研究年轻人、中年人和老年人立即重复一段隐蔽的讲话信息会使他们受益。受试者在只有目标信息被重复的情况下，以及当目标信息及其掩饰(噪音或语音)都被重复的情况下，被试听句子。在后续实验中，使用方波调制噪声掩蔽器评估了重复的效果，以比较在第一次和第二次展示期间，听者接触到相同的目标信息时的好处，以及当一瞥不同时的好处。青年、中年人和老年人(n=16/组)为主要实验；15名年轻人为后续实验。当目标而不是掩蔽物对所有组重复时，重复受益更大。对于老年人来说尤其如此，这表明当背景信息重复时，这些人可能会受到更多负面影响。使用噪声掩蔽器获得的数据表明，当听者在最初的陈述和重复之间听到不同的(与相同的)语音部分时，它稍微更有好处。尽管在某些情况下发现了与年龄有关的细微差异，但结果证实，重复是一种有效的修复策略，适用于整个成年年龄范围的听者。
Toexamine benefit from immediate repetition of a masked speech message in younger, middle-aged and older adults. Participants listened to sentences in conditions where only the target message was repeated, and when both the target message and its accompanying masker (noise orspeech) were repeated. In a follow-up experiment, the effect of repetition was evaluated using a square-wave modulated noise masker to compare benefit when listeners were exposed to the same glimpses of the target message during first and second presentation versus when the glimpses differed. Younger, middle-aged, and older adults(n = 16/group) for the main experiment; 15 younger adults for the follow-up experiment. Repetition benefit was larger when the target but not the masker was repeated for all groups. This was especially true for older adults, suggesting that these individuals may be more negatively affected when a background message is repeated. Data obtained using noise maskers suggest that it is slightly more beneficial when listeners hear different (versus identical) portions of speech between initial presentation and repetition. Although subtle age-related differences were found in some conditions, results confirm that repetition is an effective repair strategy for listeners spanning the adult age range.
