Below is a list of errata and additional notes for the content published. The authors would like to apologize for any inconvenience caused. 1. The surface impedance for random incidence angle should be corrected in Fig. 1. The updated figure is given below. [Formula presneted] Fig. 1. Surface impedance [Formula presneted] as a function of absorption coefficient [Formula presneted] for different incidence angles.2. It should be noted that [Formula presneted] is assumed in Eq. (25), which is true for all the materials used in the present paper.3. It should be noted that the source scaling for the FDTD simulations depends on the solver implementation. For the 3D standard rectilinear (SRL) scheme and the chosen FDTD solver used in the present paper, the scaling factor was computed as in Ref. [29] [Formula presneted] where c is the speed of sound, T is the time step, X is the spatial step size, and [Formula presneted] is the Courant number at the stability limit of the SRL scheme.4. The correction of surface impedance calculation leads to small deviations in the calculation of cases (d) and (e). The correct plots of (d) and (e) in Fig. 7 are given as follows and should replace the original ones. [Figure presneted] 5. The correction of surface impedance calculation leads to small deviations in the Table 1. Cases (d) and (e) are re-simulated as they are directly compared to the measurement data. The room acoustic parameters of cases (d) and (e) in Table 1 are updated and shown as below. Cases (a), (b), and (c) are not re-simulated because their focus has been on the comparisons of the two numerical solvers using the same material input. [Table presneted]
