(A) Recorded EABRs evoked by stimulation of the auditory neurons using electrical signals from the sixth channel of the ABM with pure-tone acoustic stimuli of 95-dB SPL at 4.43 kHz, which is the corresponding resonance frequency. Stimulus onset was at time 0. Waves I, II and III are indicated in the EABR recordings. (B) Recording of EABRs with acoustic stimuli from 70–95-dB SPL at 4.43 kHz to the same channel as in (A). (C) The magnitude of wave II as a function of the input sound pressure. (D) Recordings of EABRs with acoustic stimuli from 80 to 95 dB SPL at the sixth channel of the ABM with pure-tone acoustic stimuli at 6.85 kHz, which is an off-resonance frequency of the cantilever. (E) Recordings of EABRs using the fourth channel of the ABM with pure-tone acoustic stimuli at 6.85 kHz, which is the resonance frequency of the corresponding cantilever. (F) Recordings of EABRs using the fourth channel of the ABM with pure-tone acoustic stimuli at 4.43 kHz, which is an off-resonance frequency of the cantilever.
