The new echo cancellers
have been designed to eliminate the echoes that occur during phone calls.
Meanwhile, collected results may be assessed and perhaps managed to generate a generic echo-canceller that can work with various noise and echo levels in order to create a database that may lead to development of novel environmental friendly echo-noise canceller
With regard to the transmission path of acoustic echo and noise along the drillstring, a joint acoustic echo and noise suppression scheme using an acoustic echo canceller
and an acoustic insulation structure is provided for attenuating the unwanted multiple disturbances before they can interfere with the required upward travelling waves at the receiver.

In the proposed method, the ESSNR estimated by the hybrid domain SNR estimation method is inputted to the adaptive noise canceller
, and the [mu] calculated from the ESSNR and equation (4) is used as a factor in the adaptive noise canceller
"Equipped with a number of features such as vocal effects, karaoke star, voice canceller
, key changer and a variety of DJ specific controls, the OK99 simply engages people in any party and at any venue to help create the most memorable musical moments."
The investigators have now performed experiments and mathematical modeling on the eye development of the fruit fly, showing that the JAK/STAT signaling pathway functions as a biological-noise canceller
Karaoke fans can eliminate the vocal track from almost any song adjust the pitch with Voice Canceller
and Key Changer while the Grab & Move handle and casters of the LG OK99 takes the definition of "portable audio system" to a whole new level, according to the company.
Based on a single-notch filter, a main-lobe canceller
of space spread clutter  is developed.
The other BSS outputs are then used for further noise cancellation in the form of references for an adaptive noise canceller
