The research results of the CRC are consolidated and integrated towards demonstrable output related to the overarching goals of the CRC. Four demonstrators are available:

• Demonstrator D1: Simulation Toolbox for speech perception, listening effort, audio quality and spatial perception
• Demonstrator D2: The acoustically transparent hearing device
• Demonstrator D3: The immersive hearing device
• Demonstrator D4: Virtual audiovisual scenes and sound field reproduction technology for hearing acoustics
