Yes, I think that wall-modelled LES approach would be ok for this purpose.
Coming back to the question about compressibility. In literature I found the following statement:
The latttice-Boltzmann method is well-suited for the aeroacoustics applications since it is a Lagrangian
method based on a stream-and-collide scheme, and is inherently unsteady and compressible and thus physically deals with sound pressure waves. (https://arc.aiaa.org/doi/10.2514/6.2016-2969)
How does this relate to what you wrote about the possibility of performing analyzes as incompressible?
