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

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
