“…35 However, information on the far-field noise propagation was not presented in the study of Yu et al 22 Whereas with Tosh et al 29 , despite a good overall agreement with the experiment on the far-field noise predicted by a direct calculation, deviation of ~ 6-9 dB was observed in the mid-frequency ranges between (300 -700 Hz) among the microphone placed around the mirror, and the distant microphone was ignored. However, considering the large number of cells used in the cases mentioned above, the feasibility of extending it to realistic cases with a mirror integrated on a vehicle with the requirements proposed by Tosh et al 29 may be challenging.…”

“…For the far-field noise predictions, methods such as Ffowcs Williams-Hawkings (FW-H), Acoustic Perturbation Equations (APE), Lighthill's analogies and Direct Noise Computation (DNC) are commonly used for predicting and mitigating the induced noise from side-view mirrors. [29][30][31][32][33] Lokhande et al 34 used the LES approach with the FW-H analogy and DNC method for evaluating acoustic and compared the numerical prediction against the experimental by Siegert et al 13 The hydrodynamic pressure fluctuations were resolved accurately up to 700 Hz with a maximum deviation of 5-10 dB, and also SPL reported was in reasonable agreement with experiments at high frequencies against the experimental results of Siegert et al 13 Rung et al 14 observed a similar deviation in the SPL level predicted by DES with the FW-H analogy. The authors point out that the deviations in the studies mentioned above were attributed to the low-resolution of the grid in the wake and larger time steps used.…”
