DESCRIPTION (provided by applicant): Our remarkable capacity to process information in sound is demonstrated everyday as we make sense of the continuous pattern of variation in the acoustic signals we encounter. The long-term goal of this project is to better understand this ability in normal-hearing adults through controlled measures of their ability to detect and discriminate variation in acoustic patterns made up of tones. There are three key elements of our approach. First, all efforts are linked by a single theoretical framework where the information in the patterns is given precise meaning and listener performance is evaluated relative to a common performance standard. Second, the manner in which different internal factors influence the listener's response is determined from trial-by:trial analyses of the data. Third, specific hypotheses regarding the outcome of experiments are generated based on known nonlinear transformations performed at the auditory periphery and a decision model that has made accurate predictions for the results of many past studies [R.A. Lutfi, J. Acoust. Soc. Am. 94, 748-758 (1993)]. Present aims are to: (1) measure auditory nonlinearity in the discrimination of pure-tone frequency, intensity and duration (2) determine the specific influence of auditory nonlinearity, listener decision weights, and internal noise on the integration of information across frequency and time, and (3) demonstrate successful achievement of aims by maximizing information rate through stimulus design. By advancing our understanding of the normal adult capacity to process information in sound the results may prove key in the development of technologies and rehabilitative strategies that deal more effectively with the impact of dysfunctional hearing on everyday listening.

描述（由申请人提供）：我们每天都会证明我们在声音中处理信息的显着能力，因为我们了解遇到的声学信号的连续变化模式。该项目的长期目标是通过受控措施检测和区分由音调组成的声学模式变化的能力来更好地理解正常听力的成年人的能力。我们的方法有三个关键要素。首先，所有努力都与单个理论框架联系在一起，在该框架中，模式中的信息具有精确的含义，并且相对于共同的性能标准评估了听众的性能。其次，不同的内部因素影响听众的响应的方式是由试用：数据的试验分析。第三，关于实验结果的特定假设是基于在听觉外围进行的已知非线性变换以及对过去许多研究结果进行准确预测的决策模型生成的[R.A. Lutfi，J。Acoust。 Soc。是。 94，748-758（1993）]。目前的目的是：（1）在隔离频率，强度和持续时间（2）歧视中测量听觉非线性（2）确定听觉非线性，听众决策权重以及内部噪声对跨频率和时间整合的内部噪声的特定影响，（3）通过通过刺激速率来最大化目标的成功实现目标。通过促进我们对正常成人处理声音中信息的能力的理解，结果可能是技术和康复策略的开发，这些策略更有效地处理功能失调的听证会对日常聆听的影响。
