![]() Such language-based mechanisms include semantic and lexical expectations about words presented in context to facilitate speech perception in a noisy environment 4, 6, 7. To overcome this difficulty and facilitate speech perception, one strategically adopts some auditory and language-based compensatory mechanisms 5. Because of masking effects from background noise or a hearing problem, the acoustic speech signal is easily degraded, making it difficult to understand. Understanding external auditory speech normally and naturally requires at least two stages: auditory processing of the signal and language-based processing of that information 4. reported that approximately 17% of Korean adolescents exhibited at least slight HL 3. reported unilateral and bilateral HFHLs > 20 dB in 5.0% and 1.9%, respectively, of 1,658 adolescents aged 13–18 years in South Korea 2 and Rhee et al. Two nationwide studies have been conducted on adolescents in South Korea: Hong et al. In addition, chronic noise exposure from using mobile devices may increase high-frequency hearing loss (HFHL) 1. A study from the USA reported that the prevalence of HL among US adolescents increased from 14.9% in 1988–1994 to 19.5% in 2005–2006. With the increasing use of personal listening devices, the prevalence of hearing loss (HL) among the current generation of adolescents has been predictably higher than that among the past generations of adolescents. This study suggested that hearing loss, especially bilateral high-frequency hearing loss, may affect central auditory processing. We observed positive correlations among the APD questionnaire results and mean hearing levels. We analysed data from the Scale of Auditory Behaviors, Fisher’s Auditory Problems Checklist, and KNISE-Auditory Behavioral Checklist and compared these with the results of hearing tests. The prevalence of speech-frequency hearing loss (SFHL) and high-frequency hearing loss (HFHL) in the poorer ear was 11.6% and 10.3%, respectively, among Korean adolescents. The survey was sponsored by the Korean Society of Otolaryngology-Head and Neck Surgery and the Korean Otology Society. From June 1 to December 31, 2016, Korean adolescents (n = 2,791) in the first years of middle- and high school underwent audiometric testing and otologic examination and completed questionnaires on APD. This study aimed to investigate the prevalence of HL in students attending general middle- and high schools and compare the findings with the APD survey results. ![]() Auditory processing disorder (APD) is one of the main factors affecting academic achievement at school. Increasing use of personal listening devices has been accompanied by increase in the prevalence of hearing loss (HL) among youth in Korea, as in other countries. ![]()
