Evaluation of the feasibility of using otoacoustic emissions in hearing screening in 6-13 year-old schoolchildren

Introduction. Otoacoustic emissions are weak acoustic signals
that can be measured in the ear canal. Their measurements
enable obtaining information on the status of the cochlea in the
inner ear. The most frequent application of otoacoustic emission
is screening of newborns for hearing loss.
Aim. The aim of the research was to study the properties of
otoacoustic emissions in primary school children (forms 0-6) and
evaluate the feasibility of the emissions as a screening test.
Material and methods. In total, 106 children aged 6-13
years were tested with click evoked otoacoustic emissions
(CEOAE). Each child was also examined by pure tone and
impedance audiometry. Reproducibility and signal to noise ratio
of otoacoustic emissions were analyzed and compared to the
results of pure tone audiometry.
Results. As much as 33% of the CEOAE results were
positive (that is, indicating a suspected hearing loss), while the
corresponding figures for pure tone and impedance audiometry
were 11% and 10%, respectively. Positive results in all three tests
coincided in 6% of all tested ears. Taking pure tone audiometry
as a reference, the sensitivity of the CEOAE test was evaluated
as 75% and its specificity as 73%.
Conclusions. In school aged children, CEOAE appears to
be a less effective test than pure tone audiometry because it
generates relatively high number of false positive results. On
the other hand, it could indicate that CEOAE is a more sensitive
test which may pick up even minor cochlear defects impossible
to detect by pure tone audiometry.
