The improved algorithm reduces the impact of background noise fluctuation.
The frequency-independent background noise is due to thermal and shot noise mechanisms.
Perhaps, this is due to the background noise and primary noise differences that create a powerful anti noise for canceling the original noise.
This might supply a new insight into how MIC could be mitigated.

The proposed method is robust to background noise and reverberation.
This paper proposes a background noise classifier based on a new, computationally simple, robust set of acoustic features.
The result shows that annoyance responses in low background noise regions are much higher than those in high background noise regions, even though aircraft noise levels are the same.
