It is easily shown in the schematic that the global bubble position changes as the acceleration changes, which also leads to a change in the acoustic forcing.

Assume that the bubble experiences some total acceleration a(t).  The balance of body forces is:

1. a(t) will cause the levitation position of bubble to change:
   new position  Þ  new P_a
   solve RP @ new P_a  Þ  new R_o (diffusive stability: PaØ RoØ)
   solve RP @ new R_o  Þ  new R_max

2. a(t) will cause the ambient pressure to change:

The hydrostatic term is usually ignored because it only changes about 1%.  However things are different when a change in acceleration is considered.
solve RP @ new P_o  Þ new R_o and R_max at new P_a
Þ change in SL intensity DI_SL
