Chirp evoked otoacoustic emissions
Hearing Research, 1994The principles of short frequency sweeps (chirps) and their application to evoke transiently evoked otoacoustic emissions (TEOAE) are developed in comparison to using standard click stimuli. In contrast to click stimuli, chirp signals have the advantage of stimulating a freely selectable frequency range.

Effects of spontaneous otoacoustic emissions on distortion product otoacoustic emission
Auris Nasus Larynx, 2001It has been reported that spontaneous otoacoustic emission (SOAE) can prolong the responses or increase the echo power of transiently evoked otoacoustic emission (TEOAE), yet the effects of SOAE on distortion product otoacoustic emission (DPOAE) have been studied less thoroughly.

Resonant modes of otoacoustic emissions
Physiological Measurement, 2007Transiently evoked otoacoustic emission (TEOAE) signals were decomposed into basic components by means of the matching pursuit algorithm. The components were characterized by frequency, latency, time span and energy. The resonant modes characteristic for each person/ear were identified.

Influence of spontaneous otoacoustic emissions on distortion product otoacoustic emission amplitudes
Hearing Research, 1999Although the influence of the levels and ratios of the primary stimulus on the amplitude of distortion product otoacoustic emissions (DPOAEs) has been studied intensely, the influence of the presence of spontaneous otoacoustic emissions (SOAEs) has been investigated less thoroughly.

High rate otoacoustic emissions
The Journal of the Acoustical Society of America, 1993One of the practical problems of testing young children using evoked otoacoustic emissions (EOAEs) is that there is a need for the child to be quiet for a period of a minute or so. To achieve this can mean test periods of 10 min or longer. A new application of maximum length sequences (MLSs) to EOAEs is described that enables the test to be performed ...

Electrical Recording of Otoacoustic Emission
ORL, 2009<i>Conclusion:</i> Otoacoustic emissions (OAEs) could be detectable as cochlear AC potentials. Spontaneous otoacoustic emissions (SOAEs) were detected either electrically or acoustically, while evoked otoacoustic emissions (EOAEs) could be detected electrically but not acoustically.

A 7-month-old female Poodle was evaluated for a sound continuously emanating from its left ear. The frequency and intensity of the tone was matched by use of a multifrequency audiometer. The frequency and intensity of the sound were 9,594 Hz and 45.5 decibels sound pressure level, respectively.

A review of otoacoustic emissions
The Journal of the Acoustical Society of America, 1991Otoacoustic emissions measured in the external ear canal describe responses that the cochlea generates in the form of acoustic energy. For the convenience of discussing their principal features, emitted responses can be classified into several categories according to the type of stimulation used to evoke them.

Otoacoustic emissions and quinine sulfate
The Journal of the Acoustical Society of America, 1994A moderate dose of quinine sulfate, administered to three young adult males, reduced or eliminated various forms of otoacoustic emission (OAE). The individual differences in response to the drug were substantial, but a number of generalizations did emerge. The time courses of onset and recovery were considerably more rapid than for the parallel effects

Clinical Applications of Otoacoustic Emissions
Journal of Speech, Language, and Hearing Research, 1991On the basis of recent advances in auditory physiology, new tests of cochlear function have been developed using measures of otoacoustic emissions. In the present report, the clinical potential for each of the four basic emission types is examined. In addition, the practical advantages of examining the ear with two specific types of evoked emissions ...
