The effects of multiple arrivals on the intelligibility of speech produced by live-sound reinforcement systems are examined. Investigated variables include the delay time between arrivals from multiple loudspeakers within an array and the geometry and type of array. Subjective testing, using captured binaural recordings of the Modified Rhyme Test under various treatment conditions, was carried out to determine the first- and second-order effects of the two experimental variables. Results indicate that different interaction effects exist for different amounts of delay offset.
