TABLE 2.

Results of pitch matches

Conditions are abbreviated by the electrode number followed by the pulse rate of the electric pulse train. Conditions that were run together are enclosed in a solid box in the second column. “Time”, in this and Tables 3 and 4 refer to the experience of the listener prior to the measures being obtained: Pre at the start of the tinnitus study, prior to any microphone or mp3 input. Post after all stages of the tinnitus study, and after some additional period of listening in “speech” mode (i.e., through the microphone input). Other abbreviations refer to the phases of the tinnitus study, in the order completed before the measures, where m after listening through mp3 player via auxiliary input, w washout period (speech processor removed), and s speech mode (microphone activated). The column labelled “start” shows the geometric mean of the range of starting frequencies used for each match, followed by the range in octaves. The next three columns show the mean match in Hz and the SD’s in oct of the start frequencies and of the final matches. The last column shows the correlation between the start and final frequency Conditions where the SD of the matches was significantly less than that of the start values, and where the correlation between match and start value was insignificant, are shown in bold
