A healthy soundscape, James says, “is not a wishy-washy amenity. It’s a potential public health factor we need to understand to make sure everyone has the same opportunities.” Smyth offers this advice: “We should think about soundscapes as medicine,” he told me. “It’s like a pill. You can prescribe sounds or a walk in the park in much the way we prescribe exercise. Do it 20 minutes a day as a lifetime approach—or you can do it as an acute stress intervention. When you’re stressed, go to a quiet place.” I’m ready.
