“These exposures to noise and other things” are stressful, and chronic stress can lead to “a cascade of pathophysiological changes,” including inflammation, and changes in appetite or a person’s insulin sensitivity. "In a 2022 study in the journal Environmental Research, Vincens found a link between railway noise and incidences of diabetes, even when accounting for variables such as sociodemographic and lifestyle factors," Bittel reports.
Luca Fredianelli, an acoustic technician with the Italian National Council of Research, told Bittel, "If the sounds are quite stable, in the end, we do not perceive it at all." Bittel elaborates: "It’s the less intense but more unpredictable noises, such as squeals, whistles, and grinding brakes, that really bother people, since they’re difficult to acclimate to, he said."
