人类听觉系统的临床评估是评估患者认知过程健康的一个组成部分。由听力学家进行的常规测试包括听觉稳态反应（ASSR）和听觉脑干反应（ABR），这两种测试都向患者呈现音频刺激，以便引起可通过脑电图（EEG）技术测量的大脑状态的变化。在听觉刺激评估期间对听觉皮层、颞叶皮层和脑干中的电生理活动的空间监测可用于精确定位听觉通路上的听觉功能障碍沿着的位置。然而，由于传统的听觉评估技术的侵扰性和缺乏信息的声音转导和耳蜗动力学通常无法恢复的脑电图，需要一个更好的方法来提高其临床实用性。在这里，我们提出了一种用于听觉健康评估的入耳式设备，该设备集成了用于刺激的声音引擎和用于实时同步记录大脑活动的高密度干电极EEG。该系统提供了易用性和患者舒适度。我们还研究了听觉系统的听觉传递功能，作为鼓膜，中耳骨和耳蜗子系统的复杂卷积。
Clinical assessment of the human auditory system is an integral part of evaluating the health of a patient's cognitive processes. Conventional tests performed by audiologists include the Auditory Steady State Response (ASSR) and the Auditory Brainstem Response (ABR), both of which present an audio stimulus to the patient in order to elicit a change in brain state measurable by electroencephalography (EEG) techniques. Spatial monitoring of the electrophysiological activity in the auditory cortex, temporal cortex, and brain stem during auditory stimulus evaluation can be used to pinpoint to location of auditory dysfunction along the auditory pathway. However, given the obtrusive nature of conventional auditory evaluation techniques and the lack of information about sound transduction and cochlear dynamics usually irrecoverable by EEG, a better approach is needed to improve its clinical utility. Here, we present an in-ear device for auditory health assessment that integrates a sound engine for stimulation and high-density dry-electrode EEG for real-time simultaneous recording of brain activity. This system provides ease-of-use and patient comfort. We also investigate the auditory transfer function of the hearing system as an intricate convolution of the tympanic membrane, middle ear bones, and the cochlear subsystems.
