DESCRIPTION: This VA Career Development proposal is designed to support the development of the applicant into an independently funded VA research scientist investigating the contribution of central auditory encoding to successful rehabilitation of hearing impairment. The career plan is made up of coursework, publication and presentation of results, audiology clinic time, and mentoring from Drs. Marjorie Leek, Kelly Tremblay, and Harry Levitt. The long-term goal of this line of research is to improve perception in noise in older individuals and individuals with hearing loss. The specific goals of this study are to clearly demonstrate the physiological and behavioral signal-in-noise encoding abilities in hearing impaired and older individuals, and to use that understanding to explore how perception and neural encoding can be improved through speech-in-noise training. First, signal-to-noise ratio and background noise type will be varied to understand important factors and to establish a baseline in young normal-hearing individuals, older normal-hearing individuals and individuals with hearing loss. Then, speech-in-noise training will be administered and measured using both perception-in-noise tasks and cortical auditory evoked potentials. This combination of behavioral and physiological information will be used to determine the time course, generalization, and retention effects of speech-in-noise training.

描述： 该 VA 职业发展提案旨在支持申请人发展成为一名独立资助的 VA 研究科学家，研究中枢听觉编码对听力障碍成功康复的贡献。职业计划由课程作业、结果出版和展示、听力学诊所时间以及博士的指导组成。马乔里·利克、凯利·特伦布莱和哈里·莱维特。 该研究的长期目标是改善老年人和听力损失者对噪音的感知。这项研究的具体目标是清楚地证明听力受损者和老年人的生理和行为噪声中信号编码能力，并利用这种理解来探索如何通过噪声中语音训练来改善感知和神经编码。首先，将改变信噪比和背景噪声类型，以了解重要因素并为年轻听力正常个体、老年正常听力个体和听力损失个体建立基线。然后，将使用噪声中感知任务和皮质听觉诱发电位来管理和测量噪声中语音训练。这种行为和生理信息的组合将用于确定噪声中语音训练的时间进程、概括和保留效果。
