Evoked and spontaneous otoacoustic emissions
Brain and Development, 1993Evoked otoacoustic emissions (EOAEs) and spontaneous otoacoustic emissions (SOAEs) were compared between neonates and adults. Several differences were seen for EOAEs: (i) the occurrence of EOAEs was significantly greater in adults than in neonates, and in neonates it increased with extra-uterine age; (ii) the high frequency EOAE intensity was greater ...

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

Longitudinal measurements of spontaneous otoacoustic emissions in infants
The Journal of the Acoustical Society of America, 1994It has previously been shown [E. M. Burns, K. H. Archart, and S. L. Campbell, J. Acoust. Soc. Am. 91, 1575–1581 (1992)] that both the overall prevalence of spontaneous otoacoustic emissions (SOAEs) and most of the various gender- and ear-related prevalence tendencies are not significantly different in 1-month-olds and adults. However, large differences

Aspects of spontaneous otoacoustic emissions in healthy newborns
Hearing Research, 1993Spontaneous otoacoustic emissions (SOAEs) are pure-tone like signals, spontaneously present in the ear canal. In normal adult ears the prevalence of SOAEs is reported to be 30-70%, probably depending on the noise floor of the recordings. In infant studies, results on the SOAE prevalence are rare.

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.

Effects of External Stimuli on Spontaneous Otoacoustic Emissions
Ear and Hearing, 1988The behavior of spontaneous otoacoustic emissions (SOAEs) is affected by external stimuli. A series of experiments was conducted with 25 normal-hearing subjects to explore multiple and bilateral SOAEs, frequency and amplitude drift of SOAEs, suppression functions and existence regions for distortion products generated by the interaction of SOAEs and ...

Amplitude and frequency fluctuations of spontaneous otoacoustic emissions
The 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 idiotone and spontaneous otoacoustic emissions
The Journal of the Acoustical Society of America, 1997Although the preponderance of Dix Ward’s work was in the area of the effects of noise on hearing, his paper on tonal monaural displacusis [J. Acoust. Soc. Am. 27, 365–372 (1955)] has always been my favorite from among all of his papers. In this paper, published several years after he had completed his work at Harvard and was being introduced to noise ...

An automated procedure for identifying spontaneous otoacoustic emissions
The Journal of the Acoustical Society of America, 2000An algorithm is described for objectively identifying and measuring spontaneous otoacoustic emissions (SOAEs) using the spectrum that results from transformation of the acoustic waveform measured in the outer ear canal. Prior to spectral analysis, the rms level is calculated for successive short segments of the waveform and only the weakest 25% of the ...
