External and middle ear status related to evoked otoacoustic emission
AN is mostly typified as missing or seriously abnormal auditory brainstem response and normal evoked otoacoustic emission
A correlative study of evoked otoacoustic emission
properties and audiometric thresholds.

Since 1993, research and publications[5-9] have supported universal screening; now the cost of identifying an infant with hearing loss is less than the cost of identifying an infant with phenylketonuria. Also, studies by Appuzzo and Yoshinaga-Itano and Yoshinaga-Itano and colleagues showed early identification and intervention improves language and social development, and today 37 states have more than 1 hospital providing universal hearing screening programs. A variety of screening devices are used, including automated auditory brainstem responses (AABR), transient evoked otoacoustic emission
, and distortion product otoacoustic emissions (DPOAE).
Audiometric pure-tone thresholds and transient evoked otoacoustic emission
(TEOAE) levels were determined in both groups.
All examinations were carried out by the same otolaryngologist, after which tympanogram, pure-tone audiometry (PTA), and transient evoked otoacoustic emission
(TEOAE) tests were conducted.
Hearing status in neonatal hyper bilirubinemia by auditory brain stem evoked response and transient evoked otoacoustic emission
. Acta Medica Iranica 2011; 49 (2) 109-112.
Prior to the start of the study, baseline measurements of transient evoked otoacoustic emission
(TEOAE) and auditory brainstem response (ABR) were obtained in all subjects.
Identification of neonatal hearing impairment: evaluation of transient evoked otoacoustic emission
, distortion product otoacoustic emission, and auditory brain stem response test performance.
The transient evoked otoacoustic emission
and distortion product otoacoustic emission responses of 38 children with autism were investigated and compared with those of 27 typically developing control subjects.
A study conducted by the National Institutes of Health , detected that the TOAE are affected depending on the frequency, since the levels of noise are louder when the frequencies tested are lower, making it more difficult to detect the presence of an evoked otoacoustic emission
with spectrum under 1.500 Hz.
