SA-PN-TEC: Pink noise sounds and EEG files

Pink noise sounds with a length of 2.73 seconds calibrated to three headphone models: Atvio® supra-aural headphones, Shure® SRH1840 circum-aural headphones, and Apple® EarPods® intra-aural headphones. Sample rate: 44100Hz. Electrophysiological data in GDF format of 30 individuals listening to pink noise for five minutes before and after 30 days of daily exposure. There are 29 available datasets for the first session and 25 for the last session. Sample rate: 250 Hz. Electroencephalography was used for the recording of the brain activity. Text files with electrode positions, ID of recordings, heart rate, sex of subjects and groups.时长为2.73秒的粉红噪声（Pink noise），已针对三款耳机型号完成校准：Atvio®压耳式头戴耳机、Shure® SRH1840包耳式头戴耳机及Apple® EarPods®入耳式耳机。采样率为44100Hz。 30名受试者在为期30天的每日粉红噪声暴露前后，各聆听5分钟粉红噪声时的GDF格式电生理数据。首轮实验可获取29份数据集，末轮实验可获取25份数据集。 采样率为250Hz。实验采用脑电图（Electroencephalography）技术记录大脑活动。 文本文件包含电极位置、录音ID、受试者心率、受试者性别及分组信息。
