Dataset of sauna impulse responses

PLEASE NOTE that the dataset was updated in February 2025! A dataset of impulse responses collected in the sauna at TUAS building of Aalto University, Espoo, Finland. The measurement setup included: Genelec 1030A loudspeaker with ampliefier removed external Quad 240 power amplifier (outside of the sauna) two Behringer ECM800 microphones seven custom-made temperature and humidity loggers, controlled with Arduino First 998 IRs were collected using 1-s sweeps, for the remaining 4201 IRs 2-s sweeps were used. For more information IR analysis please see the paper "Exploring Sauna Impulse Responses" by Karolina Prawda, Nils Meyer-Kahlen, and Sebastian J. Schlech in proceedings of Internoise 2024. How to read the files in the dataset: The general style of file naming is:IR_Sauna_test_meas_2023_03_30Thh_mm_ss_0300.wav, where hh is hours, mm is minutes, ss is seconds. For example, for IR measured at 12:55:01 the filename is:IR_Sauna_test_meas_2023_03_30T12_55_01_0300 The dataset is divided into two files, with IRs collected with 1-s and 2-s sweeps kept separately. Temperature_humidity_sauna_30_03_2023_upload.xslx contains the temperature and humidity data for the 7 sensors sauna.png contains a diagram showing the positions of microphones. loudspeaker, and the thermohygrometers. The dimensions along the Z-axis are: total height of the sauna 2.50m, loudspeaker 1.72m, near-field microphone: 1.67m, far-field microphone 1.95m, sensor 1: 0.69m, sensor 2: 1.52m, sensor 3: 1.02m, sensor 4: 0.68m, sensor 5: 1.35m, sensor 6: 1.59m, sensor 7: 1.01m. sauna_photo.png shows a photo of the measured sauna.请注意：本数据集于2025年2月完成更新！ 本数据集收录了芬兰埃斯波阿尔托大学（Aalto University）TUAS大楼桑拿房内采集的冲激响应（impulse response）数据。 本次测量的硬件配置包括： - Genelec 1030A型扬声器（移除内置放大器） - 外置Quad 240型功率放大器（放置于桑拿房外） - 两支Behringer ECM800型麦克风 - 七台定制化温湿度记录仪，由Arduino控制 前998条冲激响应采用1秒扫频信号采集，剩余4201条则采用2秒扫频信号采集。 如需了解更多冲激响应分析相关内容，请参阅Karolina Prawda、Nils Meyer-Kahlen与Sebastian J. Schlech发表于Internoise 2024会议论文集的《Exploring Sauna Impulse Responses》一文。 数据集内文件的命名规则如下： 文件命名通用格式为：IR_Sauna_test_meas_2023_03_30Thh_mm_ss_0300.wav，其中hh代表小时、mm代表分钟、ss代表秒。 例如，于12时55分01秒采集的冲激响应对应的文件名为：IR_Sauna_test_meas_2023_03_30T12_55_01_0300 本数据集分为两个部分，分别存储采用1秒扫频和2秒扫频采集的冲激响应数据。 文件Temperature_humidity_sauna_30_03_2023_upload.xslx存储了7台传感器的温湿度数据。 文件sauna.png为示意图，标注了麦克风、扬声器与温湿度记录仪的安装位置。 沿Z轴的尺寸参数如下：桑拿房总高度2.50米，扬声器安装高度1.72米，近场麦克风安装高度1.67米，远场麦克风安装高度1.95米，传感器1至7的安装高度分别为0.69米、1.52米、1.02米、0.68米、1.35米、1.59米与1.01米。 文件sauna_photo.png为本次测量的桑拿房实拍照片。
