A Binaural speech perception in noise scores for children with NF1 [5]. Shown are speech reception thresholds for the Listening in Spatialized Noise test (DV90 condition). The shaded area represents the mean ± 2SD performance range for normally developing children. Unfilled data points are findings for participants recruited to the intervention study. B Open-set speech perception in noise (0 dB SNR) scores as a function of participant age. Unfilled data points show the phoneme score for each individual in the inactive device condition and the filled points are for the active device condition. The shaded area represents the (no device) 95% performance range for children with no auditory processing deficits based on published normative findings [8, 9, 13]. C Mean LIFE-R rating scores for intervention study participants (open data points) and classroom-teachers (filled data points) at each of the three data collection points. Error bars represent ± 1 standard error
