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.

has difficulty carrying on a telephone conversation and understanding loudspeaker messagesĬentral Auditory Processing Disorder (CAPD) may be hard to identify.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.has difficulty understanding oral instructions, particularly in noisy conditions.needs statements or instructions to be repeated and ask many questions.is easily distracted when there is background noise.has trouble listening and paying attention in a group.A child with Central Auditory Processing Disorder (CAPD) often: Typical behavioral signs in children with Central Auditory Processing Disorder (CAPD) may indicate the need for closer examination. Children with CAPDĬhildren with auditory difficulties are often wrongly diagnosed or seen to have learning disabilities. Central Auditory Processing Disorder (CAPD) may be associated with diseases, such as aphasia and Parkinson's. The cause of Central Auditory Processing Disorder (CAPD) may be genetic, but may also be associated with trauma at birth and middle ear infections resulting in temporary hearing loss. Researchers estimate that Central Auditory Processing Disorder (CAPD) is present in 3-5 percent of the population. Auditive training programmes may also be of benefit. However, assistive devices, such as FM equipment may alleviate some problems. People with Central Auditory Processing Disorder (CAPD) experience no immediate benefit from using a hearing aid. In other words, the brain cannot hear, even as the ears are fully functional. Their brains have difficulty discerning and processing the sounds. The problem is especially pronounced in situations with background noise. Even if their hearing is normal, people with Central Auditory Processing Disorder (CAPD) have difficulty understanding speech. To a person with Central Auditory Processing Disorder (CAPD) the sounds of speech are muddled together because the speech processing centers of the brain are unable to distinguish one speech sound from another.

Unilateral hearing loss - Single sided deafness.
