Box plots indicate the range of localization performance for each participant group. The box depicts the interquartile range transected by the median; tails represent the 10th to 90th percentiles, and outliers are indicated with open circles or a plus symbol. Brackets and asterisks denote significant differences, *p< 0.05, ***p< 0.001. UHL indicates unilateral hearing loss; NH, normal hearing; RMS, root mean square. Panel A are results from the total loudspeaker array; Panel B from loudspeakers ipsilateral to the open ear (or right ear of NH-bilateral participants); Panel C from loudspeakers contralateral to the open ear (or left ear of NH-bilateral participants).
