Hi,

For acoustic simulations, you can use Computational Aeroacoustics (CAA) with a high-end, scale-resolving turbulence model like SBES, or you can decouple acoustics from flow dynamics using the Lighthill acoustic analogy (Fowcs Williams Hawkings)

You can check previous forum discussion: ANSYS FLUENT air velocity inlet inside enclosure

You can also check fluent user's guide: 22.2. Using the Ffowcs Williams and Hawkings Acoustics Model (ansys.com)
