The interleaved ramp stimulus design yields greater wave 1 amplitudes than the conventional stimulus design, regardless of presentation rate (n = 17 ears from gerbil, 8 ears from mouse). a Comparison of ABR waveforms (ensemble average across all ears) acquired using the interleaved and conventional stimulus designs. Data shown are in response to 40/s 22.6-kHz, 80-dB SPL tone pips in mouse. Numbers indicate wave. b Average ABR thresholds for each frequency, presentation rate, and stimulus design. c Average wave 1 amplitudes vs. stimulus level for 22.6-kHz tones in mouse. d Average wave 1 amplitudes at 80 dB SPL. e Average wave 1 latencies vs. stimulus level for 22.6-kHz tones in mouse. f Average wave 1 latencies at 80 dB SPL. Shaded area and error bars in all panels indicate ±SEM.
