Dataset: Changes in Tinnitus by chochlear implantation

raw data to reproduce figure 2 of the paper: CHANGES IN TINNITUS BY COCHLEAR IMPLANTATION: A PARAMETRIC STUDY OF THE EFFECT OF SINGLE-ELECTRODE STIMULATION.
We performed a listening experiment in 19 adult participants, who had received a unilateral cochlear implant (CI) because of severe bilateral hearing loss. All of these patients had indicated that they suffered from tinnitus. During a 300-s interval, patients listened to blocks of single-electrode stimulation and rated the loudness of the stimulus and any effects on their tinnitus. The 300-s interval included a block of single-electrode stimulation (duration 120 s). In consecutive intervals, the stimulus differed in its cochlear location (basal or apical), its pulse rate (720 or 725 Hz, 1,200 Hz, and 2,400 or 2,320 Hz), and amplitude (just above threshold or equivalent to moderate loudness). Thus, 2 × 3 × 2 = 12 stimulus conditions were tested in each participant, and each condition was presented only once. During the experiment, the participants promptly rated the loudness of the stimuli and the loudness of their tinnitus on a Visual Analogue Scale (10-point VAS).

本数据集用于复现论文《人工耳蜗植入术后耳鸣的变化：单电极刺激效应的参数化研究》（CHANGES IN TINNITUS BY COCHLEAR IMPLANTATION: A PARAMETRIC STUDY OF THE EFFECT OF SINGLE-ELECTRODE STIMULATION）的图2。本研究开展了一项听觉聆听实验，纳入19名因双侧重度听力损失接受单侧人工耳蜗（Cochlear Implant, CI）植入的成年受试者，所有受试者均自述患有耳鸣。实验单轮时长为300秒，受试者需聆听单电极刺激序列，并对刺激响度及耳鸣受影响的情况进行评分，该300秒实验时段包含一段时长120秒的单电极刺激区块。在连续的实验轮次中，刺激参数存在差异，包括耳蜗刺激位置（基底侧或尖顶侧）、脉冲率（720或725 Hz、1200 Hz、2400或2320 Hz）以及刺激强度（刚高于听阈或对应中等响度）。因此，每名受试者共需完成12种刺激条件的测试（2×3×2=12），且每种条件仅呈现一次。实验过程中，受试者需通过10分量表视觉模拟量表（Visual Analogue Scale, VAS）即时评定刺激响度与自身耳鸣响度。
