Modeling signal-to-noise ratio of otoacoustic emissions in workers exposed to different industrial noise levels

open access: yesNoise and Health, 2016
Introduction: Noise is considered as the most common cause of harmful physical effects in the workplace. A sound that is generated from within the inner ear is known as an otoacoustic emission (OAE).

Signal to Noise Ratio of a Coded Slit Hyperspectral Sensor

open access: yesSignals, 2022
In recent years, a wide range of hyperspectral imaging systems using coded apertures have been proposed. Many implement compressive sensing to achieve faster acquisition of a hyperspectral data cube, but it is also potentially beneficial to use coded ...

Remote Sensing Low Signal-to-Noise-Ratio Target Detection Enhancement

open access: yesSensors, 2023
In real-time remote sensing application, frames of data are continuously flowing into the processing system. The capability of detecting objects of interest and tracking them as they move is crucial to many critical surveillance and monitoring missions ...

Signal to Noise Ratio Loss Function

open access: yesCoRR, 2021
This work proposes a new loss function targeting classification problems, utilizing a source of information overlooked by cross entropy loss. First, we derive a series of the tightest upper and lower bounds for the probability of a random variable in a given interval.

Artifact reduction in multichannel pervasive EEG using hybrid WPT-ICA and WPT-EMD signal decomposition techniques [PDF]

open access: yes, 2014
In order to reduce the muscle artifacts in multi-channel pervasive Electroencephalogram (EEG) signals, we here propose and compare two hybrid algorithms by combining the concept of wavelet packet transform (WPT), empirical mode decomposition (EMD) and ...

Phrases in noise test (PINT) Brazil: effectiveness of the test in children with hearing loss

open access: yesBrazilian Journal of Otorhinolaryngology, 2021
Introduction: One of the main implications of hearing impairment is the difficulty in perceiving speech sounds, especially in noisy environments. Thus, the frequency-modulated system is considered an important educational tool for children with hearing ...

Signal-to-noise ratio and signal-to-noise efficiency in SMASH imaging [PDF]

open access: yesMagnetic Resonance in Medicine, 1999
A general theory of signal-to-noise ratio (SNR) in simultaneous acquisition of spatial harmonics (SMASH) imaging is presented, and the predictions of the theory are verified in imaging experiments and in numerical simulations. In a SMASH image, multiple lines of k-space are generated simultaneously through combinations of magnetic resonance signals in ...

Adaptive processing with signal contaminated training samples [PDF]

open access: yes, 2013
We consider the adaptive beamforming or adaptive detection problem in the case of signal contaminated training samples, i.e., when the latter may contain a signal-like component.
