antinoise

[‚an·tē′nȯiz]
(acoustics)
Noise that is deliberately created to mimic an existing noise field in antiphase so that the two fields cancel each other, resulting in silence. Also known as antisound.

Additionally, compared with the segmentation results using FCM (Figures 8(e), 9(e), and 10(e)), the improved sFCM can produce segmented images that are smoother and have better antinoise capabilities because the latter takes into account the relevance of the neighborhood information and provides compensation in the noise region.
4] presented an algorithm that incorporated the neighboring spatial information of a pixel in local window into the objective function of the FCM algorithm to improve antinoise capability (called BCFCM).
The new technology will also allow automakers to make lighter vehicles as they will not need to add antinoise materials to chassis, they said.

The antinoise circuitry can squelch sound at frequencies below roughly 1,200 hertz, reducing the noise to as little as one-eighth of its untreated loudness, says Michael A.
The future may see increased application of these systems, particularly where one antinoise device can "cover" the noise from vibrators and other equipment at the same time.
An antinoise generator, a device designed to reduce the sound of buses, is being tested in New York, Houston and two transit systems in Southern California.
Engineers are now designing equipment that uses antinoise to silence loud machinery.
The Noise Cancellation Technologies exhaust muffler employs a feedback control design to generate an antinoise signal at the end of an automobile exhaust pipe.
The performance of BCS and LARS algorithms is satisfactory in the first two experiments, but their antinoise performance is no match to our scheme.
In this paper, we take the use of block dictionary learning LC-K-SVD algorithm to build up overcomplete dictionary and then use stOMP algorithm to carry on classification process, in order to accelerate the speed of traditional OMP algorithm, combined with antinoise factor.
Such a ruling could lead to challenges by antinoise groups at other UK airports.
