Hearing loss and tinnitus are the two most common service-related disabilities among Veterans. These two conditions, together with the progressive effects associated with aging, present an important challenge for effective Veteran care. Furthermore, treatment of tinnitus and hearing loss has been shown to improve quality of life. Auditory rehabilitation for hearing loss commonly includes hearing aids as a means to improve audibility and allow access to important cues for accurate speech perception, which, in turn, promotes successful communication and engagement in psychosocial aspects of life. Hearing aids have also been found to reduce the bothersome ratings of those with tinnitus; in fact, some clinicians routinely fit hearing aids as a primary means of tinnitus treatment, in some cases even when hearing thresholds are within the normal range. In addition to the immediate audibility changes and treatment qualities related to acoustic modification made by the hearing aid, amplification also has the potential to affect higher level auditory processing abilities, such as speech perception in noise, cognition or other abilities required for complex listening tasks the effects (e.g., effort). Long-term effects of amplification, also known as acclimatization effects, are not well understood relative to more immediate audibility-related effects. A better understanding of the long-term acclimatization effects, together with more immediate audibility effects, will help audiologist to improve hearing aid success and benefit among Veterans. An approach using psychophysical, physiological, cognitive, and questionnaire outcome measures of both immediate audibility and long-term acclimatization effects that are associated with hearing aid use may help to clarify the positive impacts of amplification as a rehabilitation approach. The purpose of this study is to examine the way in which immediate audibility effects and long-term auditory processing effects of amplification affect a range of outcome measures. Improved measurement of the changes that occur with amplification will then help to understand and improve rehabilitation success.

听力损失和耳鸣是两种最常见的与服务相关的残疾 退伍军人。这两种情况，加上与衰老相关的渐进效应， 对有效的退伍军人护理提出了重要挑战。此外，治疗耳鸣和 听力损失已被证明可以改善生活质量。听力损失的听觉康复 通常包括助听器作为提高听力并允许访问重要内容的手段 准确的言语感知的线索，进而促进成功的沟通和 参与生活的社会心理方面。助听器也被发现可以减少 耳鸣患者的烦人评级；事实上，一些临床医生经常将助听器作为一种治疗手段。 耳鸣治疗的主要手段，在某些情况下，即使听力阈值在 正常范围。 除了与以下相关的即时听力变化和治疗质量之外 助听器进行的声学修改、放大也有可能影响 更高水平的听觉处理能力，例如噪声中的语音感知、认知或其他能力 复杂听力任务所需的能力影响（例如，努力）。长期影响 放大效应，也称为适应效应，相对于更多的效应，人们还没有很好地理解。 直接与可听性相关的效果。更好地了解长期适应环境 效果以及更直接的听觉效果将帮助听力学家改善听力 帮助退伍军人取得成功并从中受益。 使用心理物理、生理、认知和问卷结果的方法 相关的即时可听度和长期适应效果的测量 与助听器一起使用可能有助于阐明放大作为康复的积极影响 方法。本研究的目的是检验即时可听性效果的方式 放大的长期听觉处理效果会影响一系列结果指标。 改进对扩增发生的变化的测量将有助于理解 并提高康复成功率。
