And it doesn’t have to be a deafening noise. The effects on the Body Mass Index of adults would be felt from 45 decibels, a level just above that of the cozy environment of a library (40 dB) and a little less than the noise of a conversation at home (50dB). This would correspond to accommodation located 35 km from a major airport in the United States. And the highest BMIs were detected among residents near airports exposed to sound levels of 55 dB or more, according to this research, carried out over a long period of 15 years, among 75,000 people living around the 90 main American airports.
