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.

  • 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.
  • equiment for speech recordings for speaker identicication


Vertical circular array of 22 loudspeakers generates acoustic signals from almost every direction. The listener is placed on a computer controlled swivel chair.
