Trailing-edge noise reduction of a wing by a surface modification [PDF]
, 2021 There is an increased emphasis on reducing airframe noise in the last decades. Airframe noise is sound generated by the interaction of a turbulent flow with the aircraft geometry, and significantly contributes to the overall noise production during the ...

Noise reduction method based on generalized subtractive beamformer [PDF]
, 2006 Combating noise signals is still a very important and challenging research topic. Previously, we presented a subtractive-beam former-based noise reduction algorithm using paired microphones, which was shown to be effective in reducing directional noise ...

Proceedings of the IEEE, 2002 Different methods for removing noise contaminating time series are presented, which all exploit the underlying (deterministic) dynamics. All approaches are embedded in a probabilistic framework for stochastic systems and signals, where the two main tasks, state and orbit estimation, are distinguished. Estimation of the true current state (without noise)

Noise of CCD reduction based on three-D noise model [PDF]
, 2012 This paper proposed proper noise reduction methods for the two different noises (i.e. temporal noise and special noise) based on the 3-D noise model of scientific-grade CCD. Noise reduction calculations have been made with these methods.
