Figure 2. Similarity between electrically and acoustically evoked BM vibrations.

Figure 2

(a and d) For either acoustically or electrically evoked responses at a given stimulus level, the BM vibration magnitude increased with frequency and reached its maximum at 12.4 kHz at location A (panel a) and 15 kHz at location B (panel d). The pattern of the magnitude-frequency curves for low-level tones (blue lines) is similar to those evoked by currents (red lines). BM responses at 80 and 90 dB SPL showed the shifted broad peak and compressive growth. (b and e) Phase progressively decreased with frequency. (c and f) Phase lag of acoustically evoked BM vibrations referred to the stapes was similar to that of electrically evoked responses.
