Project Summary Speech in noise tests have traditionally involved 1) unrealistic maskers such as broadband noise presented from the same spatial location as the target speech, and 2) unengaging reward structures. Our overarching hypothesis is that the experience of listeners in their daily lives will be more strongly related to performance if the laboratory tests are enhanced by increasing the realism of the testing environments and introducing game- like interfaces. The main goal of this project is to determine which enhancements have the greatest impact on the relationship with listener complaints, and which listener abilities (auditory and cognitive) mediate and modulate this relationship. Enhanced environments will be tested that 1) simulate real-world experiences by conducting assessments in synthetic environments that include both auditory and visual stimuli and 2) introduce game-like elements that are more rewarding and motivating for the listener. Understanding how different participants respond to a variety of enhancements will provide essential new information about the ways in which realistic experiences differ from traditional laboratory tests and the ways that rewards and motivation influence variability of test results as well as relationships with self-report. Experiments will involve younger listeners with normal hearing, older listeners with a range of hearing abilities from normal to severely impaired, and a group of listeners with a history of mild traumatic brain injury. These participants will provide a wide range of performance on measures of auditory and cognitive abilities, which can then be used to better understand any effects of the enhancements on self-reported ability to function in complex listening environments. Upon completion of this project there will exist, freely available, an extensive set of enhanced auditory assessments that are more engaging and more realistic than what is currently available and that run on inexpensive consumer-grade equipment. This project will establish for these enhanced tests both 1) established ranges of normal performance as a function of age and hearing loss, and 2) known relationships to various established tests of speech in noise. The modeling work associated with this project will reveal which auditory and cognitive abilities are associated with deviations from normal performance and self-reported difficulties hearing in adverse listening environments that are great than would be expected.

项目摘要 传统上，噪声测试中的语音涉及1）不切实际的掩蔽器，例如宽带噪声 从与目标语音相同的空间位置，以及2）不参与的奖励结构。我们的总体 假设是，听众在日常生活中的经历将与表现更加密切 通过增加测试环境的现实主义并引入游戏 - 喜欢界面。该项目的主要目标是确定哪些增强功能对 与听众投诉的关系，听众能力（听觉和认知）中介和 调节这种关系。将测试增强的环境，1）通过 在包括听觉和视觉刺激的合成环境中进行评估以及2） 介绍类似游戏的元素，对听众来说更有意义和激励。了解如何 不同的参与者对各种增强的反应将为有关 现实经验与传统实验室测试不同的方式以及奖励和奖励的方式 动机会影响测试结果的变异性以及与自我报告的关系。实验将涉及 年轻的听众，听力正常，年长的听众从正常到严重 受损，一群听众有轻度脑损伤的病史。这些参与者将提供 在听觉和认知能力的度量方面的性能广泛，然后可以用来更好 了解增强功能对自我报告的复杂聆听功能的能力 环境。该项目完成后，将有一套广泛的增强 听觉评估比当前可用的更具吸引力和更现实的评估 在廉价的消费级设备上。该项目将为这些增强测试建立1） 建立正常性能的范围是年龄和听力损失的函数，以及2）已知关系 噪音中各种既定的语音测试。与该项目相关的建模工作将揭示哪个 听觉和认知能力与正常表现的偏差和自我报告有关 在不利的听力环境中听到的困难比预期的很大。
