NoiseGard
The
NoiseGard™ hybrid Active Noise Cancellation system is a combination of 2
noise-cancellation systems composed of a total of 4 microphones. Two micro-
phones with openings to the outside of the headphones work as a Feed-Forward
active noise cancellation system that reduces noise in the high-frequency band,
while the other two microphones inside the headphones work as a Feed-Back
active noise cancellation system that reduces noise in the low-frequency band.
The combination of these 2 microphone systems results in a broad reduction in
noise covering a wider band of frequencies.
