A previous investigation demonstrated differences between younger adult normal-hearing listeners and older adult hearing-impaired listeners in the perceived emotion of clear and conversational speech. Specifically, clear speech sounded angry more often than conversational speech for both groups, but the effect was smaller for the older listeners. These listener groups differed by two confounding factors, age (younger vs. older adults) and hearing status (normal vs. impaired). The objective of the present study was to evaluate the contributions of aging and hearing loss to the reduced perception of anger in older adults with hearing loss. We investigated perceived anger in clear and conversational speech in younger adults with and without a simulated age-related hearing loss, and in older adults with normal hearing. Younger adults with simulated hearing loss performed similarly to normal-hearing peers, while normal-hearing older adults performed similarly to hearing-impaired peers, suggesting that aging was the primary contributor to the decreased anger perception seen in previous work. These findings confirm reduced anger perception for older adults compared to younger adults, though the significant speaking style effect-regardless of age and hearing status-highlights the need to identify methods of producing clear speech that is emotionally neutral or positive.
先前的一项调查表明，在清晰的对话式言语所传达的情感感知方面，年轻的听力正常的听众与年长的听力受损的听众之间存在差异。具体而言，对于这两组听众来说，清晰言语比对话式言语听起来更常带有愤怒情绪，但年长听众的这种效应较小。这两组听众在两个混杂因素上存在差异，即年龄（年轻人与年长者）和听力状况（正常与受损）。本研究的目的是评估衰老和听力损失对听力受损的年长者愤怒感知降低的影响。我们调查了有和没有模拟年龄相关性听力损失的年轻成年人以及听力正常的年长成年人在清晰言语和对话式言语中的愤怒感知情况。有模拟听力损失的年轻成年人的表现与听力正常的同龄人相似，而听力正常的年长成年人的表现与听力受损的同龄人相似，这表明衰老是先前研究中所观察到的愤怒感知降低的主要原因。这些发现证实了与年轻成年人相比，年长成年人的愤怒感知有所降低，尽管显著的说话风格效应——无论年龄和听力状况如何——凸显了识别出能够产生情感中立或积极的清晰言语的方法的必要性。
