Fig 3. Effects of tinnitus induction following SS on P1 and P4 ABR peak latencies.

(A) SS significantly increased P1 latencies as a function of stimulus intensity for all test frequencies except 36 kHz. Note that latencies converge to control values at higher intensities. (B) SS significantly affected P4 latencies in a complex manner for all test frequencies except 6 and 36 kHz. SS decreased the latency for P4 at higher intensities, but not at lower intensities. This effect on P4 was also seen in the GIN testing. (+ = significance by Sidak’s multiple comparisons method).
