exposure to background noise does harm your heart. To test this hypothesis, his group exposed rat pups to pulses of white noise throughout their infancy and found that the pups’ cortices were devastated. “How would such noise affect the developing brain?” Merzenich wondered. There is always a din.” he continues “White noise is everywhere now, coming from fans in our electronics, air conditioners, heaters, and car engines.” “Infants are reared in continuously more noisy environments. Scientists believe that background noise might hamper the proper growth and development of infant’s brains.Īccording to Michael Merzenich, Professor Emeritus and Neuroscientist at the University of California, San Francisco. He also cited a similar study, conducted on children living in public high-rise housing above the Dan Ryan Expressway in Chicago, that study also found that the closer these children’s floors were to the highway, the lower their intelligence. Norman Doidge, a psychiatrist, researcher and faculty at the University of Toronto’s Department of Psychiatry, in his book The Brain That Changes Itself cites one disturbing study which showed that the closer children lived to the noisy airport in Frankfurt, Germany, the lower their intelligence was. It turns out, the continuous background noise also known as white noise which comes from machines and other appliances, can harm your brain, it does so by overstimulating your auditory cortex– the part of the brain that helps us perceive sound.ĭr. Generally speaking, sounds above 85dB are harmfulĪnd remember, the louder the noise and the longer the duration of exposure to it the more harm it causes. Leaves rustling is about 30 dB, a heavy traffic or lawn mower is about 90 dB, and a loud rock concert is about 120 dB. A sound’s loudness is measured in decibels (dB). Of course, background noises aren’t equal, some are louder and more harmful than others.
