I desperately wish more people would realize how sensitive we all are to noise. It’s hard to imagine that anyone who thought about the impact of noise on themselves and others would choose to use a leaf-blower, for example.

Experts say your body does not adapt to noise. Large-scale studies show that if the din keeps up—over days, months, years—noise exposure increases your risk of high blood pressure, coronary heart disease, and heart attacks, as well as strokes, diabetes, dementia, and depression. Children suffer not only physically—18 months after a new airport opened in Munich, the blood pressure and stress-hormone levels of neighboring children soared—but also behaviorally and cognitively. A landmark study published in 1975 found that the reading scores of sixth graders whose classroom faced a clattering subway track lagged nearly a year behind those of students in quieter classrooms—a difference that disappeared once soundproofing materials were installed. Noise might also make us mean: A 1969 study suggested that test subjects exposed to noise, even the gentle fuzz of white noise, become more aggressive and more eager to zap fellow subjects with electric shocks.

Even when not intentionally deployed for harm, the sound of drilling, barking, building, crying, singing, clomping, dancing, piano practicing, lawn mowing, and generator running becomes, to those exposed, a source of severe anguish that is entirely at odds with our cavalier attitude toward noise. “It feels like it’s eating at your body,” a man plagued by a rattling boiler told a reporter. A woman who was being accosted on all sides by incessant honking told me, “The noise had literally pushed me to a level of feeling suicidal.” For those grappling with it, noise is “chaos,” “torture,” “unbearable,” “nauseating,” “depressing and nerve-racking,” “absolute hell,” and “an ice pick to the brain.” “If you didn’t know they were talking about noise, you might think they were describing some sort of assault,” Erica Walker, an environmental-health researcher at Boston University, has said. This has spurred scientists, physicians, activists, public officials, and, albeit less in the United States, lawmakers to join in the quest for quiet, which is far more elusive than it may seem. “Quiet places,” says the acoustic ecologist Gordon Hempton, “have been on the road to extinction at a rate that far exceeds the extinction of species.”
