theCOBRA Noise Canceling Microphone
Rated among the best noise canceling microphones, theCobra cartridge can be
added to any Cobalt “blue” headset. For the ultimate headset, add theCobra to
our ANR active noise cancellation optioned headsets.
Dramatic Noise Reduction
TheCobra has an average 10 dB improvement over standard headset mics
with a maximum of 30 db improvement in average speech bandwidth.
The Best Speech Intelligibility
theCobra microphone enables crystal clear speech in 100+ dB noise.
Improves intelligibility scores to 82% in noise levels of 105 dB
compared to 72% intelligibility for standard microphone.
Ideal for high noise environments, theCobra’s
noise rejection performance surpasses all
other microphone technologies, and is
particularly stark in high noise levels.
Noise Rejection takes a new shape
Patented noise cancellation technology rejects
extraneous background noise. An acoustically
based approach; theCobra accentuates the
speaker’s voice by concentrating it on the front port
of a two-port microphone, while deflecting background noise
from the back port.
Passive Noise Canceling Technology
No processor is required, so power requirements are low.
Active noise canceling technology relies on creating an anti-noise signal to cancel out
the noise in a signal. Since there is inherent overlap in frequencies between speech and
noise, this results in speech signals often being identified as noise and vice versa. An
observable consequence of this is distorted or garbled speech, and unsatisfactory noise
cancellation. It also requires a power supply (typically, additional battery). Other
electronic noise-canceling techniques use algorithms to identify a noise from a digital
signal and to filter it out using digital filters. These techniques are also frequency
dependent, which results in the same problems mentioned above.
Available in preamped or non-preamped electret, or dynamic versions.
Using our acoustically
based approach, theCobra
accentuates the user’s voice
by concentrating it in the
front of the microphone while
deflecting the voice from
the back port. The background
noise is directed towards both
ports to reduce noise vibration.
