Hazardous Exposure to Impulse Noise

The Journal of the Acoustical Society of America, 1968
This paper presents impulse-noise damage-risk criteria based on conclusions of independent British and American studies and on the work of other research workers in this field. Most of the studies that led to this criterion were performed with noise from small arms, but the criterion is general enough to permit assessment of most other types of impulse

Robust Adaptation in Impulsive Noise

IEEE Transactions on Signal Processing, 2016
The popular least-mean-squares (LMS) algorithm for adaptive filtering is nonrobust against impulsive noise in the measurements. The presence of this type of noise degrades the transient and steady-state performance of the algorithm. Since the distribution of the impulsive noise is generally unknown, a robust semi-parametric approach to adaptive ...

Speech recognition in impulsive noise

1995 International Conference on Acoustics, Speech, and Signal Processing, 2002
This paper presents experimental results on the use of noise compensation schemes with hidden Markov model (HMM) speech recognition systems operating in the presence of impulsive noise. A measure of signal to impulsive noise ratio is introduced, and the effects of varying the percentage of impulsive noise contamination, and the power of impulsive noise,

Adaptive Blind Equalization in Impulsive Noise

2020 54th Asilomar Conference on Signals, Systems, and Computers, 2020
This work investigates the problem of blind channel equalization in the presence of burst noise. Modeling impulsive noise distribution as generalized-Gaussian, we derive an appropriate criterion for blind equalization. Our method exploits Wijsman’s theorem and develops a maximal-invariant test of equally-likely pulsed signals against impulsive ...

Adaptive impulse noise filtering

IEEE International Conference on Acoustics Speech and Signal Processing, 1993
The authors present a preprocessor to mitigate the effects of the impulse noise. In contrast with previous work, the proposed preprocessor requires no information about the correlated background process and can adapt as the background process changes. An adaptive nonlinear filter (preprocessor) introduced mitigates the effects of the impulses when the ...

Impulse noise: Critical review

The Journal of the Acoustical Society of America, 1986
A review of the last 10 years of research on impulse noise reveals certain insights and perspectives on the biological and audiological effects of exposures to impulse noise. First, impulse noise may damage the cochlea by direct mechanical processes. Second, after exposure to impulse noise, hearing may recover in an erratic, nonmonotonic pattern. Third,

Impulse noise cancellation in multicarrier transmission

2001 IEEE International Conference on Acoustics, Speech, and Signal Processing. Proceedings (Cat. No.01CH37221), 2002
A parallel between Reed Solomon codes in the complex field and multicarrier transmission using OFDM is first presented. This shows that when the signal is sent over some channel composed of Gaussian plus impulse noise, the impulse noise can be removed by a procedure similar to channel decoding, using information carried by the "syndrome". These results

Understanding Impulse-Noise Measurements

IEEE Transactions on Communications, 1972
Numerous articles have been written on the general properties of impulse noise, models for it, and its effects on data transmission. Most of these make an attempt to apply or generate some particular theory with respect to the phenomenon. A literature search has given rise to an awareness of the need for a paper devoted solely to the idiosyncrasies of ...

I. Impulse Noise of Different Durations

Acta Oto-Laryngologica, 1987
This paper describes a comparison between auditory threshold elevations and morphological cochlear changes evaluated with scanning electron microscopy in order to identify cochlear defects in guinea pigs exposed to impulse noise of varying durations. There was a significant difference in the auditory threshold shifts between animals exposed for 3 and ...
