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.</p> <p>Hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/ultrasonic-field-at-different-pressures#post-5620 Tue, 02 Aug 2016 07:48:34 +0000 AndresMM 5620@http://www.k-wave.org/forum/ <p>Hi everyone,</p> <p>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.</p> <p>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?</p> <p>Could this be simulated using KWave?</p> <p>Cheers,<br /> -A </p>
