The computer-averaged N1 response from humans to click stimuli was compared at three recording sites -- dermal and subdermal electrodes in the ear canal, and a transtympanic electrode on the promontory. A total of 26 subjects, some of whom were measured at all three sites, participated in 47 experiments. The promontory electrodes were consistently more sensitive and yielded cleaner N1 waveforms than did the ear canal sites. In considering the clinical use of N1 averaging, the advantages of the transtympanic method outweigh the risks. While a few persons yield reasonable good ear canal potentials, the reliablitity of this method in general application is inadequate and unpredictable.
对人类对点击刺激的计算机平均N1反应在三个记录部位进行了比较，即耳道内的皮肤电极和皮下电极，以及岬上的鼓室电极。共有26名受试者参与了47项实验，其中一些人在所有三个部位都进行了测量。岬电极始终比耳道部位更敏感，且产生的N1波形更清晰。在考虑N1平均的临床应用时，鼓室法的优点超过了风险。虽然少数人能产生相当好的耳道电位，但这种方法在一般应用中的可靠性不足且不可预测。
