This PhD focuses on the sound insulation of building envelope components based on acoustic metamaterials, and fits in the framework of the ACTAREBUILD EU – DN – project. See project website:

This interdisciplinary research is hosted by KFB Acoustics, Wroclaw, Poland. Academic supervision will be provided by Prof. Elke Deckers (Mecha(tro)nic System Dynamics (LMSD), Diepenbeek Campus, Department of Mechanical Engineering) and Prof. Christ Glorieux (Laboratory of Acoustics in the Soft Matter and Biophysics Unit of the Department of Physics and Astronomy) at KU Leuven, Belgium, and Dr. Daniel Urban of the Faculty of Civil Engineering of the Slovak Technical University (STU) in Bratislava, Slovakia. The joint PhD degree will be awarded at KU Leuven and STU Bratislava.

Adaptation of building envelope components in the revitalization process of office buildings to dwelling opens several acoustic and thermal challenges, both for the indoor and outdoor environment. Sound insulation properties of building envelope components are crucial for a proper acoustic comfort indoors.

The noise present in urban areas is known to dramatically increase when so-called street canyons are formed by arrays of tall buildings, typically in financial districts with office buildings, which consequently affects the indoor environment. Considering acoustic metamaterials in building envelope components can be a feasible and effective solution to optimize the noise level, as these innovative systems introduce new physical phenomena that can be tuned in frequency in order to mitigate noise. Specific tonal components, such as e.g. tram squealing noise, can thus be effectively filtered. In this PhD project we will examine the impact of novel components integrating metamaterials for the reduction of urban noise in buildings. The main task of the student will be the design of the resonant inclusions, the optimisation of (1) the element size, (2) the number of elements and (3) their position on the building envelope components to reach the desired noise reducing effect. The optimisation will be validated using acoustic measurements on prototypes, supported by computer simulations.



  • A remuneration package in line with Marie Sklodowska Curie Doctoral Network regulations, which is competitive with industry standards in Belgium, a country with a high quality of life and excellent health care system.
  • The researcher allowances granted by Europe will cover all (employer’s and employee’s) taxes and contributions; the exact (net) salary will be confirmed upon appointment.
  • An opportunity to pursue a PhD in Science, in a stimulating and ambitious research environment, with 3 years funding within the ACTAREBUILD ITN project. This PhD will be performed in collaboration with KU Leuven (Belgium) and STU Bratislava (Slovakia) and the candidate will be awarded by a joint PhD degree.

  • KFB Acoustics offers research and consulting services in noise management, product development and environmental sector. For over a decade it has been solving complex noise and vibration problems and providing complete product development services to the world’s leading organizations across all industries. The company’s growth has led to the development of Acoustic Research and Innovation Centre – ARIC. Its infrastructure combines laboratories and numerous acoustical chambers that enable acoustic research in various fields. With a community of engineers and scientists, excellent laboratory equipment, and state-of-the-art measurement and analysis methods, ARIC may serve as a top class facility to commercial, educational and scientific applications. Along with the access to ARIC full infrastructure and specialized equipment and software, the candidate may count on the support of the team of experts. Moreover, KFB Acoustics has created a Scientific Advisory Board (SAB), which is composed of researchers and professors from all over the world. The members of SAB are recognized experts in different fields of acoustics, such as metamaterials, building acoustics or vehicle noise, among others, and serve the company with their expertise. In addition, since 2016, KFB Acoustics has been a member of the Acoustics Committee of the Polish Academy of Sciences. Also, the company is an owner of acoustics e-learning platform
  • Exchange visits with the academic partners at KU Leuven (Mecha(tro)nic System Dynamics (LMSD), Diepenbeek Campus, Department of Mechanical Engineering and Laboratory of Acoustics at the Department of Physics and Astronomy), in a vibrant environment in the hearth of Europe. Leuven is a town of approximately 100000 inhabitants, located close to Brussels (25km), and 20 minutes by train from Brussels International Airport. This strategic positioning and the strong presence of the university, international research centers, and industry, lead to a safe town with high quality of life, welcome to non-Dutch speaking people and with ample opportunities for social and sport activities. The mixture of cultures and research fields are some of the ingredients making the university of Leuven the most innovative university in Europe.
