Our lab is located at two floors, in the basement and in the second floor of the building. The chamber are named by colors. 

Basement:

The facilities in the basement consists of five testing and measurement stations:

• GREEN and BLUE (ISF Grün, ISF Blau): Two sound booths (IAC-1202A) can be used for audio recording as well as for phonetic, psycholinguistic, 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. Booth booths can also be equipped with an ultrasound system for tongue imaging (Micro Speech Research Ultrasound System, Articulate Instruments Ltd). The GREEN booth is further equipped with a 128-channel EEG system (actiCHamp, Brain Products) and an eyetracking system (Eyelink 1000 plus, SR Research) with a sampling rate of up to 2000 Hz.
• RED (ISF Rot): A visually-separated booth without acoustic treatment can be used for experiments with cochlear-implant listeners. The RED booth is equipped with a computer controlling the experimental procedure for bilateral direct-electric stimulation.
• YELLOW (ISF Gelb): A semi-anechoic room, with a size of 6 x 6 x 3 m³ can be used for acoustic tests and measurements in semi-anechoic conditions. 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. 
• PURPLE (ISF Lila): A semi-anechoic loudspeaker array studio with 91 loudspeakers and 2 subwoofers on a size of 3 x 3 m². The system can be controlled from outside in the control room and is equipped with a 192-channels audio setup, 96-channel amplifiers, headphones, VR setup, and a computer.

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 in the lounge while sipping hot coffee...
