A Bluetooth Headset That Cuts Out the Noise

Boot Camp feature for Thursday, March 29, 2007

A Bluetooth headset…that cuts through the noise. Bloomberg Boot Camp, a report on today's technology. It is far from the smallest and lightest Bluetooth headset on the market….but Aliph none the less…has paid a lot of attention to design with its latest model of the Jawbone. But design is only part of the story, the Jawbone uses Defense Department approved noise shield technology. What that means is that even in some of the noisiest environments….what you're saying on your mobile phone…will be heard. How does it work? Aliph CEO and founder Hosain Rahman….

"We have a little sensor that sits on your cheek and picks up the vibrations when you speak. We have two microphones that are built into this little feature here in the headset that are scanning your background environment 800 times a second. And so what that does is…it tells us exactly when you're speaking and we know exactly what the noise is. When you know those two pieces of information you can improve any audio application in mobile environments. So the first thing we do is we take out, subtract all the background noise from the cell phone call. We also adjust the incoming volume based on what we know of your environmental surroundings. Based on what we know about the background noise, we can adjust it up or down automatically to accommodate for the different types of noises."

The technology works….but it also puts the price of the Jawbone at the high end for non-stereo Bluetooth headsets. It is sold exclusively by Cingular…now AT&T for about 120 dollars. The performance and design have made it a bit tough to find. Bloomberg Boot Camp, I'm Fred Fishkin.
