PhD vacancy on modelling for perception of noise from urban air mobility aircraft in urban environments

Picture for inspiration from businesswire.com The Royal Netherlands Aerospace Centre NLR offers a great opportunity together with the TU/e. Interested in urban air mobility and the perception of noise? This PhD position might be your opportunity! As the project is hosted by NLR, all information and application details can be found at their website. Background…

New approach to measure absorption of vegetated roofs

How much sound does a vegetated roof absorb? To answer that question an appropriate measurement method is needed. In our recently published Applied Acoustics paper by Chang Liu, Fotis Georgiou and Maarten Hornikx, the acoustic impedances of greens roofs were retrieved by fitting parameters of a surface impedance model by measurents on the roofs. It…

Residents of Groene Hart develop aircraft noise measurement network

Annette Pietersen, Guus Elkhuizen, Jan Leendert van den Heuvel and Maarten Hornikx are working together on a citizen measurement network Airplane noise Groene Hart. Source: nieuwkoper.nl The number of flights to and from Schiphol doubled between 1990 and 2018 to almost five hundred thousand a year. This growth has led to a significant increase in nuisance…

Auralization of a car pass-by using measured impulse responses

In our recent open-access paper in Applied Acoustics, we publish a method to auralize a pass-by of a car in a street based on measured impulse responses. Listening tests have assisted to discover the influence of the resolution of impulse response source positions on audible differences. First author is Fotis Georgiou, he obtained his PhD from…

New journal paper

The Applied Acoustics journal has just accepted our journal paper "Meteorological effects on the noise reducing performance of a low parallel wall structure". A low parallel wall structure along major roads can reduce road traffic noise substantially. In this work we address the performance of this structure when meteorological effects do influence its noise reduction.…

Ten questions paper

  My ten questions paper on computational urban acoustics is in press in the journal Building and Environment (it can be found here). The paper contains ten questions and answers related to the need for computational acoustics methods, the relevance of including various urban propagation effects in computational modelling, and to the preferable computational methods and…

New paper open openPSTD software

The Elsevier journal Computer Physics Communications, has accepted the paper titled: “openPSTD: the open source pseudospectral time-domain method for acoustic propagation”, by Maarten Hornikx, Thomas Krijnen and Louis van Harten. The paper presents the implementation of our open source software openPSTD (www.openPSTD.org) for accurate computation of sound propagation in the built environment. The software will be…
