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.

In this paper, we added some Gaussian noise in the autoencoder process to improve the robustness of the neural network (Figure 10) and to enhance the antinoise ability of the model.
Furthermore, to evaluate the antinoise ability of the above three algorithms, the reconstructions with Gaussian noise N([mu], [[sigma].sup.2]) are also considered, where [mu] represents the mean value and [[sigma].sup.2] represents the variance value of Gaussian noise.

The robustness of the proposed method can be proofed by estimating the antinoise performance of damage identification method.
Apparently, the proposed algorithm based on extended Kalman filter and the algorithm based on adaptive Fourier filter achieved better performance in antinoise ability.
The rise comes despite the introduction of antinoise legislation in 2004.
In our workplace we would like to make antinoise panels based on crushed plastic boards of PCBs sticked by special adhesive mixture.
It uses a microphone inside the ear cup to monitor incoming noises, then uses electronics to send an "antinoise wave" that's directly opposite to the one coming in to negate the sound.
The resultant "antinoise" signal is presented through an earphone at equal amplitude to, but 180 degrees out of phase with, the original noise, causing energy cancellation.
The protesters were supporters of the antinoise campaign group HACAN ClearSkies, which is mainly made up of locals opposed to further expansion of Heathrow.
The judges were considering an appeal by the UK Government to an earlier Strasbourg court victory on night flying for eight members of the Heathrow antinoise group,HACAN ClearSkies.
