Paper about a local time stepping approach of the Discontinuous Galerkin time-domain method for room acoustics

Paper alert! Applying the Discontinuous Galerkin time-domain methods to room acoustics is time consuming if the mesh needs local refinement for geometrical reasons. In this JASA paper, a discontinuous time stepping approach is successfully presented, implying a release of the high computational constraint for meshes with strong local refinements. A next step in wave-based room…

Quantification of impact sound of lightweight wooden floors via heeldrops

Find out about our latest Acta Acustica paper! We experimentally explored the use of a heel drop as an impact source to quantify the impact sound performance of lightweight wooden floors. A impact force plate was used for this purpose. At low frequencies, the measurement quality using the help drop is higher compared to an…

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…

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…

New paper on wind effects on sound propagation from road traffic

The journal of the European Acoustics Association (EAA), Acta Acustica United with Acoustics, has just accepted the paper titled: "Numerical investigation of the effect of crosswind on sound propagation outdoors", by Maarten Hornikx and Timothy van Renterghem. In the paper, we show that the effect of wind on noise propagation from a line source (like…
