Research summary
The purpose of this study is to assess speech perception amongst existing cochlear implant users when using a new implantable middle ear microphone (TubeMic). The TubeMic is a micro-electrical mechanical system (MEMS) microphone. The microphone housing is secured to the skull with a fixation device, and has a wire coupled to the ossicles of the middle ear which when vibrating in turn move the diaphragm. The current study will present BKB sentences to a TubeMic coupled to the ossicular chain of cadaveric specimens and record the output to present directly to the speech processor of cochlear implant users. A further pre-recorded set of BKB sentences presented to a standard external cochlear implant microphone will be used for comparison. The study is central to informing a further project which will eventually implant six existing cochlear implant users with the TubeMic with separate ethical approval.
