PROJECT SUMMARY/ABSTRACT Even with recent improvements in the early identification of hearing loss, children with mild bilateral hearing loss (MBHL) continue to experience significant delays in communication, social, and academic outcomes due to uncertainty about the benefits of hearing aids for this population. The lack of clinical protocols and tools that are sensitive to the listening needs of children with MBHL contribute to this uncertainty. Children with MBHL often perform like children with normal hearing on current clinical outcome measures. The goal of this proposal is to develop novel clinical protocols and tools that are sensitive to the challenges faced by children with MBHL. Current hearing-aid candidacy criteria based on the audiogram do not adequately quantify the effects of the child’s ear-canal acoustics and self-generated noise on their thresholds. Aim 1 of the proposal will be to develop audibility-based hearing-aid candidacy tools for children with MBHL that account for ear-canal acoustics and self-generated noise. Novel audiological assessment methods will allow for quantification of these factors and for the development of hearing-aid candidacy criteria based speech audibility that are not possible with current methods. Aim 2 of the proposal will be to validate clinical measures of speech recognition with speech maskers, reverberation, and overhearing that reflect real-world difficulties of children with MBHL. The reduction in audibility for low-intensity sounds is the main consequence of MBHL, which leads to difficulty segregating a target talker from a background talker, understanding speech in noise with reverberation, and problems with overhearing distant talkers. Clinical speech recognition tasks that reflect these specific listening challenges will be developed and validated. Aim 3 of the proposal will be to perform a clinical validation of a new test battery for hearing assessment, hearing-aid candidacy, and outcomes for children with MBHL. In collaboration with leading pediatric audiology centers around the U.S., the novel assessment and speech recognition measures will be used to validate these measures with a large clinical population of children with MBHL. The knowledge generated from this research will fundamentally improve the diagnosis and management of MBHL during childhood.

项目摘要/摘要 即使最近识别听力损失的近期改善，双侧的儿童也 听力损失（MBHL）继续在沟通，社交和学术方面遇到重大延迟 由于对助听器对该人群的好处的不确定性而产生的结果。缺乏临床方案 对MBHL儿童的听力需求敏感的工具会导致这种不确定性。孩子们 在MBHL的情况下，经常像在当前的临床结局指标上听力正常的儿童一样。目标 该建议是开发新颖的临床方案和工具，这些方案和工具对面临的挑战敏感 患有MBHL的孩子。基于听力图的当前助听器候选标准不能充分量化 孩子的耳朵声音和自我产生的噪音对阈值的影响。目标1 提案将是为MBHL儿童开发基于可听性的助听器候选工具 耳式声学和自我生成的噪音。新颖的听力学评估方法将允许 这些因素的数量以及基于助听器候选标准的演讲的发展 当前方法是不可能的。该提案的目标2将是验证临床措施 用语音掩盖者，混响和偷听的语音认可，反映了现实世界中的困难 患有MBHL的孩子。低强度声音的可听性降低是MBHL的主要结果， 这导致困难将目标说话者与背景说话者隔离，了解噪音中的语音 带着混响，并听到遥远的说话者的问题。反映的临床语音识别任务 这些具体的聆听挑战将得到开发和验证。提案的目标3将是执行 新的测试电池的临床验证，用于听力评估，助听器候选人以及结果 患有MBHL的孩子。小说与美国各地的小儿听力学中心合作 评估和语音识别措施将用于通过大型临床验证这些措施 MBHL儿童的人口。这项研究产生的知识将从根本上改善 童年时期MBHL的诊断和管理。
