Mean DPOAE decrements in dB as a function of L3 in dB SPL when f2=4000 Hz and L2=30 dB SL. Error bars represent ±1 s.d. Suppressor frequency is indicated within each panel. Closed symbols represent the transformed data to which a linear regression, represented by the solid line, was fit. The short vertical dashed lines in each panel are drawn at a decrement of 3 dB, which was used as suppression threshold for the construction of STCs.
