本研究调查的因素，有助于赤字的老年人的听众在识别语音是退化的时间波形失真。对听力正常和轻度至中度倾斜感音神经性听力损失的年轻和老年听众进行了评估。来自噪声测试中的修订言语感知（R-SPIN）（Bilger，Nuetzel，Rabinowitz，& Rzeczkowski，1984）的低可预测性（LP）句子以未失真的形式和三种失真形式呈现给受试者：时间压缩，混响和中断。正确的识别分数表明，年龄和听力障碍独立的赤字在识别所有形式的时间失真的语音。此外，在时距辨别和间隙检测任务中评估了被试的听觉时间加工能力。典型相关程序表明，一些阈上的时间处理措施，特别是间隙持续时间的歧视，有助于识别混响语音的能力。总的结论是，年龄相关的因素以外的周边听力损失有助于降低老年人的语音识别性能。
This study investigated factors that contribute to deficits of elderly listeners in recognizing speech that is degraded by temporal waveform distortion. Young and elderly listeners with normal hearing sensitivity and with mild-to-moderate, sloping sensorineural hearing losses were evaluated. Low-predictability (LP) sentences from the Revised Speech Perception in Noise test (R-SPIN) (Bilger, Nuetzel, Rabinowitz, & Rzeczkowski, 1984) were presented to subjects in undistorted form and in three forms of distortion: time compression, reverberation, and interruption. Percent-correct recognition scores indicated that age and hearing impairment contributed independently to deficits in recognizing all forms of temporally distorted speech. In addition, subjects' auditory temporal processing abilities were assessed on duration discrimination and gap detection tasks. Canonical correlation procedures showed that some of the suprathreshold temporal processing measures, especially gap duration discrimination, contributed to the ability to recognize reverberant speech. The overall conclusion is that age-related factors other than peripheral hearing loss contribute to diminished speech recognition performance of elderly listeners.
