Add a Cobra cartridge to any Cobalt blue muff headset and enhance voice clarity with one of the highest rated noise cancelling microphones. For the “ultimate headset experience”, add Cobra to our ANR active noise cancellation headsets.
Cobra microphones use patented noise cancellation technology to reject background noise and enhance speech. Special acoustic design concentrates the voice at the front port of the 2-port microphone and deflects background noise from the rear port.
Cobra offers a 10 dB average improvement over standard headset microphones, with a maximum of 30 dB improvement in average speech bandwidth.
Ideal for high noise environments, Cobra allows crystal clear speech in 100+ dB noise. It improves intelligibility scores up to 82% in noise levels of 105 dB compared to 72% intelligibility rating for standard microphones.
Cobra uses passive noise cancelling technology, which requires no processor or battery to operate.
What is Passive Noise Cancelling Technology?
Most microphones use active noise cancelling technology, creating an anti-noise signal to cancel out noise in a signal. Since frequencies organically overlap between speech and noise, speech signals often wrongly identify as noise. Noise can also identify as speech. The result is distorted speech and unsatisfactory noise cancellation. Active noise cancelation also requires an additional power supply like a battery.
Some electronic noise-canceling methods use algorithms to identify a noise from a digital signal, then filter out noise with digital signals. These methods are dependent on frequency and show similar overlap distortion problems.
Cobra microphones use passive noise canceling technology which does not require the use of an additional power source (battery) to operate. Passive noise canceling works through the unique physical design of the microphone which filters out unwanted ambient noises.
