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.

Correlated amplitude fluctuations of spontaneous otoacoustic emissions
The Journal of the Acoustical Society of America, 1998The frequency spectrum of a spontaneous otoacoustic emission (SOAE) recording may contain multiple narrow peaks. These peaks correspond to multiple SOAEs emitted by the inner ear. The individual SOAEs exhibit small amplitude fluctuations. The correlation between the amplitude fluctuations of multiple SOAEs in an individual ear was studied in 19 SOAE ...

Spontaneous otoacoustic emissions in seven frog species
Hearing Research, 1996Spontaneous otoacoustic emissions were screened for in five advanced frog species (Hyla cinerea, n = 10 ears; Hyla chrysoscelis, n = 10; Hyla versicolor, n = 7; Leptodactylus albilabris, n = 2; Rana pipiens pipiens, n = 8), and two primitive frog species (Xenopus laevis, n = 9; Bombina orientalis, n = 12).

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:Short-time Stability
Acta Oto-Laryngologica, 1992We have examined 307 spontaneous otoacoustic emissions (SOAEs) from 59 ears. The short-time amplitude stability was very good, especially in the high-frequency region. A statistically significant trend for emissions to influence other emissions could not be demonstrated.

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.

Temperature dependence of frog spontaneous otoacoustic emissions
The Journal of the Acoustical Society of America, 1987Spontaneous otoacoustic emissions are recorded from frog ears at various body temperatures. Frequency spectra and amplitude distributions of emissions are determined. Both power and frequency of emission signals show a strong temperature dependence.
