The Jawbone 2 is the next step in the integration of best-in-class noise elimination technology with personal design that is both humanistic and minimal. It has powerful noise suppression algorithms for use in the most extreme acoustic noise environments including battlefields and helicopters. The algorithms use Jawbone's two microphones and the VAS (Voice Activity Sensor) to accurately model the noise environment. Jawbone detects when and how a person is speaking, models the noise, and aggressively eliminates it. Conventional "noise eliminating" headsets do not have the VAS and can only estimate when speech is occurring with software-based Voice Activation Detection (VAD) systems. For these systems to work, the speech must be significantly louder or spectrally different from the noise. These systems fail in loud environments or in the presence of other people's speech. Furthermore, because they can't accurately identify the speech signals, they distort the speech in the process of attempting to eliminate the noise. The result of this distortion is a significant degradation in intelligibility and quality in order to achieve a perceptual reduction in noise.
