   Hi everyone,

   if you had the exact same system consisting of a transducer A in a medium B, what kind of differences are to be expected if the pressure of the system increased? For example let's say the transducer A has a source strength of 50kPa, and the medium B is at ambient pressure. You then get a pressure field C.

   Now, what if the medium B is at double the pressure and the source strength of the transducer remains the same, what happens to the pressure field C?

   Could this be simulated using KWave?

   Cheers,
   -A

   Hi AndresMM,

   There is no direct way in k-Wave to specify the ambient pressure. However, this only affects the wave field via the sound speed (and potentially other material parameters). For example, in air, the sound speed has a very weak dependence on the atmospheric pressure. If you have details of how the material properties change with the ambient pressure, then you could use these in the simulation.

   Hope that helps,

   Brad.
