In the environment with stationary noise where the speech is not so bad and easier to understand, the [L.sub.2] regularization can improve the quality of the speech, making the speech more natural and clearer.
The latter can be interpreted as a stationary noise component.
Because the adaptive filter is not involved in the nature of the noise itself, it can be used both for stationary noise cancellation and quasi-stationary noise cancellation.
But this approach is suitable only for stationary noise conditions, for non-stationary condition this method does not perform well.
On the study of reducing the disturbance on driver's attention induced by low frequency vehicle interior stationary noise, a subjective evaluation is firstly carried out by means of rank rating method which introduces Distraction Level (DL) as evaluation index.
Furthermore, we found that the figure for CNEg was more similar to the stationary noise reference than CNEp was.
Assuming stationary noise, its correlation function has time translational invariance, and we find
Against stationary noise, the algorithm improved comprehension from an average of 35% to 85%.
They tested the algorithm's effectiveness against "stationary noise"-a constant noise like the hum of an air conditioner-and then with the babble of other voices in the background.
During the project, stationary noise monitoring equipment was installed and a special method for calculating noise contours was applied.
In this work, we limit the study to the stationary noise components, and we explicit the PSD of the noise at the receiver port, namely, [MATHEMATICAL EXPRESSION NOT REPRODUCIBLE IN ASCII] (f) as the sum of contributions due to four noise terms.
It modulates any stationary noise sources in the oscillator circuit (thermal noise of the resistor and shot noise of the transistor) and makes cyclostationary noise sources.
