Characterization by a time-frequency method of classical waves propagation in one-dimensional lattice : effects of the dispersion and localized nonlinearities
Olivier Richoux, Claude Depollier, Jean Hardy
This paper presents an application of time-frequency methods to characterize the dispersion of acoustic waves travelling in a one-dimensional periodic or disordered lattice made up…
Effect of the open roof on low frequency acoustic propagation in street canyons
Olivier Richoux, Ayrault Christophe, Adrien Pelat +2
This paper presents an experimental, numerical and analytical study of the effect of open roof on acoustic propagation along a 3D urban canyon. The experimental study is led by mea…
Synthèse sonore de la clarinette avec modèle de résonateur à trous latéraux optimisé sur des impédances d'entrée d'une clarinette réelle
Fabrice Silva, Philippe Guillemain, Jean Kergomard +1
Sound synthesis can be developed using physics-based modelling of the musical instruments. These methods need the description of the various parts of sound production mechanism, in…
Validity of the one-dimensional limp model for porous materials
Olivier Doutres, Nicolas Dauchez, Jean-Michel Génevaux +1
A straightforward criterion to determine the limp model validity for porous materials is addressed here. The limp model is an "equivalent fluid" model which gives a better descript…
