Acoustic characterization of Hofstadter butterfly with resonant scatterers
Olivier Richoux, Vincent Pagneux
We are interested in the experimental characterization of the Hofstadter butterfly by means of acoustical waves. The transmission of an acoustic pulse through an array of 60 variab…
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…
Laser Doppler Velocimetry for Joint Measurements of Acoustic and Mean Flow Velocities : LMS-based Algorithm and CRB Calculation
Laurent Simon, Olivier Richoux, Anne Degroot +1
This paper presents a least mean square (LMS) algorithm for the joint estimation of acoustic and mean flow velocities from laser doppler velocimetry (LDV) measurements. The usual a…
Modelling the pressure field in the vicinity of a microphone membrane using PIV
Olivier Richoux, Anne Degroot, Bruno Gazengel +2
A new approach for for estimating the acoustic pressure in the near field of a microphone based on non-intrusive direct measurement of acoustic particle velocity is proposed. This…
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…
Analytical study of the propagation of acoustic waves in a 1D weakly disordered lattice
Olivier Richoux, E. Morand, L. Simon
This paper presents an analytical approach of the propagation of an acoustic wave through a normally distributed disordered lattice made up of Helmholtz resonators connected to a c…
