Simulating SPL Frequency Response of an enclosure using Ansys

[LAJP]

Hi,

I have been using Ansys' harmonic acoustics module recently to simulate and validate my enclosure designs. I have attached pictures of my CAD model and the corresponding frequency response. I've noticed that the response fluctuates a lot as you move from low to high frequencies. Furthermore the SPL is lower at higher frequencies.

Has anyone got any ideas on how I redesign the enclosure to achieve a smoother more uniform frequency response?

Thanks in advance
