Up to 22 high-resolution bandpass fi lters provide spectral energy
estimates over the frequency range 100 to 8000 Hz, depending
on the program settings. Filters with the maximum outputs can be
selected. These can be varied. The program determines the fi lters
selected and hence the electrodes stimulated.
Eight fi xed high-resolution fi lters for selecting and customizing
acoustical amplifi cation over the range 125 Hz (approx) to 1.8 kHz
(approx).
