Electrical auditory middle latency responses (EAMLRs) were recorded in a group of 12 postlingually and 4 congenitally deaf cochlear implant users. The EAMLRs of the postlingually deaf cochlear implant users were compared to behavioral measures of speech perception. All the cochlear implant users showed pronounced EAMLR morphology and amplitude. EAMLRs of congenitally deaf cochlear implant users were remarkably similar to those of postlingually deaf cochlear implant users. The difference in speech perception ability between congenitally deaf and postlingually deaf cochlear implant users did not seem to be caused by integrity differences of the neural generators of the auditory middle latency response. For the postlingually deaf subjects, EAMLR amplitude variation and interlatency variation seemed to be related to specific aspects of speech perception. The poorer performers demonstrated more diversity in the amplitude of the EAMLR component peaks and a more diffuse EAMLR peak latency organization across the electrodes than the better performers.
对一组12名语后聋和4名先天性聋的人工耳蜗使用者记录了电听觉中潜伏期反应（EAMLRs）。将语后聋人工耳蜗使用者的EAMLRs与言语感知的行为测量结果进行比较。所有人工耳蜗使用者均表现出明显的EAMLR形态和振幅。先天性聋人工耳蜗使用者的EAMLRs与语后聋人工耳蜗使用者的非常相似。先天性聋和语后聋人工耳蜗使用者在言语感知能力上的差异似乎并非由听觉中潜伏期反应神经发生器的完整性差异所致。对于语后聋受试者，EAMLR振幅变化和潜伏期变化似乎与言语感知的特定方面有关。表现较差者与表现较好者相比，EAMLR成分峰值的振幅更具多样性，且跨电极的EAMLR峰值潜伏期组织更分散。
