Smart Panel Technology for Broadband Noise Reduction

Noise & Vibration Worldwide, 2003
The possibility of a broadband noise reduction by piezoelectric smart panels is demonstrated. A smart panel is basically a plate structure on which piezoelectric patches with electrical shunt circuits are mounted and sound absorbing material is bonded on the surface of the structure. Sound absorbing material can absorb the sound transmitted at the mid

Reduction of broadband noise in speech by spectral weighting

ICASSP '80. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
This paper describes a general approach for reducing the level of broadband noise in speech. The method is derived by considering the probability density functions of the complex spectrum parameters corrupted by additive noise. This leads to a general formulatian of the problem and a class of speech spectral estimators is introduced, which include ...

On the Noise Optimum of FET Broadband Transimpedance Amplifiers

IEEE Transactions on Circuits and Systems I: Regular Papers, 2012
The optimum sizing of the front-end FET in transimpedance amplifiers (TIA) is revisited. Analytical solutions based on a second-order shunt-feedback TIA model that includes the feedback-resistor noise are derived. It is shown that the optimum FET size can be smaller or larger than suggested by the well-known capacitive matching rule, depending on ...
