Journal of the Acoustical Society of America, 2016
An objective technique based on the time-frequency analysis of otoacoustic emissions is proposed to get fast and stable estimates of cochlear tuning. Time-frequency analysis allows one to get stable measurements of the delay/frequency function, which is ...

A review of otoacoustic emissions
The Journal of the Acoustical Society of America, 1991Otoacoustic emissions measured in the external ear canal describe responses that the cochlea generates in the form of acoustic energy. For the convenience of discussing their principal features, emitted responses can be classified into several categories according to the type of stimulation used to evoke them.

Otoacoustic emissions are low-intensity sounds that are produced in the cochlea and transmitted through the middle ear apparatus to the ear canal. They can be detected and extracted from the background noise in the ear canal through the use of a sensitive microphone and selective filtering or averaging techniques.

Journal of the American Veterinary Medical Association, 1991
A 7-month-old female Poodle was evaluated for a sound continuously emanating from its left ear. The frequency and intensity of the tone was matched by use of a multifrequency audiometer. The frequency and intensity of the sound were 9,594 Hz and 45.5 decibels sound pressure level, respectively.

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.

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.

Resonant modes of otoacoustic emissions
Physiological Measurement, 2007Transiently evoked otoacoustic emission (TEOAE) signals were decomposed into basic components by means of the matching pursuit algorithm. The components were characterized by frequency, latency, time span and energy. The resonant modes characteristic for each person/ear were identified.

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.

Mechanisms of Mammalian Otoacoustic Emission and their Implications for the Clinical Utility of Otoacoustic Emissions [PDF]
Ear and Hearing, 2004 We review recent progress in understanding the physical and physiological mechanisms that generate otoacoustic emissions (OAEs). Until recently, the conceptual model underlying the interpretation of OAEs has been an integrated view that regards all OAEs as manifestations of cochlear nonlinearity.

Otoacoustic emissions in patients with hypotension
The Journal of Laryngology & Otology, 2003The aim of this study was to investigate the relation between hypotension and slowly developing hearing impairment, using otoacoustic emissions. A group of 42 patients was examined, with diastolic blood pressure ≤60 mmHg and systolic blood pressure ≤105 mmHg.
