Figure 2. Effect of complete ischemia on DPOAE level in a gerbil ear (f2 = 8 kHz; f2/f1 = 1.20; 60 dB SPL primary intensities; ischemia started at t = 0 - vertical dotted line). DPOAE levels were sampled every 10 s. Thin horizontal lines: top, average initial DPOAE level; bottom: average noise floor.
