Recorded speech PR measure vs. source location. The measured (temporally averaged) PR (18) of all microphone arrays (1–6) vs. the source position in the hall. The x-axis describes where the source is located relative to the arrays (near an array or between two adjacent arrays). The microphone arrays are located lengthwise along a hall of size 15×10×6 m, with a 3-m spacing between adjacent arrays
