Abstract
ABSTRACT Objective: to evaluate the sensitivity and specificity of three hearing screening protocols: audiometry, tympanometry, and transient evoked otoacoustic emissions (TEOAE). Methods: a cross-sectional study comprising 70 schoolchildren aged 6-14 years old (9.9 ± 2). All participants underwent a complete audiological evaluation and screening procedures. Procedures were compared regarding sensitivity, specificity, and positive and negative predictive values. Results: sensitivity and specificity were, respectively, 64.71% and 66.04% for audiometry, 64.71% and 73.58% for tympanometry, and 66.67% and 78.85% for TEOAE. The positive and negative predictive values were 37.93% and 14.63% for audiometry, 44% and 13.33% for tympanometry, and 52.17% and 12.77% for TEOAE. Conclusions: in the school setting, TEOAE stands out from the two other screening protocols, in all measures regarding sensitivity, accuracy, and predictive values.

The purpose of this study is to investigate the sensitivity and specificity of audiometric, tympanometric, and transient evoked otoacoustic emissions (TEOAE) screenings when applied to the hearing screening of school-age children and adolescents
Summary
Hearing enables a child’s contact with the world of sound and language, in particular[1]. Hearing loss has a deleterious effect on speech and language development, as well as on academic performance[1,3], hindering social, emotional, and cognitive developing skills. The World Health Organization (WHO) estimates 466.46 million people have hearing loss worldwide, of which 34 million are children[4]. A recent study[6] showed a prevalence of 16.49% of children with hearing loss, mostly unilateral, mild, and in rural areas. Another study[7] noted the great variability in the prevalence of hearing loss in children, from 1.4% (regarding 29 countries) to 17.5% (Netherlands). It is evident that hearing loss in children is common[7] and has important impacts on their development
