Preliminary studies on our first patient with a multiple channel cochlear implant (Tong et al., 1979) showed that he was able to associate the hearing sensations produced by electrical stimulation of residual auditory nerve fibres with different vowel (spectral) colours. The frequencies characterizing the vowel colours produced by stimulation at single scala tympani electrodes were, in general, closely related to the tonotopical organization of the� cochlea. Furthermore, results from these studies indicated that the pitch produced by single-electrode stimulation increased with pulse rate, and that the loudness increased with current level.
