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:

The dataset is the basis of the analyses of the following papers:
