Personal profile


"Scientific research is craftsmanship"

Research profile

Maarten Hornikx is a Full Professor Building Acoustics, Vice-Dean of the Department of the Built Environment, and he leads the Building Acoustics Chair of Unit Building Physics and Services (BPS). Hornikx’ research area is modeling sound propagation in the built environment and his research interests are:

  1. Development of efficient numerical methodologies for sound propagation with the built environment as application, that is urban sound propagation, vibro-acoustics and room acoustics;
  2. Application of numerical models to investigate propagation effects as the role of vegetation on sound propagation outdoors and indoors, the influence of meteorological effects on sound propagation;
  3. Auralization from wave-based methods and hybrid wave-based/geometrical acoustics techniques;
  4. Auralization for human echolocation; Publishing open source software from developed methods

Academic background

Maarten Hornikx holds an MSc from TU/e (2004) and a PhD in Applied Acoustics from Chalmers University of Technology (2009). He was appointed as Assistant Professor at TU/e in 2012 and Associate Professor in 2017. During his studies, Maarten collaborated with TNO (2002) and the University of Mississippi (2007). From 2009 to 2011, he worked as a post-doc at KU Leuven in Belgium in the field of aeroacoustics. He was appointed as a senior researcher at Chalmers (2011-2013), focusing on modeling urban sound propagation in the EU funded projects Hosanna and QSIDE. Hornikx has spend a sabbatical period at Aalto University and Stockholm University (2018).

Maarten has published 41 peer reviewed journal papers and contributed to 55 conference papers on international acoustical conferences and meetings. He is associate editor of Acta Acustica united with Acoustics, and editorial board member of Building and Environment. He has been awarded two individual Marie-Curie fellowships: an ITN post-doc grant (2009) and a Career Integration Grant (2012). He is currently PI of an TTW OTP project (tools to tackle environmental health problems) and coordinates the H2020 ITN project Acoutect (2017-2020). Hornikx collaborates closely with several industry partners in the area of virtual acoustics and sound absorbing materials.
