Event Description 

In Vol 6 on Fluid Mechanics Landau/Lifschitz discuss the problem of acoustic propagation through a liquid filled with its vapor bubbles and showed that such a medium is very dissipative. Experimentally this was not seen. We argue that Landau/Lifschitz were wrong in neglecting the finite time needed for the condensation to take place. A new theory with this taken into account is in agreement with experiments.
