Semi-implicit characteristic-based boundary treatment for acoustics in low Mach number flows Universiteit Gent
Perceptual aspects of reproduced sound in car cabin acoustics KU Leuven
An experiment was conducted to determine the perceptual effects of car cabin acoustics on the reproduced sound field. In-car measurements were conducted whilst the cabin's interior was physically modified. The captured sound fields were recreated in the laboratory using a three-dimensional loudspeaker array. A panel of expert assessors followed a rapid sensory analysis protocol, the flash profile, to perceptually characterize and evaluate 12 ...

Imaging multiple defects in solids by means of selective source reduction and time reversed acoustics KU Leuven
Time reversal techniques are routinely used to identify sources of energy and/or scattering in medical applications, seismology and linear acoustics NDT. Inherent limitations of the traditional time reversal process in the case of multiple sources or scatterers make it difficult to distinguish the scattering sources individually. The Selective Source Reduction (SSR) method employs a subtraction technique to selectively suppress in amplitude (and ...
Speaker-Oriented Classroom Acoustics Design Guidelines in the Context of Current Regulations in European Countries KU Leuven
© S. Hirzel Verlag • EAA. Most European countries have regulatory requirements or guidelines for reverberation time in classrooms which have the goal of enhancing speech intelligibility and reducing noise levels in schools. At the same time, school teachers suffer frequently from voice problems due to high vocal load experienced at work. With the aim of improving working conditions for teachers, this article presents guidelines for classroom ...
Interactive Perceptual Evaluation of Auralized Acoustics in Rehearsal Spaces for Vocal Music KU Leuven
Acoustics of naturally ventilated double transparent facades KU Leuven
© 2017 Acoustical Society of America. This publication presents results of research on naturally ventilated Double Transparent Facades (DTF). The influence of the structural design of DTFs on the airborne sound insulation was investigated. For this purpose, 9 DTFs were measured in situ and 9 Double Transparent Façade Elements (DTF) were measured in a laboratory setting. The influence of the cavity thickness, the parallelism of the constitution ...
Phased Geometrical Acoustics using Low / High Frequency Reflection Coefficients with Applications to Absorption Measurements KU Leuven
The prediction of sound and noise in everyday environments is of utmost importance for comfort as well as for personal health. Although measurements give invaluable information about the behavior of existing environments, designers and engineers are also in need of predictive models that are both accurate and efficient. These simulations provide detailed analysis before construction or prior to renovations and thus yield a huge return on ...
Reverberation time and audibility in phased geometrical acoustics using plane or spherical wave reflection coefficients KU Leuven
Room acoustics parameters are typically predicted using some form of geometrical acoustics for large rooms. For smaller rooms, phased geometrical acoustics improves results for lower frequencies. The use of a spherical wave reflection coefficient improves the results further, yet the exact impact on room acoustics parameters is not fully known. This work predicts the reverberation time in medium-sized rooms (27 m3 < V < 300 m3) using ...
