This work introduces Directional Coherence Loss Coefficients (DCLCs) to quantify the angular distribution of sound field coherence loss, arising from localized scattering distributions within an enclosure, from a receiver's perspective. These DCLCs can be applied in hybrid room acoustic models, where the coherent component is computed from the empty-room case and the incoherent component is simulated using a stochastic approach, with proportions decided by DCLCs.

Check "DCLC_HybridModel.mlx" for the code to extract DCLCs and a hybrid model to reconstruct the sound field.
