AIM: To review the literature about the effects of environmental noise on the hearing ability of firefighters. METHOD: The PubMed and Scielo databases were searched and studies from 2002 to 2012 that included the keywords ...

In this paper, the low-frequency (LF) noise in standard n-channel triple-gate Bulk FinFETs has been experimentally investigated with variation in the fin widths (W<inf>Fin</inf>), channel lengths (L) and gate dielectric. ...

Speech processing systems are very important in different applications involving speech and voice quality such as automatic speech recognition, forensic phonetics and speech enhancement, among others. In most of them, the ...

Noisy data are common in real-world problems and may have several causes, like in accuracies, distortions or contamination during data collection, storage and/or transmission. The presence of noise in data can affect the ...

This study proposes a criterion for evaluating the turbulent boundary layer displacement thickness when predicting airfoil trailing-edge noise with semi-empirical methods. The boundary layer integral parameter is usually ...

We frequently employ the intuitive concept that a multiplicative noise can expel a system towards the field values for which intensity is negligible. This process applies even when such noise effects are opposed to the ...

In the presence of correlated and/or heteroscedastic noise, i.e., for measurement noise which is not independent and identically distributed (iid), new expressions are required to estimate multi-way calibration figures of ...
