background severe birth asphyxia (apgar < 7 at the 5th minute of birth) is recognized as a hearing loss risk factor by the joint committee on infant hearing (jcih). about half of the newborns with hearing loss do not indicate any sign and risk factor at birth. accordingly, the joint committee recommended performance of hearing screening test in 2000, especially for babies born with risk factors...
background noise most frequently affects hearing system, as it may typically cause a bilateral, progressive sensorineural hearing loss at high frequencies. objectives this study was designed to compare three different methods to evaluate noise-induced hearing loss (conventional audiometry, high-frequency audiometry, and distortion product otoacoustic emission). material and methods this was a c...
Neonates younger than the age of 12 weeks (10 full-term, 20 preterm) had an audiological assessment consisting of brainstem audiometry, tympanometry, transiently evoked otoacoustic emissions, and spontaneous otoacoustic emissions with contralateral white noise stimulation. Results from brainstem audiometry, tympanometry, and transiently evoked otoacoustic emissions suggested normal middle ear f...
This case was selected to highlight the importance of the test battery approach in the assessment of a child with auditory processing deficits. The utility of behavioral, electrophysiologic, acoustic immittance, and evoked otoacoustic emission procedures, as well as the problems associated with interpreting these multiple measures with differing results, is discussed. This case was confounded b...
Hum, a low-frequency subjective tone, aff ects approximately 2% of the population. Spontaneous otoacoustic emissions are sounds emitted from the inner ear, which in some cases are also perceived as tinnitus. The mechanisms of their generation, however, are still not well understood. In this paper, it is demonstrated that many properties reported by humsuff erers (derived from both questionnaire...
It has been reported that both click-evoked otoacoustic emissions (CEOAEs) and distortion product otoacoustic emissions (DPOAEs) have higher amplitudes in ears that possess spontaneous otoacoustic emissions (SOAEs). The general aim of the present study was to investigate whether the presence of spontaneous activity in the cochlea affected tone-burst evoked otoacoustic emissions (TBOAEs). As a b...
