ABR data acquired using the interleaved stimulus design in other species. a ABR waveforms from a single ferret ear using a 10-frequency (2 to 45.2 kHz), 15-level (10 to 80 dB SPL) 80/s interleaved random stimulus design. b ABR waveforms from a single rhesus macaque run on a 7-frequency (0.5 to 32 kHz), 14-level (20 to 85 dB SPL) 60/s interleaved ramp stimulus design. Overlaid are waveforms acquired using a single-frequency 30/s conventional approach. Data from 16 kHz are shown for both ferret and rhesus macaque. c–e Average ABR thresholds, wave 1 amplitudes and wave 1 latencies from rhesus macaque (n =4 ears), comparing 60/s interleaved ramp with 30/s conventional. Wave 1 amplitudes and latencies are assessed at 20 dB re. ABR threshold (i.e., sensation level, dB SL). Error bars in all panels indicate ±SEM.
