Active noise control, which performs well at low frequencies can be applied on staggered windows to improve the noise reduction in the low frequency range, but with increased cost and system complexity8,9,10. Passive reactive silencers, like Helmholtz resonators, plenum chambers and side branch ...
The solutions to the noise problems were evaluated on a standard Turbopower and the sound power level of the cleaner was reduced from 87.5 dB(A) to 80.4 db(A) at a cost of 93.6 pence per cleaner. The designers' lack of experience in noise reduction was identified as one of the factors...
to apply an efficient filter intended for the reduction of the Gaussian noise component26,27,28,29,30. The rationale behind such an approach is that the nature of the two noise degradation types is distinct and they are easier to manage when considered...
The Kuwahara filter is a nonlinear noise-reduction filter that preserves edges [17]. It uses a sliding window approach to access every pixel in the image. The center pixel of the 1 × 5 neighborhood is supplanted by the median gray estimation of the 1 × 5 masks. A geometric filter is ...

results and experiment test show that the near end crosstalk and far end crosstalk are decreased by about 25 dB and 20 dB,respectively.Compared with the traditional decouple capacitor method,the shorting line proposed in this paper has benefits of wide bandwidth,easy layout and low cost. ...
However, while joining rather separate tasks, such as NS and AEC, into a single model be- came very straightforward using DL, it is not yet understood at what cost this comes: How much larger does a joint NS+AEC model have to be to achieve on par NS performance to an NS-only model...
This paper focuses on enhancing noise reduction performance, particularly through the refinement of signal quality fed into ANC systems. We discuss the main wireless technique integrated into the ANC system, equipped with some innovative algorithms, in diverse environments. Instead of using microphone ...
Optical techniques for noise reduction in DH mainly involve the reduction of the light coherence, engineering the light sources in the recording stage, or recording multiple holograms of the same object (i.e., the looks), which are captured under various realizations of the noise process. One ...
Focussing the attention to one or few permutation patterns will bring several benefits, including the reduction of the computational cost, hence the possibility of analysing structures at longer temporal scales; and eventually the creation of a catalogue of “chaotic fingerprints”. On the other hand...
