Slight correction:

“While the first microphone captures your voice, the second captures your voice along with background noise, compares the two, and …”

The real idea is that the lower mic captures your voice and the background noise, and the auxiliary mic captures mostly just the background noise. It can then use the auxiliary mic’s signal and “subtract” that sound from the sound that the main mic picked up, leaving you with only the sound of your voice being transmitted.

It’s similar to another technique that aims to remove or lessen the vocals on a music track, because most recordings will have the instruments in only one or two channels of the audio (especially rear channels), but the vocals are usually on at least 3 channels (front L/R and center), sometimes more. So by canceling out the audio that is common to all 3 channels, you can usually reduce the sound of the vocals, leaving only the music, which can be useful for things like karaoke machines.

Cool to see, believe it or not, the Grateful Dead pioneered this idea and technology, to eliminate background noise, echo and feedback. They perfected this in the early 70′s, some of the sound people went on to work for sennheiser later on. This was the early start to noise cancelling tech.

I love my Nexus One and this is just another one of the reasons why I do, the Noise Cancellation IS excellent! Try it for yourself if you don’t believe it.

The Motorola Droid has it too. I guess HTC adding it is news because the sound quality of some of its WM phones is poor any improvement to the hardware is welcome.

this feature in fact WORKS excellent. (Nexus One)
a few days ago, I was with a friend in a crowded applebees (game night), he has an iPhone, and he didn’t believe me on this, so he called his fiance from my phone telling her he was still in his office, and she believed him (he was just tricking her), he asked her “dont u hear all the people in here screaming?”, she didn’t hear anything, the he called her again from his iPhone and she heard everything and he was amazed.

To be honest, I didn’t think it was going to work as well bc the place was CROWDED and LOUD, but it, in fact works.

And hate to break it to the 20,000 Nexus owners, but as far as Android phones go, the Droid had this first. It’s situated right in the center top of the back side of the phone. Nothing to see here…move along…move along.

blackberry has been doing this for years, good to see someone else pick up on it

I would also like to see someone copy the blackberry feature where when you holster your phone and it locks the keys and puts the phone in sleep mode
