Listening Matters in Building and Room Acoustics KU Leuven
Listening tests play a crucial role in research and in the development of applications in room and building acoustics. Complementary to classical setups in which sound is presented to listeners via loudspeakers, advanced binaural auralisation tools nowadays allow for realistically presenting acoustic scenarios to listeners. In this work, we report on research results obtained by listening using both approaches, and the comparison between them. ...

Influence of panel fastening on the acoustic performance of light-weight building elements: study by sound transmission and laser scanning vibrometry KU Leuven
Structural details and workmanship can cause considerable differences in sound insulation properties of timber frame partitions. In this study, the influence of panel fastening is investigated experimentally by means of standardized sound reduction index measurements, supported by detailed scanning laser Doppler vibrometry. In particular the effect of the number of screws used to fasten the panels to the studs, and the tightness of the screws, ...

Application of the wave based prediction technique to building acoustical problems KU Leuven
The Wave Based Method (WBM) is used to predict the airborne and structure-borne sound insulation of building structures. In building acoustics, the frequency range of interest is 50-5000 Hz. Prediction models in building acoustics often assume infinite structures (like the transfer matrix method) or diffuse sound fields (statistical energy methods). These models cannot explain the inter-laboratory differences typically encountered in the lower ...
Numerical investigation of the repeatability and reproducibility in building acoustical measurements KU Leuven
An extensive parametric study has been carried out with a wave based model to numerically investigate the fundamental repeatability and reproducibility in building acoustical measurements. In this paper, the sound transmission loss variability of single and double partitions is discussed. To achieve the desired repeatability, a reliable measurement procedure is important. Therefore, the influence of the number of microphone positions and the ...
