DESCRIPTION (provided by applicant): Attention seems to play an important role in the ability of a listener to extract information from a complex environment. The first hypothesis to be tested is that auditory tasks performed in a complex environment require more attentional resources than in a simple environment. This will be tested by measuring the ability of listeners to perform one or more tasks in the presence of interfering sounds. By using the dual-task methodology, the costs of dividing attention between tasks will be quantified. The second hypothesis is that hearing impaired listeners must devote more attentional resources to equivalent auditory tasks - simple or complex - than must normal hearing listeners. A number of researchers have concluded, based on their research, that listeners with sensory-neural hearing loss have deficits that go beyond degraded sensory representations. If a normal hearing listener can perform a particular task with a given amount of attentional resources, it is possible that the amount of resources required for impaired listeners to do the same task is greater, in an amount correlated with the degree of hearing loss. By again employing the dual-task, the attentional resources used by hearing-impaired listeners will be compared with those used by normal-hearing listeners in the same tasks.

描述（由申请人提供）：注意似乎在听众从复杂环境中提取信息的能力中起着重要作用。要测试的第一个假设是，在复杂的环境中执行的听觉任务比在简单的环境中需要更多的注意力资源。这将通过测量听众在存在干扰声音的情况下执行一个或多个任务的能力来测试这一点。通过使用双任务方法，将量化任务之间的注意力成本。第二个假设是，听力受损的听众必须将更多的注意力资源投入到同等的听觉任务（简单或复杂）上，而不是正常的听众。根据他们的研究，许多研究人员得出结论，具有感官神经听力损失的听众的缺陷超出了降级的感官表征。如果正常的听力听众可以用给定的注意力资源执行特定任务，则可能受损的听众完成相同任务所需的资源数量更大，与听力损失程度相关。通过再次采用双重任务，将将听力受损的听众使用的注意力资源与正常听众在相同任务中使用的资源进行比较。
