Abstract：
A model was developed to assess how elevated absolute thresholds and enlarged auditory filters can impede the ability to detect alarms in a noisy background, such alarms being of paramount importance to ensure the safety of workers. Based on previously measured masked thresholds of 80 listeners in five groups (normal hearing to strongly impaired), the model was derived from signal detection theory (SDT) applied to Glasberg and Moore\'s excitation pattern model. The model can describe the influence of absolute thresholds and enlarged auditory filters together or separately on the detection ability for normal hearing and hearing-impaired listeners with various hearing profiles. Furthermore, it suggests that enlarged auditory filters alone can explain all of the impairment in this specific alarm detection task. Finally, the possibility of further development of the model into an alarm detection model is discussed.
摘要：
开发了一个模型来评估升高的绝对阈值和扩大的听觉滤波器如何阻碍在嘈杂的背景下检测警报的能力。这种警报对于确保工人的安全至关重要。根据先前测量的5组80名听众的掩蔽阈值（正常听力到严重受损），该模型是根据信号检测理论（SDT）应用于Glasberg和Moore的激励模式模型得出的。该模型可以一起或分别描述绝对阈值和放大的听觉滤波器对具有各种听力特征的正常听力和听力受损听众的检测能力的影响。此外，它表明，扩大的听觉滤波器可以解释在这个特定的报警检测任务的所有损害。最后,讨论了将模型进一步发展为警报检测模型的可能性。
