Figure 1. (A) N1 latency, difference score (post-test – pre-test) at Cz in the active condition of the syllable-in-noise task in choir and control groups, across SNR conditions. (B) ERPs recorded at Cz during active condition of the syllable-in-noise task in the choir and control groups at pre and post-test for each noise condition. (C) Topographic headplots for N1 during active condition of the syllable-in-noise task in the choir and control groups at pre and post-test for 0dB and Silent conditions.
