I have modelled water as Acoustic element. A cylindrical acoustic wave at 1MHz is created in the medium. When i monitored the acoustic pressure (POR) at another node inside medium I get field at 800kHz. Why this change in frequency is observed? The reduction in amplitude is quite expected due to attenuation, buut not frequency
