TABLE III.
Average SNRs at threshold as a function of frequency for the NH and HI groups, as well as, individual SNRs for participants with sloping hearing loss. Bolded values with asterisks at 6000 Hz represent HI subjects whose quiet thresholds were not shifted by the presence of the masking noise
