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
