How to obtain the a0 (Inward acceleration) of a transducer in water?

Hi all, I am simulating an accoustic chamber using water. In the pressure accoustics node, Comsol requests an a0 value or inward accelaration. I know this is an experimental value, but is there any source where I can get plausible a0 value for transducers vibrating in water? at least which order of magnitude could it be?
Best regards,

Karina,
this depends on the type of transducer and may vary by orders of magnitude. In the first place it does not really matter, because pressure acoustics is linear and it is thus only a scaling factor. If you know e.g. input power to the specific transducer you should be able to make an estimate based on the transducer geometry.
