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…

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…
