From: The impact of classroom soundfield systems on reading fluency in normal-hearing students
The relationship between participant non-verbal intelligence, as measured using the TONI-4, and the effect of SFA on reading fluency development, as measured using the Soundfield Effect score. The blue dots display individual data points, and the orange line depicts the best-fit linear regression. 95% CI for Pearson Correlation.
