Two separated tone pulses aid detection more than one, unaffected by intervening noise level

Evidence

First, thresholds were better for two tone pulses than for one. Second, the intervening noise had little effect on the detection threshold, regardless of whether it was incremented or not. Both pieces of evidence are compelling in support of the multiple looks model. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 1068
