Binaural Room Impulse Responses: Same Listener-Source-Setup At Different Positions In The Room

To study the perception of room acoustics in dependency of the position in the room, measurements with KEMAR head-and-torso-simulator were conducted. The dummy head was placed at 5 different positions in a small conference room (10.3mx5.8mx3.1m, RT=0.65s). The source, a loudspeaker Genelec 1030A, was always positioned in the same relation to the listening position. BRIRs were measured with an azimuth-resolution of 5° from 0°-360°. This data allows a psychoacoustical comparison of the room acoustical properties at different positions in the room.为探究房间声学感知随室内位置的变化规律，本研究采用KEMAR人头躯干模拟器（KEMAR head-and-torso-simulator）开展测量实验。将该仿真人头置于一间小型会议室的5个不同测点位置，该会议室尺寸为10.3m×5.8m×3.1m，混响时间（RT）为0.65s。声源采用Genelec 1030A型扬声器，其与听音位置始终保持固定的相对位置关系。本实验以5°的方位角分辨率，在0°至360°全角度范围内测量了双耳房间冲激响应（BRIR）。该数据集可实现对室内不同位置房间声学特性的心理声学层面对比分析。
