Pittsburgh Steel Workers Accidentally Invented a Focus Trick That Sound Scientists Are Now Obsessed With
In the bone-rattling noise of early 20th-century Pittsburgh steel mills, veteran workers developed an odd habit: humming at a low, steady pitch to stay focused during 12-hour shifts. Nobody thought much of it at the time. But auditory neuroscientists studying what they're calling 'acoustic anchoring' are discovering that those workers had stumbled onto something genuinely powerful — and surprisingly easy to try yourself.
