摘　　要：听力筛查设备被广泛应用干新生儿听力筛查，其量值的准确和统一直接影响着听力筛查结果的准确性。本文首先对与听力筛查设备计量相关的国际和国内标准进行了分类，然后详细介绍了标准中对耳声发射测量仪、听性脑干反应测量仪技术参数的要求以及短时程信号的听力零级问题，最后总结了听力筛查设备在使用和计量中的现状以及存在的问题。Audiometric equipment is widely used in newborn hearing screening and the accuracy and consistency of the values directly affect the quality of the results of hearing screening. In this article, the international and domestic standards for the measurement of the hearing screening equipment are introduced and classified. And the technical parameters requirements for otoacoustic emission devices and auditory brainstem response devices are stated and the hearing zero level standards for short duration stimulus signals are also described. Finally, the current status and existing problems of the application and measurement of the hearing screening equipment are summarized.
