Functional magnetic resonance imaging (fMRI) studies involve substantial acoustic noise. This review covers the difficulties posed by such noise for auditory neuroscience, as well as a number of possible solutions that have emerged. Acoustic noise can affect the processing of auditory stimuli by making them inaudible or unintelligible, and can result in reduced sensitivity to auditory activatio...

This paper presents a new control structure to reduce torque ripple in switched reluctance motor. Although SRM possesses many advantages in motor structure, it suers from large torque ripple that causes some problems such as vibration and acoustic noise. In this paper another control loop is added and torque ripple is de ned as an objective function. By using fuzzy sliding mode strategy, the DC...

Noise compensation techniques for robust automatic speech recognition (ASR) attempt to improve system performance in the presence of acoustic interference. In feature-based noise compensation, which includes speech enhancement approaches, the acoustic features that are sent to the recognizer are first processed to remove the effects of noise (see Chapter 9). Model compensation approaches, in co...

In this paper, we use LMS filter and design a model with the help of Simulink using MATLAB 11a software. The effect of interference of acoustic noise in speech signals is the most common problem in speech processing. Acoustic noise reduces the intelligibility of speech signals by masking them. We need to suppress this acoustic noise for better communication. By using this technique, the acousti...

The spontaneously hypertensive (SH) rat model of ADHD displays impaired motor learning. We used this characteristic to study if the recently described acoustic noise benefit in learning in children with ADHD is also observed in the SH rat model. SH rats and a Wistar control strain were trained in skilled reach and rotarod running under either ambient noise or in 75 dBA white noise. In other ani...

Extracting the coherent component of the ambient noise field propagating between a pair of passive receivers provides a means for passive acoustic sensing of the ocean environment. For instance, the arrival-times structure of the ambient noise cross-correlation time-function between a pair of receivers can yield an estimate of the arrival structure (or wavefronts) of the actual time-domain Gree...
