Aliph Jawbone 2 Bluetooth Headset - "NoiseAssassin"
Jawbone eliminates real
world noise better than any other headset because it is the only
headset that can accurately separate speech from ambient noise.
The "NoiseAssassin"
The mobile
phone is the prevailing communication tool for business and personal
productivity, and people expect to be able to use their phones in all
environments without sacrificing audio quality. Jawbone's patented
NoiseAssassin™ technology is unique in its ability to separate speech
from ambient noise with remarkable precision. Jawbone's NoiseAssassin
is able to achieve this while other headsets cannot due to:
Patented VAS:
Jawbone's Voice Activity Sensor (VAS) is able to detect very accurately
when the person is talking and capture the frequencies of his or her
speech even in the presence of noise.
Advanced DSP Algorithms:
The NoiseAssassin algorithms were developed over a number of years for the Defense Advanced Research Projects Agency (DARPA).
These required 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 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.
