听觉的基本感知单位是“听觉对象”。与视觉对象类似,听觉对象是听觉系统在声学环境中检测、提取、分离和分组频谱时间的能力的计算结果;我们周围的大量声学刺激一起形成听觉场景。然而,与视觉场景不同,解决听觉场景中的组件对象关键取决于它们的时间结构。听觉对象的神经相关性在整个听觉系统中被发现。然而,神经反应并不与听众的感知报告相关,直到皮层的水平。不同的神经结构的作用和不同的认知状态对听觉对象的感知的贡献尚未完全理解。
The fundamental perceptual unit in hearing is the ‘auditory object’. Similar to visual objects, auditory objects are the computational result of the auditory system's capacity to detect, extract, segregate and group spectrotemporal regularities in the acoustic environment; the multitude of acoustic stimuli around us together form the auditory scene. However, unlike the visual scene, resolving the component objects within the auditory scene crucially depends on their temporal structure. Neural correlates of auditory objects are found throughout the auditory system. However, neural responses do not become correlated with a listener's perceptual reports until the level of the cortex. The roles of different neural structures and the contribution of different cognitive states to the perception of auditory objects are not yet fully understood.
