Piotr Majdak

Acoustics Research Institute, Austrian Academy of Sciences (Austria)


Piotr Majdak, of the Acoustics Research Institute, Austrian Academy of Science, works on a better understanding of spatial hearing in humans. This involves research on the perceptual effect of the head-related transfer functions (HRTFs), their acoustic measurement and numeric calculation. It also includes spatial-hearing aspects in hearing-impaired population such as cochlear-implant users. His scientific work is also linked with the development of software such as the auditory modelling toolbox (AMT) and standards such as the spatially oriented format for acoustics (SOFA). He is a lecturer in the field of acoustics and audio engineering at various universities.

In SONICOM, first, Piotr Majdak will develop auditory models enabling other groups to estimate the impact of various measures on the spatial perception. Second, he will work on methods towards creating self-personalizing headphones. Third will be to create a SONICOM ecosystem, an open-source playground of software packages, experiment data, and machine-learning approaches, available to researchers interested in personalized spatial AR/VR systems.
