Dataset for Improved detection of vowel eFFRs using HT2 analysis

Raw EEG data in .bdf format, collected using a 32-channel ActiveTwo EEG system (BioSemi, the Netherlands). EEG data were measured during presentation of words at an intensity of 70 dB SPL using ER-2 insert earphones. Stimuli were 4 random words, one presented each second, with an offset to onset inter-stimulus interval of at least 300 ms. Data are published in according with the EPSRC guidelines for data sharing.

本数据集包含采用荷兰BioSemi公司32通道ActiveTwo脑电图（Electroencephalogram, EEG）采集系统获取的.bdf格式原始脑电数据。实验过程中，通过ER-2插入式耳机以70分贝声压级（Sound Pressure Level, SPL）的强度呈现词语，同步采集脑电数据。实验刺激为4个随机词语，以每秒1个的频率呈现，且相邻刺激的偏移-启动间隔（offset-to-onset inter-stimulus interval）不低于300毫秒。本数据集的发布符合英国工程和物理科学研究委员会（Engineering and Physical Sciences Research Council, EPSRC）的数据共享规范。
