We report experimental results about the 3D structure of shock waves on nonlinear acoustical vortices (AV). We will investigate classical shock waves (in the direction of propagation) and the azimuthal ones (in the transverse plane). At last, both quasi-monochromatic and transient regimes will be considered.
