Summary: This session analyzed the correlation between the binaural summation measured via acoustic reflex thresholds and the results of the masking level difference established for 500 Hz in 60 participants. The Pearson Correlation Analyses between the MLD values and the binaural summation revealed a significant (r= 0.277; p = 0.032) correlation when the probe stimulus was presented to the right ear and the reflex evoking clicks were presented to the left ear. Although the correlation is significant, the effect size is small, suggesting that each measure may provide information about both similar and different aspects of binaural processing and can be included in a battery of auditory processing disorders (APD) tests.
