Room Impulse Response Dataset - ACT, DTU Electro (019)

Dataset of Room Impulse Responses measured at the Acoustic Technology group, DTU Elektro.
The dataset consists of measurements of the acoustic impulse response inside a classroom for two loudspeaker positions. The dataset includes a total of 1386 measured impulse responses for each of the speaker positions, where the microphone was automatically positioned using a scanning robotic arm.


The impulse responses were acquired inside a classroom belonging to the Acoustic Technology group facilities at DTU Elektro (Ørsteds Plads, building 352, 2800 Kongens Lyngby, Denmark). In the dataset this room is called 019. Room 019 is a furnished classroom, acoustically treated with absorptive material on the ceiling and distributed on two of the room walls. The furniture consists of tables, chairs and blackboards. The shape is not completely shoebox-type. There is a shelf below the windows that covers the radiators.

A detailed description of the measurement setup can be found in the Readme.html file, as well as in the publication E. Fernandez-Grande, D. Caviedes-Nozal, M. Hahmann, X. Karakonstantis and S. A. Verburg, "Reconstruction of room impulse responses over extended domains for navigable sound field reproduction," 2021 Immersive and 3D Audio: from Architecture to Automotive (I3DA), Bologna, Italy, 2021, pp. 1-8.
