A Cell Phone Headset That Blocks Out Noise

Techstination feature for Wednesday, September 15, 2004

A cell phone headset…that blocks out noise. Bloomberg Boot Camp, a report on today's technology. There are lots of pretty good headsets on the market…that are fine to use when you aren't surrounded by noise. Not many are very useful…in a noisy airport… or train station for instance. But a new headset called the Aliph Jawbone…can turn this…(sound) into this…. (sound) CEO Patrick McVeigh says the Jawbone uses multiple microphones and sensors…

"We actually have three sensors as it were. There are two microphones, a voice microphone and a noise microphone. And then we have what we call a voice activity sensor which touches the cheek simply to tell the system whether or not you're speaking. Based on that information and the information from the two microphones, five hundred times a second, we adapt our signal processing to extract the noise and enhance the inbound audio for the user."

. The company has been working with the Department of Defense to enable communications in environments that are hostile in more ways than one. It will begin selling the Jawbone to consumers this fall. The downside is the price…about 150 dollars. That's more than what most people pay for their cell phones. It will be available first for Nokia, Motorola and Sony Ericsson models…

"Two or three other phones would pick up another 30 to 40 percent of the market and we are working on those."
