A few years ago, the American Public Health Association declared noise to be a public health hazard, which leads to more heart disease, hearing loss and other health impacts as well as lost productivity. Noise isn’t just about decibel level – although that’s important - it is about its constancy and intrusiveness. Who likesthat high-pitched car alarm that goes off at 3 am or the cacophony of bleeping machines that overload your nervous system, when you are trying to heal in a hospital bed?

Chris Berdik, a science and education journalist, first became interested in noise when he wrote a feature for the Boston Globe on noise pollution. He was captivated by the idea that a pollutant could inflict such wide-ranging harms to mental and physical wellbeing, which were both pervasive and inscrutable. Some people regarded noise as lethal as secondhand smoke, while others saw noise complaints as a proxy for being anti-tech or disliking your neighbors.

Berdik’s research took him to European villages and cities where EU regulations require settlements of a certain size to identify noise-protected “quiet areas”. He concluded that in order to mitigate the harmful effects of noise, loudness needs to be controlled and quiet protected. How often do we find ourselves having to shout in restaurants or repeat our orders; why can’t we focus on a deadline at work instead of our concentration being hijacked by the chatter of coworkers? Berdiksuggests that “soundscapes” in workplaces, schools, hospitals and restaurants need to be planned in advance, so they can support not undermine our larger endeavors.
