... simulations

In order to see how much this peak in relative pressure amplitude was influenced by initial relative amplitude to background values, we repeated the simulation corresponding to model D05 with the same initial relative amplitude as model A05 (i.e., three orders of magnitude larger). Results show that there is not a significant difference in the peak values of the pressure and that the evolution is basically the same as the one of the original model.
