  In the present work, an attempt is made to map the sensitivity of the
existing zero pressure gradient (ZPG) turbulent boundary layer (TBL)
wall-pressure spectrum models with different TBL parameters, and eventually,
with different Reynolds Averaged Navier Stokes (RANS) turbulence models,
simulated in OpenFOAM and ANSYS Fluent solvers. This study will help future
researchers to choose a particular RANS turbulence model vis-\`a-vis a
particular wall-spectrum model in order to obtain a reasonably accurate wind
tunnel result predicting capability. First, the best-predicting pressure
spectrum models are selected by comparing them with wind tunnel test data.
Next, considering the experimental TBL parameters as benchmarks, errors in
RANS-produced data are estimated. Furthermore, wall-pressure spectra are
calculated following semi-empirical spectrum models using TBL parameter feed
obtained from experiments and computational fluid dynamics (CFD) simulations.
Finally, sensitivity mapping is performed between spectrum models and the RANS
models, with different normalized wall-normal distances (y+).
