对语音和音乐等复杂声音信号的感知依赖于外周和中枢听觉处理之间的相互作用。随着信息从耳蜗传递到初级和联合听觉皮质，传入的声音将受到越来越详细和精细的分析。这些不同级别的分析被认为包括低级别的自动过程，该过程检测、区分和分组在物理属性上相似的声音，如频率、强度和位置，以及反映听者对听觉环境的经验和知识的较高级别的图式驱动的过程。在这篇综述中，我们描述了使用事件相关脑电位来研究复杂声信号(例如，语音、音乐)的处理的研究。特别是，我们研究了听力损失对声音的神经表征的作用，以及认知因素和学习如何帮助补偿感知困难。听觉场景分析的概念被用作解释和研究声音知觉的概念框架。
The perception of complex acoustic signals such as speech and music depends on the interaction between peripheral and central auditory processing. As information travels from the cochlea to primary and associative auditory cortices, the incoming sound is subjected to increasingly more detailed and refined analysis. These various levels of analyses are thought to include low-level automatic processes that detect, discriminate and group sounds that are similar in physical attributes such as frequency, intensity, and location as well as higher-level schema-driven processes that reflect listeners' experience and knowledge of the auditory environment. In this review, we describe studies that have used event-related brain potentials in investigating the processing of complex acoustic signals (e.g., speech, music). In particular, we examine the role of hearing loss on the neural representation of sound and how cognitive factors and learning can help compensate for perceptual difficulties. The notion of auditory scene analysis is used as a conceptual framework for interpreting and studying the perception of sound.
