BACKGROUND Otitis media (OM) is the most common paediatric illness for which antibiotics are prescribed. In Australian Aboriginal children OM is frequently asymptomatic and starts at a younger age, is more common and more likely to result in hearing loss than in non-Aboriginal children. Absent transient evoked otoacoustic emissions (TEOAEs) may predict subsequent risk of OM. METHODS 100 Abori...

Transient-evoked (TEOAE) and distortion-product otoacoustic emissions (DPOAE) were measured in 51 graduates of an intensive care nursery and compared to data obtained from 80 normal-hearing children and adults. All infants had click-evoked auditory brainstem responses (ABR) at 30 dB nHL or less while the older subjects had pure-tone thresholds of 20 dB HL or less for octave frequencies from 250...

introduction: to identify changes in oaes parameters in treatment course of idiopathic sudden sensorineural hearing loss (issnhl). materials and methods: in aprospective studyfromaugust 2005 to january 2009, 26 patients with issnhl underwent conventional audiometry/tympanometry and two types of oaes (teoaes and dpoaes) before and after the completion of standard drug therapy.the changes in pre-...

The development and application of otoacoustic emissions in clinical practice marked the beginning of a new era in the field of screening for congenital hearing loss. In particular, transient evoked otoacoustic emissions (TEOAEs) have been widely adopted by many universal hearing screening (UNHS) programs. The test is quick, non-invasive, objective, sensitive, frequency specific, relatively che...

The purpose of this study was to determine if the menstrual cycle influences the amplitude of transient (TEOAEs) and distortion-product (DPOAEs) otoacoustic emissions. Thirteen normal-hearing, normal-cycling females were monitored weekly for 12 weeks. TEOAE and DPOAE amplitudes were analyzed to determine if amplitude changes could be detected and correlated to phases of the menstrual cycle. No ...

AIM This study was designed to investigate the function of outer hair cells and medial olivocochlear efferents in type II diabetes mellitus (DM). MATERIALS AND METHODS There were 50 patients with type II DM and 51 age- and sex-matched healthy controls included in the study. Both groups were compared in terms of transient evoked otoacoustic emissions (TEOAEs), distortion product otoacoustic em...

The aim of this study was to compare the ratio of hearing loss evaluated with transient evoked otoacoustic emission (TEOAEs) testing in normal and hypertensive pregnant women during the first week after delivery. This was a prospective, case-control study. The hypertensive pregnancy group included 96 women with gestational hypertension preeclampsia, eclampsia, or HELLP syndrome, while the norma...

The purpose of the present investigation was to (1) determine the short-term test-retest reliability of the transient-evoked otoacoustic emission (TEOAE) parameters of echo level and reproducibility, as produced by the Otodynamic's ILO88 system; and (2) assess the ability of the ILO88 parameters of frequency spectrum, echo level, and reproducibility to identify ears with sensorineural hearing l...

This paper presents an application of the Hilbert–Huang transform (HHT) and ensemble correlation for detection of the transient evoked otoacoustic emissions (TEOAEs), and high resolution time–frequency mapping. The HHT provides a powerful tool for nonlinear analysis of nonstationary signals such as TEOAEs. Since the HHT itself does not distinguish between signal and noise it was used with ensem...
