In the listening booth, headphone-based audio-visual listening tests are conducted, for example, the evaluate the sound quality of 3D audio scenes. With an area of 6 square meters, a high attenuation of airborne ambient noise of 45 dB and a low reverberation time of 0.3 s above 500 Hz, the booth is also suitable for experiments that require a particularly low-noise environment.
The smaller of the two TU-Studios has two playback systems for spatial audio applications. The loudspeaker dome with 21 tweeters and two subwoofers enables the creation of three-dimensional sound spaces with playback methods such as Ambisonics or Vector Base Amplitude Panning (VBAP). A wave field synthesis system (WFS) with 192 channels is available for precise localisation within a two-dimensional plane at head height. Both systems are controlled by dedicated software that was developed by the group and is currently undergoing further research.
The WellenFeld H 104 auditorium and event hall at the TU Berlin has the world's largest wave field synthesis (WFS) system. Around the entire hall with a capacity of about 640 seats, a band of more than 2700 loudspeakers at a distance of 10cm stretches at head height. These are controlled by a computer cluster with 832 audio channels.
The large TU-Studio provides space for diverse projects in the field of experimental electronic music and media arts. Music interaction systems and artificial intelligence applications in real-time audio environments are explored in collaboration with artists. The studio is equipped with 20 flexibly controllable speakers as well as a classical stereo monitoring system. A modular synthesizer, the SynLab Spree system, is also part of the permanent installation. Among others, the Electronic Orchestra Charlottenburg rehearses in the large studio.
