Table was originally published in Billings et al, 2012.4 Note that the parameters listed are specific to the conditions used to generate the waveform data presented in Fig. 3 and do not necessarily represent all conditions presented in each study. The eight studies included represent aided CAEP data in the literature for which unaided and aided waveforms were able to be reproduced.
*Reference does not state whether this value refers to onset to onset or offset to onset. All other ISIs refer to offset to onset. HL, hearing level; ISI, interstimulus interval; MCL, most comfortable loudness; ppeSPL, peak-to-peak equivalent sound pressure level; SNHL, sensorineural hearing loss; SPL, sound pressure level.
