- Cochlear Implant (CI) is a medical device that partially restores hearing sensation to profoundly deaf people by electrically stimulating the surviving auditory neurons.
- CI users have trouble with speech recognition in noisy environments and various
aspects of music perception
- F0 is not faithfully encoded by CIs which presents problems in music perception
- Some CI users have residual low frequency acoustic hearing up to ~1000 Hz
- When a hearing aid used to provide low frequency acoustic cues for CI users, their speech recognition in noise and music perception greatly improve
- With no residual hearing, a tactile aid could help
- Evelyn Glennie:
Hearing is basically a specialized form of touch. Sound is simply vibrating air which the ear picks up and converts to electrical signals, which are then interpreted by the brain. The sense of hearing is not the only sense that can do this, touch can do this too.
- Vibration and vibrotactile feedback to accompany music and sonic cues can enhance the experience for performers and listeners alike
- performer-instrument relationship for augmented/digital instruments

- Vibrotactile thresholds tested at different sites
- Vibrotactile perception adaptation
- Frequency interval detection
- Melodic contour detection, improved with training
- worse than normal hearing, comparable to CI hearing
- approx. 7% improvement on melodic contour with haptic feedback and CI simulation
