Cochlear implants are increasingly used in the rehabilitation of the profoundly and totally deaf. Usually, insufficient gain of speech discrimination with a powerful conventional hearing aid is considered as a prerequisite for a cochlear prosthesis. With recent improvements of electronic systems, the criterion for this decision may change. To keep pace with the technical progress, a battery of speech sound tests suited for minimal auditory capabilities (MAC-battery) was developed and applied to groups of patients fitted with conventional instruments and with two different types of cochlear implants. Based on the comparison of the MAC-battery results of hearing aid groups, with the average performance of an implanted group, most conventionally fitted regular users of hearing aids should not be considered as candidates for cochlear implantation. The MAC-battery, although not a strictly standardized procedure, is a useful instrument for patient counselling and for the selection of implant candidates.
人工耳蜗越来越多地用于极重度和全聋患者的康复治疗。通常，使用大功率传统助听器时言语辨别增益不足被视为植入人工耳蜗的前提条件。随着电子系统的不断改进，这一决策标准可能会改变。为了跟上技术进步，开发了一套适合最小听觉能力（MAC电池组）的语音测试，并应用于佩戴传统器械和两种不同类型人工耳蜗的患者群体。根据助听器组MAC电池组结果与植入组平均表现的比较，大多数常规佩戴助听器的普通用户不应被视为人工耳蜗植入的候选人。MAC电池组虽然不是一个严格标准化的程序，但对于患者咨询和植入候选人的选择是一种有用的工具。
