Need help in output acoustic pressure in air domain

Hello,everyone
I used Pressure acoustic, frequency domain and electromechanics Physics, 2D-axisymmetric to simulate a vibration membrane to get the output pressure in the water domain. The result is good. But when I changed the water domain into air domain, the shape of the output pressure line is very strange, the line is very flat at the beginning, but change very sharp unexpected.
The x-coordinate is frequency. I don't know why.could anyone can give me some advises please? Thank you in advanced!

Could you post figures displaying the output as a function of frequency? Or post the model file?
