The aim of this project is to maintain the experimental facilities in our institute's laboratory.

The lab consists of four testing places:

  • GREEN and BLUE: Two sound-booths (IAC-1202A) are used for audio recording and psychoacoustic testing performed with headphones. Each of the booths is controlled from outside by a computer. Two bidirectional audio channels with sampling rates up to 192 kHz are available.
  • RED: A visually-separated corner can be used for experiments with cochlear implant listeners. A computer controls the experimental procedure using a bilateral, direct-electric stimulation.
  • YELLOW: A semi-anechoic room, with a size of 6 x 6 x 3 m, can be used for acoustic tests and measurements in a nearly-free field. As many as 24 bidirectional audio channels, virtual environments generated by a head mounted display, and audio and video surveillance are available for projects like HRTF measurement, localization tests or acoustic holography.

The rooms are not only used for measurements and experiments, also the Acoustics Phonetics group is doing speech recordings for dialect research and speaker identification, for example for survey reports. The facilities are also used to detect psychoacoustical validations.

During the breaks in experiments, the subjects can use an Internet terminal or relax on a couch while sipping hot coffee...
