TABLE V.
Methodological details for assessing gain reduction from previous studies. Data are shown in Fig. 8. The studies are ordered by precursor laterality (Contra, contralateral; Ipsi, ipsilateral) and masking type. FDMC, fixed-duration masking curve; FM, forward masking; SL, sensation level; SM, simultaneous masking; BBN, broadband noise; NBN, narrowband noise; PTC, psychophysical tuning curve; TMC, temporal masking curve; ERB, equivalent rectangular bandwidth.
