In this paper, the powerline noise reduction with different data lengths were compared by numerical simulation; the results show that there is always an optimal data length, not a single cycle but several cycles that can achieve maximum powerline noise suppression.
In order to obtain fast but smooth convergence with maximum possible echo and noise suppression, a set of updating constraints is proposed based on various speech characteristics (e.g., energy and correlation) of reference and current frames considering whether they are voiced, unvoiced, or pause.
It utilizes several noise-suppression techniques for maximum noise reduction and describes the advantages as well as disadvantages of several other techniques currently in use at industry.
With the maximum noise overestimation factor γ WF1 and the fixed overestimation γ WF2, the filter coefficients for the residual cross-talk suppression postfilter characteristic result in G m RCS ( ℓ, k ) = 1 - min γ WF 1, γ WF 2 G m ENR ( ℓ - 1, k ) · Φ ̂ N ~ N ~, m ′ ( ℓ, k ) Φ ̂ Y ~ Y ~, m ( ℓ, k ), (19).
The noise suppression feature works in this mode as well.
"We are also exploring new techniques for low noise jet exhaust, integrated fan noise suppression, airframe noise suppression and computer customized airport noise abatement".
Spence reckons this is because umami may be immune to noise suppression.
The Dragon has noise suppression for better talking and listening in noisy places.
Noise suppression can also play an important role in making cellphone networks more efficient, he said.
When the noise suppression chip is turned on, there is a striking decline in background noise while the speaker's voice remains clearly audible.
