A sound idea

Re: “Hos­pi­tals are awash in noise,” Mod­ern­Health­care.com, April 25: One tech­nol­ogy that is miss­ing from hos­pi­tals is white noise damp­en­ing.

In use for over 40 years in such noisy places as of­fice bullpens, air­ports and busy re­tail out­lets, this tech­nol­ogy uses sound to can­cel out other sound. If you want to see—or hear—what it is like, check out the Amer­i­can Air­lines con­course at O’Hare In­ter­na­tional Air­port in Chicago.

One of the world’s busiest con­courses is now al­most as quiet as a li­brary.
