Pulse-shape efficiency ordering holds across animal and human studies

Evidence

Finally, the difference in efficiency between the various pulse shapes was consistent with results obtained in previous animal and human experiments (Miller et al. 2001 ; Carlyon et al. 2013 ), showing that, to elicit responses of equal amplitude, pseudomonophasic pulses with a gap between the two phases require a lower current level than symmetric pulses while triphasic pulses require a higher current level. — Dijk, Pim van, Physiology, Psychoacoustics and…, 2325
