Academic Background

Katharina Pollack studied Electrical Engineering Audio Engineering in Graz, both at Technical University and the University of Music and Performing Arts and finished her Master's degree in November 2019. During her studies, she worked in various companies and institutes in the fields of signal processing, speech communication, electronical engineering and acoustic engineering.

After an internship at the Acoustics Research Institute, she continues her work on pinna modelling in a PhD programme within the softpinna project.

Current Research

Head-related transfer functions (HRTFs) represent the influence of the anthropometric properties on the incoming sound field. Not only are the interaural time differences (ITDs) and interaural level difference (ILDs) important for the localization ability of humans but also the shape of the outer ear - the pinna - is essential to this process. The state-of-the-art measurement process of HRTFs is well studied and the numeric calculation of the measurement (Ziegelwanger et al., 2015) was a milestone in this field, enabling perceptual valid HRTFs to be processed from 3D Models of the head and pinnae. However, this process relies heavily on high-quality 3D models, with a resolution of 1 mm and the acquisition of such a 3D model has been examined thoroughly within the LocaPhoto project. Katharina Pollack's current research focuses on the investigation in the influence of pinna changes in the HRTFs and parametric pinna modelling. This shall conclude the missing link between the properties of HRTFs and the virtual representation of complex biological structures such as the pinna.
