The article “Everyday Noises Are Making Our Brains Noisier” from Nautilus explores how constant exposure to ambient sounds, even at “safe” levels below 60-70 dB, disrupts brain function by increasing neural noise and impairing sound processing, with studies showing that children from noisier, lower-income environments exhibit higher background brain activity and less precise auditory processing. At the same time, animal experiments reveal that such noise can reorganize the auditory cortex in young and adult subjects, suggesting that pervasive noise, including from devices like noise generators, may have lasting detrimental effects on our ability to interpret sound meaningfully.
