Speech reception thresholds (SRTs) were measured at a central focus of attention and at 20 degrees, 40 degrees, and 60 degrees locations distant in azimuth. Measurements were taken with one target collocated with two maskers, or with maskers flanking the target by +/-20 degrees. For 80% of trials, the target was played from the attended location ("expected… CONTINUE READING
