Biography
As of May 2016, Jens Ahrens is with Chalmers University of Technology [2].
Jens Ahrens received a Diploma in Electrical
Engineering/Sound Engineering (equivalent to Master of Science) from
Graz University of Technology and University of Music and Dramatic
Arts Graz, Austria, in 2005 and the Doctoral Degree (Dr.-Ing.) from
University of Technology Berlin, Germany, in 2010 both with
distinction. From 2006 to 2011 he was member of the Audio Technology
Group at the Quality and Usability Lab where he worked on the topic of
sound field synthesis. From 2011 to 2013 he was a Postdoctoral
Researcher at Microsoft Research in Redmond, Washington, USA. In the
fall/winter terms 2015/16, he was Visiting Scholar at Stanford
University. He received the literature award 2013 of the Information
Technology Society (ITG at VDE). Find more information here [3].

| Zusammenfassung | Massive multi-channel auralization approaches like Wave Field Synthesis and Higher Order Ambisonics experienced a pronounced hype in the late 2000s during which the primary research goal was maximizing the physical accuracy of the synthetic sound fields that they create. The hype eventually faded as the achievable advancements turned out to be limited due to fundamental restrictions. Though, activities are still being pursued in the domain with the focus shifted towards perception of synthetic sound fields. This talk gives an overview over current activities, which aim at understanding localization, timbre, and spatial impression in general. The results show that localization performance in synthetic sound fields is close to the performance in real sound fields. Timbre and spatial impression exhibit impairments that are directly linked to the physical limitations of the employed systems. Promising options for improvements regarding the synthesis of artificial reverberation are discussed. |
