中文摘要
我们在日常交流中经历的声音会因环境不同而有很大差异。矛盾的是，提高声级可能导致言语感知变差，尤其是在噪声中。这种下降被称为“滚降”。目前尚不清楚滚降在不同年龄组以及有和无听力损失者中如何表现出差异。此外，越来越多的证据表明，聆听努力在困难的聆听条件下起重要作用，并可通过瞳孔扩张等客观指标直接量化。为了研究时间性、声级、背景噪声和努力对感知的交互影响，我们在多个声级下、安静和噪声环境中评估了年轻（≤25岁）和年长（>50岁）且无或患有轻度至中度听力损失的听者的词语识别。在这些测量过程中使用瞳孔测量法评估聆听努力。行为结果表明，滚降在时间性和非时间性言语对比中均发生。当言语在背景噪声中呈现时，滚降发生在年长正常听力听者和年长听力受损听者中。瞳孔测量结果表明，聆听努力受声级调节，并且更大的聆听努力主要发生在背景噪声存在时。声级增加对聆听努力的影响因年龄和听力损失而加剧，在年长听力损失听者中影响最大。滚降的年龄和听力依赖性效应凸显了高 sound levels 放大的潜在负面影响，因此对年龄相关性听力损失的有效治疗具有意义。
英文摘要
The sounds we experience in our everyday communication can vary greatly depending on the environment. Paradoxically, increasing the sound level may lead to worse speech perception, especially in noise. This decline is known as "rollover." It is unclear how rollover is experienced differentially across aging groups, as well as for those with and without hearing loss. In addition, there is mounting evidence that listening effort plays an important role in challenging listening conditions and can be directly quantified with objective measures such as pupil dilation. To investigate the interacting effects of temporality, sound level, background noise, and effort on perception, we assessed word identification at multiple levels and in quiet and in noise, in younger (≤25 years) and older (>50 years) listeners without or with mild-to-moderate hearing loss. Pupillometry was used to assess listening effort during these measurements. Behavioral results demonstrated that rollover occurred for both temporal and non-temporal speech contrasts. Rollover occurred in older normal-hearing and older hearing-impaired listeners when speech was presented in background noise. Pupillometry results demonstrated that listening effort was modulated by sound level and that greater listening effort was expended primarily in the presence of background noise. The effect of increased sound level on listening effort was exacerbated by age and hearing loss, with the greatest effect in older listeners with hearing loss. The age- and hearing-dependent effects of rollover highlight the potential negative impact of amplification of high sound levels and therefore has implications for effective treatment of age-related hearing loss.
