Fig. 3

Plan view of the M1 microphone configuration and the LS-SAL loudspeaker configuration. A description of the microphone and loudspeaker labels is given in Table 2. The radial grid spacing of the polar plot is 0.25 m. The DH is placed at a height of approximately 1.3 m ear level from the floor and all XMs are placed at a height approximately 1 m from the floor. The trapezoidal shape is used to represent the M1 microphone configuration in the floor plans of Fig. 6. For extracting the coordinates of the microphone and loudspeaker positions, the MATLAB or Python scripts discussed in Section 6.2 should be used
