Jawbone II Bluetooth NoiseAssassin - Gold
Product Description
Key Features
Detailed
Description:
Jawbone eliminates real world
noise better than any other headset because it is the only headset that
can accurately separate speech from ambient noise.
In today's mobile world, 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 |
