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.

项目概要/摘要 即使最近在早期识别听力损失方面取得了进展，患有轻度双侧听力损失的儿童 听力损失（MBHL）在沟通、社交和学业方面继续出现严重延迟 由于助听器对该人群的好处的不确定性而导致的结果。缺乏临床方案 对患有 MBHL 的儿童的听力需求敏感的工具加剧了这种不确定性。孩子们 根据目前的临床结果衡量，MBHL 患者的表现通常与听力正常的儿童相似。目标是 该提案旨在开发新的临床方案和工具，以应对所面临的挑战 患有 MBHL 的儿童。目前基于听力图的助听器候选标准没有充分量化 孩子的耳道声学和自身产生的噪音对其阈值的影响。目标 1 提案将是为患有 MBHL 的儿童开发基于听力的助听器候选工具，该工具占 耳道声学和自生噪声。新颖的听力学评估方法将允许 量化这些因素并制定基于语音的助听器候选标准 当前方法无法实现的可听度。该提案的目标 2 是验证临床措施 使用语音掩蔽器、混响和偷听来进行语音识别，反映了现实世界中的困难 患有 MBHL 的儿童。低强度声音的可听度降低是 MBHL 的主要后果， 这导致难以将目标说话者与背景说话者区分开来，难以理解噪声中的语音 存在混响，以及偷听远处谈话者的问题。临床语音识别任务反映 这些具体的听力挑战将得到开发和验证。该提案的目标 3 是执行 用于听力评估、助听器候选资格和结果的新型测试电池的临床验证 患有 MBHL 的儿童。该小说与美国领先的儿科听力学中心合作， 评估和语音识别措施将用于通过大型临床验证这些措施 患有 MBHL 的儿童人口。这项研究产生的知识将从根本上改善 儿童时期 MBHL 的诊断和治疗。
