目的：其目的是调查是否认知和/或听力学的措施预测辅助语音识别，频率压缩和不压缩（FC）。设计：参与者佩戴助听器（带和不带FC）总共12周（每个信号处理条件下六周，阿坝设计）。在每六周结束时评估噪音识别测试的表现。获得听力学（高频听力损失的严重程度、死区的存在）和认知（阅读广度和连线测试分数）测量值，并将其作为启用和未启用FC的噪声中识别的预测因子进行评估。研究样本：12名有经验的助听器使用者（年龄65-84岁），患有中度至重度高频听力损失，参加了这项研究。结果如下：结果表明，听觉和认知因素都可以预测噪声中的识别与常规放大。然而，只有听觉因素与从FC中获得的益处程度显著相关。结论：最强的预测辅助语音识别，无论有没有FC，是高频听力损失。认知表现也是常规放大获益的预测因子，但不是使用FC的额外获益的预测因子。
Objective: The aim was to investigate whether cognitive and/or audiological measures predict aided speech recognition, both with and without frequency compression (FC). Design: Participants wore hearing aids, with and without FC for a total of 12 weeks (six weeks in each signal processing condition, ABA design). Performance on a sentence-in-noise recognition test was assessed at the end of each six-week period. Audiological (severity of high frequency hearing loss, presence of dead regions) and cognitive (reading span and trail making test scores) measures were obtained and assessed as predictors of sentence-in-noise recognition with and without FC enabled. Study sample: Twelve experienced hearing-aid users (aged 65-84 years old) with moderate-to-severe high-frequency hearing loss took part in the study. Results: The results suggest that both auditory and cognitive factors can be predictive of sentence-in-noise recognition with conventional amplification. However, only auditory factors were significantly correlated with the degree of benefit obtained from FC. Conclusions: The strongest predictor of aided speech recognition, both with and without FC, was high frequency hearing loss. Cognitive performance was also a predictor of benefit from conventional amplification, but not of additional benefit from the use of FC.
