听觉皮层在高级认知功能中起着至关重要的作用，包括对言语、音乐和听觉空间的感知。和其他感觉系统一样，大脑皮层的可塑性被用于对听觉系统进行微调，以实现这些更高的功能。耳蜗损伤后，听觉皮层的可塑性也可以被证明，它似乎参与了耳鸣的产生。早期的音乐训练导致听觉皮层对复杂和声的表达能力增强。同样，早期的语音环境对语言的发展也有很大的影响，可能对语言的皮层组织也有很大的影响。在听觉空间感知中，由头部和外耳产生的频谱线索在个体之间是不同的，必须通过扩孔来校准，这很可能发生在皮层水平。可塑性的神经机制可能在所有皮质区域都是相同的。因此，将一些关于听觉皮层可塑性的发现和假设与先前对其他感觉系统的研究联系起来应该是有用的。
The auditory cortex has a crucial role in higher cognitive functions, including the perception of speech, music and auditory space. Cortical plasticity, as in other sensory systems, is used in the fine tuning of the auditory system for these higher functions. Auditory cortical plasticity can also be demonstrated after lesions of the cochlea and it appears to participate in generating tinnitus. Early musical training leads to an expansion in the representation of complex harmonic sounds in the auditory cortex. Similarly, the early phonetic environment: has a strong influence on speech development and, presumably,on the cortical organization of speech. In auditory spatial perception, the spectral cues generated by the head and outer ears vary between individuals and have to be calibrated by reaming, which most probably takes place at the cortical level. The neural mechanisms of plasticity are likely to be the same across all cortical regions. It should be useful, therefore, to relate some of the findings and hypotheses about auditory cortical plasticity to previous studies of other sensory systems.
