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.

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.

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.

Prevalence of spontaneous otoacoustic emissions in neonates
The Journal of the Acoustical Society of America, 1992The prevalence of spontaneous otoacoustic emissions (SOAEs) was measured in a group of 100 neonates and in a group of 50 normal-hearing young adults. The prevalence of SOAEs in the adult group (0.62) is at the high end of the range of prevalences reported in other surveys of adult SOAEs based on measurements using similar microphones. The prevalence of

Spontaneous otoacoustic emissions in the barn owl
Hearing Research, 1997Spontaneous otoacoustic emissions (SOAE) were studied in a bird, the barn owl. They were found in 79% of the ears investigated, and each emitting ear generated on average 1.9 emissions. Their peak sound-pressure levels lay between -5.8 and 10.3 dB, and their centre frequencies between 2.3 and 10.5 kHz. The SOAE originated primarily in the upper quarter

The time course of spontaneous otoacoustic emissions
European Archives of Oto-Rhino-Laryngology, 1992Spontaneous otoacoustic emissions (SOAEs) are amplitude-modulated pure sinus tones. The character of the sinus tone, which is a rare phenomenon in nature, can be proven by resolving the shifts and drifts that more or less always occur. In this report amplitude modulation was studied by digital filtering.

Spontaneous otoacoustic emissions in the guinea pig
Hearing Research, 1991Measurement of spontaneous otoacoustic emission (SOAE) in a large number of animals was conducted in the guinea pig. A remarkably high incidence of SOAE (51 ears out of 248 ears; 20.6%) was observed in the animals that were raised under unexceptional conditions.

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.

Phase coherence of spontaneous otoacoustic emissions derived from a cochlear model
Journal of the Acoustical Society of AmericaSpontaneous otoacoustic emissions (SOAEs) are commonly presented by averaging spectral magnitudes calculated in adjacent time segments of the recorded signal. To include the information carried by SOAE phase, Bergevin et al.
