Effects of Pulse Width, Pulse Rate and Paired Electrode Stimulation on Psychophysical Measures of Dynamic Range and Speech Recognition in Cochlear Implants

Abstract

CIS strategies tend to perform better than PPS strategies. PW, rate and paired stimulation have little effect on speech perception scores. However, they do have predictable and independent effects on both T and M levels for all strategies tested. The relationships found allow the improvement of the versatility of current fitting software and provide a basis to let the fitting software automatically adjust T and M levels if the PW or rate are adjusted in an existing program.
