The first of our data collection campaigns started in Oldenburg a few weeks ago. In measurement sessions of four hours each, subjects go through several conditions of different audiological complexity and movement requirements. Meanwhile, physiological data such as electroencephalography (EEG) and electrocardiography (ECG) as well as behavioural data regarding attention and listening fatigue are recorded. The multimodal data that is collected during this study will later be used to train the AI algorithms.
