King–Kopetzky syndrome is an auditory disability characterised by difficulty in hearing speech in the presence of background noise in conjunction with the finding of normal hearing test results. It is an example of auditory processing disorder (APD) or ''auditory disability with normal hearing (ADN)''. King–Kopetzky syndrome patients have a worse Social Hearing Handicap index (SHHI) than others, indicating they suffer a significant degree of speech-hearing disability. The condition is named after Samuel J. Kopetzky, who first described the condition in 1948, and P. F. King, who first discussed the aetiological factors behind it in 1954. ==Causes== It seems that somatic anxiety and situations of stress may be determinants of speech-hearing disability.〔 Some studies indicated an increased prevalence of a family history of hearing impairment in these patients. The pattern of results is suggestive that King-Kopetzky patients may be related to conditions of autosomal dominant inheritance.〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「King–Kopetzky syndrome」の詳細全文を読む スポンサード リンク
