全世界有超过3.6亿人患有致残性听力损失。其中大多数可以通过助听器治疗。不幸的是，助听器的性能和使用助听器的好处在不同的用户之间差别很大。在这里，我们调查了这种差异的原因。68名助听器使用者或候选人使用标准程序双侧安装非线性助听器。治疗结果通过测量在时间逆转的双说话背景下的辅助言语清晰度和自我报告的听力能力改善来评估。通过人口统计学和听力学数据、耳蜗机械功能障碍指标和听觉时间加工技能、助听器设置、工作记忆容量和预处理自我感知听力能力等19个预测指标的线性组合，获得这些结果的统计预测模型。较年轻的助听器使用者在安静环境下的辅助可理解性较好，且具有较好的时间加工能力。通过增加低强度声音的放大和使用更多线性放大来提高可理解性。自我报告的听力改善很难预测，但对于工作记忆能力较好的用户来说，听力改善的幅度往往较小。单独或结合听力设置的耳蜗机械功能障碍指标不影响预后预测。研究结果可能有助于改善助听器和设定患者的期望。
Over 360 million people worldwide suffer from disabling hearing loss. Most of them can be treated with hearing aids. Unfortunately, performance with hearing aids and the benefit obtained from using them vary widely across users. Here, we investigate the reasons for such variability. Sixty-eight hearing-aid users or candidates were fitted bilaterally with nonlinear hearing aids using standard procedures. Treatment outcome was assessed by measuring aided speech intelligibility in a time-reversed two-talker background and self-reported improvement in hearing ability. Statistical predictive models of these outcomes were obtained using linear combinations of 19 predictors, including demographic and audiological data, indicators of cochlear mechanical dysfunction and auditory temporal processing skills, hearing-aid settings, working memory capacity, and pretreatment self-perceived hearing ability. Aided intelligibility tended to be better for younger hearing-aid users with good unaided intelligibility in quiet and with good temporal processing abilities. Intelligibility tended to improve by increasing amplification for low-intensity sounds and by using more linear amplification for high-intensity sounds. Self-reported improvement in hearing ability was hard to predict but tended to be smaller for users with better working memory capacity. Indicators of cochlear mechanical dysfunction, alone or in combination with hearing settings, did not affect outcome predictions. The results may be useful for improving hearing aids and setting patients’ expectations.
