Hearing loss in school-age children can affect learning, speech perception, social skill development, and self-image. To examine hearing-loss prevalence and trends in adolescents, researchers compared audiometric hearing evaluations in 2928 teens (age range, 12–19 years) in the Third National Health and Nutrition Examination Survey (NHANES III, 1988–1994) with evaluations in 1771 teens in the NHANES 2005–2006 survey.

Most hearing loss was unilateral, and high-frequency hearing loss was more common than low-frequency loss in both surveys. Prevalence of mild or worse hearing loss (>25 dB) also wa…
