International audience; This article reports an experimental study of the vibrations induced by air leaks in realistic conditions reproducing a leak test of a containment building, such as those routinely conducted to probe the safety of nuclear powe

A nonlinear acoustic method to assess the damage level of a complex medium is discussed herein. Thanks to the highly nonlinear elastic signatures of cracks or, more generally, internal solid contacts, this method is able to distinguish between contri

In this talk, we report results on the nonlinear interactions of ultrasonic coda waves with lower pump waves, in reverberating or multiple scattering mesoscopic solid media. Using the method of coda wave interferometry (CWI), we analyze the effect of
