TABLE II.

Current level mappings. All listeners used a 22-electrode array, where lower values indicate closer proximity to the base of the cochlea. AM depth is expressed relative to the dynamic range, or the CUs between T and M levels. Because some listeners required level adjustments to maintain equal loudness, the final mapping levels were reported. Listener IBF's MAPs were lost when data were moved from the testing computer to the server where data are stored onsite.
