Modeling otoacoustic emission and hearing threshold fine structures.
TLDR
A class of cochlear models which account for much of the characteristic variation with frequency of human otoacoustic emissions and hearing threshold microstructure is presented and successfully describes in particular the characteristic quasiperiodic frequency variations (fine structures) of the hearing threshold. Expand
Measuring distortion product otoacoustic emissions using continuously sweeping primaries.
TLDR
DPOAE obtained with sweeping tones can be used either to get more rapid estimates of DPOAE fine structure or to obtain estimates from the generator region uncontaminated by energy from the reflection region. Expand
Experimental confirmation of the two-source interference model for the fine structure of distortion product otoacoustic emissions.
High-resolution measurements of distortion product otoacoustic emissions (DPOAEs) from three different experimental paradigms are shown to be in agreement with the implications of a realisticExpand
New off-line method for detecting spontaneous otoacoustic emissions in human subjects
TLDR
The digitization of five minute samples of ear canal signals, combined with sophisticated data analysis, produced a substantial reduction in the emission detection threshold and the relationship between emission power, frequency, and full width at half maximum appears to be in agreement with the implications of a noise perturbed Van der Pol oscillator model of spontaneous emissions. Expand
The effect of stimulus-frequency ratio on distortion product otoacoustic emission components.
TLDR
The factors shaping DPOAE-component behavior are discussed and some cursory implications for the choice of stimulus parameters to be used in clinical protocols are discussed. Expand
Modeling the combined effects of basilar membrane nonlinearity and roughness on stimulus frequency otoacoustic emission fine structure.
TLDR
It is shown that nonlinearity can unexpectedly, in some cases, significantly modify the level and phase behaviors of the otoacoustic emission fine structure, and actually enhance the pattern of fine structures observed. Expand
Impaired cochlear function correlates with the presence of tinnitus and its estimated spectral profile
The presence of tinnitus often coincides with hearing loss. It has been argued that reduced peripheral input leads to frequency-specific increase in neuronal gains resulting in tinnitus-relatedExpand
A comparative study of avian auditory brainstem responses: correlations with phylogeny and vocal complexity, and seasonal effects
TLDR
A comparative study of the peripheral auditory system in six avian species indicates that auditory brainstem responses measures in the spring broadly correlated with both vocal complexity and, in some cases, phylogeny, however, these auditory brain stem response patterns shift from spring to winter due to species-specific seasonal changes.

  • 1 November 1988
TLDR
Ear-canal measurements of the interactions of external tones with spontaneous emissions indicate that, although beating is often detected near threshold maxima, stimuli close to threshold minima are perceived as tonal because the emission is frequency locked by the external tone. Expand
Modification of spontaneous and evoked otoacoustic emissions and associated psychoacoustic microstructure by aspirin consumption.

TLDR
Monitoring of spontaneous emissions, evoked emissions, and threshold microstructure in four subjects provided a technique for further exploring the relation between otoacoustic emissions (spontaneous and evoked) and psychoacoustic thresholdmicrostructure. Expand
