The objective of this study is to determine whether presbycusis occurs much earlier than previously believed if the high frequency (above 8 kHz) are included. Tertiary referral center (a teaching University). This is a cross-sectional observational study. Healthy adults from 20 to 49 years of age who had essentially normal hearing were included into the study. They were subjected to high frequency pure tone audiometry (until 16 kHz). Participants were grouped based on age ranges of 10 years (e.g., 20-29, 30-39, and 40-49) and the presence of symmetrical high frequency sensor neural hearing loss were documented. There is a significant presence of symmetrical high frequency sensor neural hearing loss (not attributed to any known risk factors) as early as from the age group of 40 to 49 years. Seven of 43 participants (16%) from age group of 20 to 29 years and 12 of 24 participants (50%) from age group of 30 to 39 years had significant high frequency hearing loss. High frequency hearing loss (high frequency Presbycusis) may occur much earlier than previously believed.
本研究的目的是确定如果将高频（8kHz以上）纳入考量，老年性聋是否比之前认为的出现得更早。三级转诊中心（一所教学型大学）。这是一项横断面观察性研究。研究纳入了听力基本正常的20至49岁健康成年人。他们接受了高频纯音听力测定（直至16kHz）。参与者根据10岁的年龄范围分组（例如，20至29岁、30至39岁和40至49岁），并记录对称的高频感音神经性听力损失情况。早在40至49岁年龄组就有显著的对称高频感音神经性听力损失（并非由任何已知风险因素导致）。20至29岁年龄组的43名参与者中有7名（16%）以及30至39岁年龄组的24名参与者中有12名（50%）有显著的高频听力损失。高频听力损失（高频老年性聋）可能比之前认为的出现得更早。
