Preference ratings and 32 magnitude frequency response curves

This repository comprises two CSV files: PreferenceRatings and MagnitudeFrequencyResponses. The former includes preference ratings obtained from 56 naive assessors (30 Danish---DK, 26 Japanese---JP) of 32 headphone curves over several music programs in several trials. The latter includes the magnitude frequency response curves evaluated by the assessors, expressed as gains of a 30-band graphic equalizer whose bands are centered between 31 Hz and 25 kHz. The curves were either derived from eight popular closed circumaural headphones, measured with a Brüel & Kjær Head and Torso Simulator 5128C, or otherwise obtained from the literature. The details of the methods, results, etc. are published in [1]. [1] G. Ravizza, J. Villegas, T. Stegenborg-Andersen, and C. P.

Conv., Oct 2023.本数据集仓库包含两份CSV格式文件：偏好评分表（PreferenceRatings）与幅度频率响应表（MagnitudeFrequencyResponses）。前者收录了56名非专业评估者（30名丹麦籍——DK、26名日本籍——JP）针对32条耳机频响曲线，在多组测试音乐片段与多轮试验中给出的主观偏好评分。后者收录了经上述评估者评价的幅度频率响应曲线，该类曲线以30段图形均衡器的增益值形式表征，其频段中心频率覆盖31 Hz至25 kHz区间。曲线的获取途径分为两类：其一源自8款主流封闭式包耳式头戴耳机，采用布鲁埃尔与凯雅（Brüel & Kjær）5128C型人头躯干模拟器（Head and Torso Simulator 5128C）实测得到；其二从已发表的学术文献中获取。本数据集的研究方法、实验结果等详细信息已发表于文献[1]。[1] G.
