本研究评估了轻度双侧或单侧听力损失（MBHL/UHL）儿童（8-12岁）在不同的听觉/视觉声学环境中定位和理解说话者的能力。检查了听力状态之间的潜在差异。参与者听到的句子由女性说话者从五个周围的位置在不同的声学环境。仅定位任务包括两个条件（听觉，视觉引导听觉）在三个声学环境（有利的，典型的，差）。参与者被要求找到每个说话者。言语感知任务包括在单个声学环境中的四个条件[仅听觉、视觉引导听觉、视听、仅听觉从0°方位角（基线）]。参与者被要求找到谈话者，然后重复所说的话。在仅定位任务中，参与者能够更好地定位说话者，并且在视觉指导下观看时间更短。在较差的声学环境中，正确的注视最差，注视时间最长。听力状态/年龄无显著影响。在言语感知任务中，视听条件下的表现最高，在视觉引导和仅视觉引导条件下的表现优于基线条件。虽然视听性能是最好的整体，儿童MBHL或UHL表现比同龄人NH更差。更好的耳朵纯音平均为儿童MBHL有更大的影响，关键字的理解比穷人耳朵纯音平均为儿童UHL。虽然孩子们可以更容易和更快地找到说话的视觉信息，发现单独的位置并没有改善言语感知。最好的言语感知发生在视听条件下，然而，MBHL或UHL儿童的表现较差，这表明能够看到说话者并不能克服听觉通路的减少。UHL儿童表现出更好的言语知觉比MBHL儿童，支持NH在至少一只耳朵的好处。
This study evaluated the ability of children (8–12 years) with mild bilateral or unilateral hearing loss (MBHL/UHL) listening unaided, or normal hearing (NH) to locate and understand talkers in varying auditory/visual acoustic environments. Potential differences across hearing status were examined. Participants heard sentences presented by female talkers from five surrounding locations in varying acoustic environments. A localization-only task included two conditions (auditory only, visually guided auditory) in three acoustic environments (favorable, typical, poor). Participants were asked to locate each talker. A speech perception task included four conditions [auditory-only, visually guided auditory, audiovisual, auditory-only from 0° azimuth (baseline)] in a single acoustic environment. Participants were asked to locate talkers, then repeat what was said. In the localization-only task, participants were better able to locate talkers and looking times were shorter with visual guidance to talker location. Correct looking was poorest and looking times longest in the poor acoustic environment. There were no significant effects of hearing status/age. In the speech perception task, performance was highest in the audiovisual condition and was better in the visually guided and auditory-only conditions than in the baseline condition. Although audiovisual performance was best overall, children with MBHL or UHL performed more poorly than peers with NH. Better-ear pure-tone averages for children with MBHL had a greater effect on keyword understanding than did poorer-ear pure-tone averages for children with UHL. Although children could locate talkers more easily and quickly with visual information, finding locations alone did not improve speech perception. Best speech perception occurred in the audiovisual condition; however, poorer performance by children with MBHL or UHL suggested that being able to see talkers did not overcome reduced auditory access. Children with UHL exhibited better speech perception than children with MBHL, supporting benefits of NH in at least one ear.
