A noise gap has developed in American public life, and it’s a problem. The bars—at least those frequented by people under 40, who historically drive bottom-up political movements—have gotten louder. How loud? In 2012, the New York Times found that bars in that city regularly reached decibel levels so dangerously high that they violated federal workplace safety standards. The cafés, meanwhile, have gotten quieter. For centuries, coffee was used as a conversation stimulant. But in the present-day U.S., it functions primarily as productivity booster. Coffee long ago penetrated the workplace, and now cafés themselves have become workplaces. This really bugs me, both places are now terrible for meeting others.
