由两个单独的古怪音调序列分别呈现给右耳和左耳的事件相关电位可以用来实现听觉脑机接口来检测选定的注意。为了提高模式分类的准确率，本研究检测了奇怪的声调序列诱发的事件相关电位，并研究了数据的预处理方法(空间滤波、频率滤波和下采样)。结果表明，对测量数据进行下采样(100赫兹)对所有六个被试的分类精度都有显著的提高(85%以上)。
Event-related potentials elicited by two individual oddball tone sequences presented to both right and left ears can be used to realize auditory BCI to detect selected attention. In this study, event-related potentials elicited by oddball tone sequences were examined and the methods to pre-process the data (spatial filter, frequency filter and down sampling) were investigated to improve pattern classification accuracies. As a result, it was shown that the down sampling (100 Hz) of the measured data was prominent for improving the classification accuracies (over 85%) in all of six subjects.
