Noise control and utility: From regulatory network to spatial patterning [PDF]
, 2020 Stochasticity (or noise) at cellular and molecular levels has been observed extensively as a universal feature for living systems. However, how living systems deal with noise while performing desirable biological functions remains a major mystery ...

Blockwise Subspace Identification for Active Noise Control [PDF]
, 2000 In this paper, a subspace identification solution is provided for active noise control (ANC) problems. The solution is related to so-called block updating methods, where instead of updating the (feedforward) controller on a sample by sample base, it is ...

Resonant control of stochastic spatio-temporal dynamics in a tunnel diode by multiple time delayed feedback [PDF]
, 2008 We study the control of noise-induced spatio-temporal current density patterns in a semiconductor nanostructure (double barrier resonant tunnelling diode) by multiple time-delayed feedback.

Sound pressure-dependent acoustic absorption by perforated rigid-frame porous materials
Acta AcusticaPorous materials are one of the most common classes of sound absorbers for acoustic treatments. However, thin layers of these classical materials are not efficient at absorbing low-frequency sound waves, which is a practical shortcoming.

Dental drill noise reduction using a combination of active noise control, passive noise control and adaptive filtering [PDF]
, 2007 Dental drills produce a characteristic high frequency, narrow band noise that is uncomfortable for patients and is also known to be harmful to dentists under prolonged exposure. It is therefore desirable to protect the patient and dentist whilst allowing
