One of the practical problems of testing young children using evoked otoacoustic emissions (EOAEs) is that there is a need for the child to be quiet for a period of a minute or so. To achieve this can mean test periods of 10 min or longer. A new application of maximum length sequences (MLSs) to EOAEs is described that enables the test to be performed in a few seconds or less. Data from adults and neonates obtained at stimulation rates up to 840 clicks/s are presented and compared with conventionally derived emissions and the implications and applications of this new method are assessed.
使用诱发耳声发射（EOAE）测试幼儿时的一个实际问题是，需要幼儿安静大约一分钟左右。要做到这一点可能意味着测试时间长达10分钟或更长。本文描述了最大长度序列（MLS）在EOAE中的一种新应用，它能使测试在几秒或更短时间内完成。文中给出了在高达840次/秒的刺激率下从成人和新生儿获得的数据，并与传统方法得出的耳声发射进行了比较，同时评估了这种新方法的意义和应用。
