The ARI lab consists of four testing places:
The rooms are not only used for measurements and experiments, but also for speech recordings, speaker identification and survey reports.
During the breaks in experiments, the subjects can use an internet terminal or relax on a couch while sipping hot coffee...
A semi-anechoic room (6.2m × 5.5m × 2.96m) is available for acoustic measurements. Also psychoacoustic experiments like sound-localization experiments can be performed.
The room is equipped with:
a 22-loudspeaker array for HRTF measurement;
64-microphone array for various recording approaches (beam forming, near-field holography);
a virtual-environment setup for tests with subjects in a virtual visual and acoustic environment controlled with a head tracker in real time.
|22 loudspeakers in the median plane generate acoustic signals from almost every direction. The listener is placed on a computer controlled swivel chair.|
