TABLE III.
Individual and average slopes (top) and corresponding goodness of fit (bottom) for each listening condition. Only ipsilateral (Ipsi) and bilateral (Bi) precursor conditions were considered. The units of the slope are dB/dB, whereby a positive slope indicates that an increase in the precursor level (denominator) leads to an increase in the signal threshold (numerator).
