Reproducing the Pure Tone: CURRENTLY SUSPENDED
Background
An individual with a cochlear implant receives an electrical signal rather than an acoustic signal to initiate stimulation of the auditory cortex of the brain. Although implantees are able to interpret this information to understand the sounds in their environment, with current cochlear implants the stimulation of an electrode within the cochlear does not elicit the percept of a 'pure tone' but rather a buzzing or noise-like percept. It is thought that by stimulating the cochlear in a way that is more akin to that which occurs in nature, a pure tone percept could be produced.
Detail
This project is closely related to other HEARing CRC research on the application of neural models in sound coding for cochlear implants.
Neural models in sound coding are complicated and in their development it may be appropriate to address a sound processing scheme using a single pure tone as an initial step, to see if the sensation can be made to more accurately reproduce the natural percept of a pure tone. If this can be achieved, the processing system can be applied more broadly to address the far more complex interpretation of speech signals and other sounds.
