Acoustic Power Level Showing areas of 0dB in broadband noise model

      Hello. I have been trying to simulate broadband noise model acoustics for a certain 2D model and I happen to get these large spots where there is no sound power levels. This issue is only noticeable for acoustics and nothing else. My meshing is correct(afaik). I ran and re-ran simulations to fix this but even then it persists, please help me here I would really appreciate it!

      I notice two major areas of issue, one at the top where there is a large portion of no power, and one near the centreline where there is yet another area of no sound. Why has this happened? I would love to clear this up and fix it

      I have linked the images for the acoustics and the turbulence Kinetic energy, if anyone requires anything else from the simulation file I am happy to share it.

      Thank you

      This could be due to mesh sizes.. Would you please refine the mesh and check. Also its good if you explain your CFD set up.
