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.

Prevalence of spontaneous otoacoustic emissions in adults revisited
Hearing Research, 1997The potential influence of spectral analysis factors on estimates of the prevalence of spontaneous otoacoustic emissions (SOAE) was explored. The detection of a SOAE was influenced by two spectral factors: (1) the frequency resolution of the spectrum, and (2) the number of spectral averages.

Spontaneous otoacoustic emissions in the nonhuman primate: A survey
Hearing Research, 1985A number of reports have described a relatively high incidence of spontaneous otoacoustic emissions (SOAEs) in recordings made from the sealed human ear canal. Our attempt to detect similar emissions in 122 presumably normal-hearing ears from 61 monkeys revealed SOAEs in 5% of the primates and 2.5% of the ears tested.

Amplitude and frequency fluctuations of spontaneous otoacoustic emissions
Journal of the Acoustical Society of America, 1990Amplitude and frequency fluctuations of spontaneous otoacoustic emissions have been studied. Spontaneous otoacoustic emissions were recorded from eight human ears and two frog ears (Rana esculenta). Record length typically was 80 s. For a recorded emission signal, the amplitude signal A(t) (average A0) and time intervals T(ti) between successive ...

Aspects of spontaneous otoacoustic emissions in healthy newborns
Hearing Research, 1993Spontaneous otoacoustic emissions (SOAEs) are pure-tone like signals, spontaneously present in the ear canal. In normal adult ears the prevalence of SOAEs is reported to be 30-70%, probably depending on the noise floor of the recordings. In infant studies, results on the SOAE prevalence are rare.

Spontaneous otoacoustic emissions in schoolchildren
International Journal of Pediatric Otorhinolaryngology, 2016Spontaneous otoacoustic emissions (SOAEs) are one of the least studied types of otoacoustic emissions (OAEs). The purpose of this study was twofold: first, to determine the prevalence of SOAEs in schoolchildren, and second to test whether there was dependence between the presence or absence of SOAEs in a subject and the corresponding level of their ...

Spontaneous otoacoustic emissions in a dog
Hearing Research, 1984Intense (up to 59 dB SPL) spontaneous otoacoustic emissions are produced by both ears of a young dog. The right ear produces a single, very narrow-band (less than 4 Hz) emission at about 9100 Hz. Brainstem evoked-response audiometry suggests that this emission is generated near the transition between normal and abnormal regions of the cochlea.

A Case of 'Spontaneous Otoacoustic Emission'
Archives of Otolaryngology - Head and Neck Surgery, 1987A 25-year-old man produced a continuous high-pitched pure tone (6.1 kHz, 37.2-dB sound pressure level) in his right ear. The tone was not audible to the patient. He had sensorineural deafness over 1 kHz with a dip of 45 dB at 6 kHz. The tone was considered to be emitted through the eardrum from the inner ear, ie, a "spontaneous otoacoustic emission".

The Contribution of Spontaneous Otoacoustic Emissions to the Click Evoked Otoacoustic Emissions
Ear and Hearing, 1995This investigation determines whether spontaneous otoacoustic emissions (SOAE) contribute to click evoked otoacoustic emissions (EOAE).Bilateral SOAEs and click EOAEs were recorded for 81 normal-hearing subjects by using an ILO88 Otodynamic Analyzer.Results suggest that several factors from COAEs contribute to the level and the shape of the click EOAE.

Spontaneous otoacoustic emissions in teiid lizards
Hearing Research, 2018SOAE from the last major lizard family not yet systematically investigated, the teiids, were collected from the genera Callopistes, Tupinambis and Cnemidophorus. Although their papillae show characteristics of the family Teiidae, the papillae differ both in their size and in the arrangement of uni- and bi-directional hair-cell areas.
