How Restaurants Got So Loud
28th November 2018
The coffee shop is quiet, probably as quiet as it can be while still being occupied. Even at its slowest and most hushed, the average background noise level hovered around 73 decibels (as measured with my calibrated meter).
That’s not dangerous—noise levels become harmful to human hearing above 85 decibels—but it is certainly not quiet. Other sounds that reach 70 decibels include freeway noise, an alarm clock, and a sewing machine. But it’s still quiet for a restaurant. Others I visited in Baltimore and New York City while researching this story were even louder: 80 decibels in a dimly lit wine bar at dinnertime; 86 decibels at a high-end food court during brunch; 90 decibels at a brewpub in a rehabbed fire station during Friday happy hour.
