• Random propagation times are able to model waves attenuation and velocity.
• It is true for electromagnetic waves (light, radar, guided propagation) and also for acoustics and ultrasounds (acoustics for high frequencies).
• About the latter, it can be shown that stable probability laws are well-fitted for frequencies up to dozens of megahertz in numerous cases.
• Nowadays, medical applications are performed using propagation through perfluorocarbon (PFC).
• Experiments were done to measure attenuations and phase changes.
• Using these results, this paper addresses the question to know if stable probability laws can be used to characterize the propagation of ultrasounds through PFC liquids.
