Fig. 7.

ABR wave latencies as a function of noise exposure. The top row shows ABR latencies generated by the 100 dB peSPL click and the bottom row those from the 80 dB peSPL click. The columns show the latencies of waves I, III and V. All values are baseline corrected so that all three latencies are distributed around zero to allow common axes to be used. The baselines for the 100 dB click were 1.84, 3.85 and 5.74 ms for waves I, III and V respectively. For the 80 dB condition they were 2.69, 4.46 and 6.41 ms. Regressions are again plotted for the three groups (all listeners, males and females) with Pearson correlation coefficients shown in the text (* = p < 0.05, ** = p < 0.01). The numbers in brackets are the numbers of participants who produced a measurable peak in each case (see Section 2.5.3).
