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.

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.

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".

Spontaneous otoacoustic emissions in two infants
Acta Oto-Laryngologica, 2009We regard spontaneous otoacoustic emission (SOAE) as a unique phenomenon due to spontaneous outer hair cell hyperactivity during the infantile period in these two infants.We report the cases of SOAEs in two infants, which were audible to their parents. We were able to hear continuous sounds from these two infants' ears. We studied their hearing and the

Spontaneous otoacoustic emissions: Measurement and data
Hearing Research, 1993Sounds from the ear canal were measured and then analyzed off-line. A peak-picking algorithm located spectral maxima which might be designated as spontaneous otoacoustic emissions (SOAEs). The output from a 0.5-cc syringe, used to stimulate the volume of the ear canal, was also measured, analyzed and used to approximate the false-alarm rate of the ...

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.

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.

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 monitor lizards
Hearing Research, 2004Monitors (all of which belong to the genus Varanus) make up a very uniform family of often large lizards. They have a large auditory papilla that is not highly specialized, but is divided into two unequal sub-papillae. All hair cells are covered by a tectorial membrane.

Spontaneous Otoacoustic Emissions in Different Racial Groups
Scandinavian Audiology, 1993To determine if there are racial differences in the prevalence of spontaneous otoacoustic emissions (SOAEs), both ears of 20 Negro, 20 Asian and 20 Caucasian subjects were examined for the presence of SOAEs. Within each racial group, equal numbers of normally hearing males and females were tested. Significant differences in the occurrence of SOAEs were
