Electrocardiogram signal compression and de-compression system
TL;DR: In this paper, an electrocardiogram signal compression and de-compression system was proposed using the sign characteristics of the coefficients of the discrete cosine transform type IV and the characteristics of quantization of spectrum to perform the differential pulse code modulation of the spectrum for preserving the high frequency characteristics of spectrum.
Journal ArticleDOI
The application of frequency and time domain kurtosis to the assessment of hazardous noise exposures
TL;DR: When the audiometric and histological results are compared to a metric based upon kurtosis measured in the time and the frequency domain for each exposure, there is a clear indication that these statistical metrics are good predictors of the relative magnitude and frequency distribution of the acoustic trauma.

Method and apparatus for identifying sound in a composite sound signal
TL;DR: In this article, wavelet analysis and sorting of wavelet coefficient sets according to statistical parameters of each respective coefficient set is used to separate impulsive sound components in a composite sound signal.
Journal ArticleDOI
The cubic distortion product otoacoustic emissions from the normal and noise-damaged chinchilla cochlea
TL;DR: Auditory evoked potentials and cubic distortion product otoacoustic emissions indicated that the distortion product emissions were more sensitive, frequency-specific indices of noise-induced cochlear effects than pure-tone threshold measures.
Journal ArticleDOI
Audiometric and histological differences between the effects of continuous and impulsive noise exposures.
TL;DR: An experiment was designed to determine if, for equal SPL and power spectrum, the effects on hearing of high-kurtosis noise exposures and a Gaussian noise exposure are different and the extent to which any differences measured in terms of audiometric and histological variables are frequency specific.
