For Your Ears Only

Advertisers are using a new cutting edge tool to try to make sure you don't tune out their messages: They're sending them directly to your ears...and your ears alone.

The technology transmits sound in a narrow beam, almost like a beam of light, directly to someone's ears. For instance, Court TV has put the technology is some bookstores to market its upcoming crime series.

The so called Audio Spotlight was created by the Watertown company, Holosonic Incorporated. WBUR's Deborah Becker recently sat down with company CEO Joe Pompei and asked him to explain how the device works.
