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
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

Interrelation of spontaneous and evoked otoacoustic emissions
Hearing Research, 1993The interrelation of spontaneous otoacoustic emissions (SOAEs) that can be synchronised by acoustic stimuli and transiently evoked otoacoustic emissions (TEOAEs) was studied in different experiments in normal ears. Click evoked TEOAEs mixed with synchronised SOAEs were investigated in time windows of 102.4 ms.

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.

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.

Incidence of spontaneous otoacoustic emissions in children and infants
Journal of the Acoustical Society of America, 1985Whereas some evidence indicates that spontaneous otoacoustic emissions (SOAEs) may be a manifestation of the normal functioning of an active feedback mechanism in the cochlea, other evidence suggests that emissions may be the result of the interaction of such a feedback mechanism with localized outer-hair-cell damage.

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 ...

The Influence of Spontaneous Otoacoustic Emissions on the Amplitude of Transient-evoked Emissions
Scandinavian Audiology, 1996The aim of the study was to analyse whether the presence of spontaneous otoacoustic emissions (SOAEs) in a group of normal-hearing adults is related to larger transient evoked otoacoustic emission (TEOAE) amplitudes when compared to a similar adult population without SOAEs. Twenty-four normal-hearing subjects participated in the investigation.

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 ...

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".
