Summary

This study aims to investigate the effect of stimulation parameters and different electrode modes on speech perception in adult cochlear implant recipients.

Detailed description

Performance of four programs (MAPs), each with a different rate, PW and stimulation mode were evaluated, all using 8 maxima: (i) 900 Hz rate, 25 µs PW Default (ii) 900 Hz rate, 50 µs PW LP1, (iii) 500 Hz rate, 100 µs PW LP2 all using Monopolar stimulation mode, and (iv) 500 Hz rate, 100 µs PW using an investigational stimulation mode LP3

Conditions

• Hearing Loss, Sensorineural

Interventions

Type	Name	Description
DEVICE	Program using default MAP	Each MAP uses a specific combination of stimulation parameters and electrode mode.
DEVICE	Program using low-power 1 (LP1) MAP	Each MAP uses a specific combination of stimulation parameters and electrode mode.
DEVICE	Program using low-power 2 (LP2) MAP	Each MAP uses a specific combination of stimulation parameters and electrode mode.
DEVICE	Program using low-power 3 (LP3) MAP	Each MAP uses a specific combination of stimulation parameters and electrode mode.
