Cochlear Implants

In 2015, the first experiment involving cochlear implant users took place within the new laboratories of the Hearing Systems group at DTU. This experiment aims at better understanding the different perceptual dimensions of pitch in cochlear implant (CI) listeners. The cochlear implant, or so-called ‘bionic ear’, is a prosthetic device that restores sound sensation to severely hearing impaired listeners. Unlike hearing aids that deliver amplified sounds to the ear, the cochlear implant is placed within the inner-ear, the cochlea, and directly stimulates the auditory nerves. Although, the device was very successful in restoring speech perception a quiet environment, more research is needed to improve the overall sound quality, the perception of speech in noise and the enjoyment of music.

The Hearing Systems Group (DTU Health Tech) and Oticon Medical are looking for a candidate for a fully funded three-year PhD on the topic of “tactile stimulation to improve music perception in cochlear implant users” to start in the mid to late 2019. Read more about the PhD position here

In 2014, Jeremy Marozeau joined the faculty in Hearing Systems. His research focuses on the perception of music and voice pitch information for people with a cochlear implant.

Cochlear Implant testpersons
At the moment we are especially looking for users of both a cochlear implant (CI) and a hearing aid in combination (bimodal users) as participants for hearing studies. All the testing will be done by experienced researchers using approved clinical and research equipment. No alteration will be done on your own sound processors. The experiments will not interfere in any way with your regular treatments.
