语音增强（SE）有助于听力，尤其是对患有年龄相关性听力损失的老年人。然而，增强后的语音质量（SQ）通常由听力正常的年轻听者评估，而他们的评分如何适用于老年人仍未得到充分探索。我们在筛选后，比较了40名年轻听力正常听者（20-30岁）和67名老年听者（60-95岁）的绝对语音质量评分，这些老年听者具有不同的听力图特征。测试材料包括具有真实背景的自然对话。对于年轻听者而言，语音增强系统之间清晰的语音质量差异在老年组中变得较小或无法区分，无论听力状况如何。听力损失的严重程度与较低的绝对评分相关，但并未强烈调节可区分语音质量差异的收缩。一小部分听力图混合的老年听者亚组表现出类似年轻听者的评分模式，这表明仅凭外周听力学无法解释这种收缩。
英文摘要
Speech Enhancement (SE) supports listening, particularly for older adults with age-related hearing loss. Yet, enhanced Speech Quality (SQ) is commonly evaluated by young normal-hearing listeners, and how their ratings translate to older adults remains under-explored. We compared absolute SQ ratings from 40 younger normal-hearing listeners (20-30 years) and 67 older listeners (60-95 years) with diverse audiometric profiles, after screening. Test materials comprised natural dialogues with realistic backgrounds. SQ differences between SE systems that were clear for younger listeners were smaller or inseparable in older groups, regardless of hearing status. Hearing loss severity was associated with lower absolute ratings, but did not strongly modulate the contraction in separable SQ differences. A small, audiometrically mixed subgroup of older listeners showed younger-like rating patterns, suggesting that peripheral audiology alone cannot explain the contraction.
