Sweet Area Impulse Response Database

A dataset of acoustic impulse responses measured in the Immersive Media Lab (https://www.ikt.uni-hannover.de/de/institut/ausstattung/immersive-media-lab) listening room at the Institute of Communications Technology. Measurements were taken using a Neumann KU 100 dummy head and an mh acoustics em32 Eigenmike microphone array. The arrays were mounted on a robot arm and acoustic impulse responses in a spatial grid around the loudspeaker setup's sweet spot were measured using the ITA toolbox (https://www.ita-toolbox.org/). The setup consists of 42 loudspeakers. Version 1.0 of the dataset uses a custom Matlab struct format relying on itaAudio objects for storing the data. Conversion to the standardized SOFA format is planned. Details on the measurement setup are given in: Roman Kiyan, Stephan Preihs, Jürgen Peissig, “Robokopp: Robotic Setup for Automated Sweet Spot Measurements with Head Simulators and Microphone Arrays,” in Fortschritte der Akustik - DAGA 2024 (http://pub.dega-akustik.de/DAGA_2024/konferenz?article=614) The dataset is the basis of the analyses of the following papers: Roman Kiyan, Stephan Preihs, Jürgen Peissig, “Determining the immersion sweet area in multichannel loudspeaker reproduction using spatial sound field features,” presented at the Audio Engineering Society Convention 156 (http://aes2.org/publications/elibrary-page/?id=22520) Roman Kiyan, Stephan Preihs, Jürgen Peissig, “Signal dependencies of the immersion sweet area in multichannel loudspeaker reproduction,” TBA.本数据集为通信技术研究所（Institute of Communications Technology）下属沉浸式媒体实验室（Immersive Media Lab，https://www.ikt.uni-hannover.de/de/institut/ausstattung/immersive-media-lab）听音室内测得的声学冲激响应数据集。 本次测量采用Neumann KU 100人头仿真假头（dummy head）与mh acoustics em32 Eigenmike麦克风阵列完成。将麦克风阵列安装于机械臂之上，依托ITA工具箱（ITA toolbox，https://www.ita-toolbox.org/），在扬声器系统最佳听音区（sweet spot）周围的空间网格中采集声学冲激响应。该扬声器系统共包含42个扬声器。 本数据集V1.0版本采用自定义Matlab结构体格式，依托itaAudio对象存储数据，当前计划转换为标准化SOFA格式。 测量系统的详细信息参见以下文献： Roman Kiyan、Stephan Preihs、Jürgen Peissig：《Robokopp：用于人头仿真装置与麦克风阵列自动化最佳听音区测量的机械系统》，发表于《Fortschritte der Akustik - DAGA 2024》（http://pub.dega-akustik.de/DAGA_2024/konferenz?article=614） 本数据集为以下论文研究分析的核心基础： 1.
