本文报道了171名老年助听器佩戴者的辅助和非辅助语音识别得分。所有助听器佩戴者都配备了相同的仪器（带输出限制压缩的线性d类放大器），并使用标准方案进行评估。除了包括语音识别的多种测量，一套广泛的听觉功能的生理和知觉测量，以及认知功能的一般测量，在助听器安装之前完成。本研究结果与现有规范的比较表明，这组参与者的听力损失和年龄相当典型或具有代表性。所研究的预测一般语音识别性能的方法包括基于声学指数、语音可理解性指数（SII）和其他基于线性回归统计分析的方法。后一种方法被证明是最成功的，约占语音识别性能差异的三分之二，主要预测因素是听力损失和认知功能的测量。(C) 2002美国声学学会。
This paper reports the aided and unaided speech-recognition scores from a group of 171 elderly hearing-aid wearers. All hearing-aid wearers were fit with identical instruments (linear Class-D amplifiers with output-limiting compression) and evaluated with a standard protocol. In addition to including multiple measures of speech recognition, an extensive set of physiological and perceptual measures of auditory function, as well as general measures of cognitive function, were completed prior to the hearing-aid fitting. Comparison of the results from this study to available norms suggested that this group of participants was fairly typical or representative for their hearing loss and age. Approaches to the prediction of general speech-recognition performance that were examined included methods based on an acoustical index, the Speech Intelligibility Index (SII), and others based on linear-regression statistical analysis. The latter approach proved to be the most successful, accounting for about two-thirds of the variance in speech-recognition performance, with the primary predictive factors being measures of hearing loss and cognitive function.
