The role of first formant information in simulated electro-acoustic hearing

Significance of output:

An increasing proportion of cochlear implant recipients retain some natural residual hearing in the low frequency hearing range after implantation. Combining such residual hearing with electrical stimulation from the cochlear implant can be highly beneficial. We have found that a specific speech cue, the first formant, provides much of this benefit. The key implication is that usable hearing range is more important than frequency resolution in determining benefit. This JASA paper therefore provides better guidance to the hearing and ENT community about who will benefit from residual hearing with a cochlear implant, with implications for surgical management and candidate selection.
