Schematic illustration of the study design. The four conditions “+3 dB OFF,” “+3 dB ON,” “+8 dB OFF,” and “+8 dB ON” were tested with 20 trials each. For each condition, the trials were randomized with five consecutive trials with attended speaker being “male right (MR),” “male left (ML),” “female right (FR),” and “female left (FL).” The order of these subconditions was randomized between conditions and participants and were applied to avoid bias toward one of the speakers or spatial awareness.
