Fountain sounds: Similarity and pleasantness assessments of water-fountain sounds recorded in urban public spaces_2015

This folder contains sound material and photographs used in the study:Rådsten Ekman, M., Lundén, P., and Nilsson, M.E. (2015). Similarity and pleasantness assessments of water-fountain sounds recorded in urban public spaces.The Journal of the Acoustical Society of America, 138, 3043-3052.doi: 10.1121/1.4934956Three types of files are included in the folder (32 of each type, one for each fountain):(1) *.wav These are mono wav-files used for sound analysis (e.g., Fig. 4 of the paper). The overall level of the sounds (LAeq,30s dB) is given in the file file_numbering.txt(2) *_B.wav These are B-format ambisonic files used in the listening experiment. See Section II.D. and Fig. 2 of the paper.(3) *.tifPhotos of the fountains. Photographers: Maria Rådsten Ekman & Peter LundénNote that the numbering of the fountains in the article corresponds to the first number of the names of the *.wav-files (so please ignore the second number that was used in an early stage of data collection). These numbers are the rank order of the sounds from most to least pleasant according to the group data of the listening test (see Sec. III.A. of the paper). In addition, three other files are included: (i) file_numbering.txtFile number and average A-weighted sound pressure level of the 30 s experimental sound (LAeq,30s) of each sound. Comma-separated text. Information on each variable is given in the head of the .txt file (rows indicated with #).(ii) recording_protocol.pdfTime of recordings and GPS-coordinates for each fountain may be found here, as well as other information about the recordings (some in Swedish).(iii) article_radsten_ekman_2015.pdfThis is the article.

本文件夹包含该项研究所用的音频素材与照片，对应论文：Rådsten Ekman, M.、Lundén, P. 与 Nilsson, M.E.（2015）发表于《美国声学学会期刊》（*The Journal of the Acoustical Society of America*）的《城市公共空间喷泉声的相似性与愉悦度评估》，卷138，页码3043-3052，DOI: 10.1121/1.4934956。

本文件夹共包含三类文件（每类各32个，一一对应一处喷泉）：
1. `*.wav`：单声道WAV音频文件，用于声学分析（例如论文中的图4）。各音频的30秒等效连续A计权声压级（LAeq,30s dB）详见`file_numbering.txt`文件。
2. `*_B.wav`：B格式环绕声（Ambisonic）文件，用于听觉实验，具体说明详见论文第二节D部分及图2。
3. `*.tif`：喷泉现场照片，拍摄者为Maria Rådsten Ekman与Peter Lundén。

需注意：论文中使用的喷泉编号与`*.wav`文件名的首位数字一致（请忽略数据收集早期阶段使用的第二位数字）。这些编号是依据听觉实验的组数据，按愉悦度从高到低对所有音频进行的排序（详见论文第三节A部分）。

此外，文件夹还包含三个额外文件：
(i) `file_numbering.txt`：逗号分隔的文本文件，记录了32段实验音频的编号与对应的30秒等效连续A计权声压级（LAeq,30s）。文件头部以`#`开头的行标注了各变量的详细说明。
(ii) `recording_protocol.pdf`：包含各喷泉的录制时间、GPS坐标及其他录制相关信息（部分内容为瑞典语）。
(iii) `article_radsten_ekman_2015.pdf`：本研究的完整论文原文。
