Biography:
  Sebastian Arndt is a researcher at the Quality and Usability Lab of the Telekom Innovation Laboratories, TU Berlin. He studied Computer Science at Technische Universität Berlin and received his diploma in 2010. He received his doctoral degree (Dr.-Ing.) in 2015 with the thesis title 'Neural Correlates of Quality During Perception of Audiovisual Stimuli'. His current research focus is on physiological changes during the perception of audiovisual quality. 2012 he was a visiting researcher at MuSAE Lab (Montreal, Canada) in order to work on multimodal neural correlates for synthesized speech.

Zusammenfassung Common methods to determine the quality of media rely on conscious ratings of a subject's opinion about the quality of presented stimuli. While such methods provide a reliable and valid means of determining quality, they provide little insight into the physiological processes preceding the quality judgment, which, however, may affect the subjective behavior, e.g., in terms of alertness or media usage duration. In this paper we used a non-intrusive physiological method, electroencephalography, to assess the cognitive state of subjects related to the quality of auditory speech stimuli. We show that users listening to degraded audio rated the quality lower in comparison to an undisturbed stimulus as expected and, in addition, got more fatigued during the 20 minute presentation. Indicators of the increased fatigue were Theta and Alpha frequencies of the electroencephalogram data. The results show that the perception of degraded media has long-term influences on physiological processes at the time scale of minutes which may immediately influence customer behavior.
